Interroom doors: the guide of the buyer

The Choice of this or that door for your house, office or a summer residence can become the original compromise sometimes. Really, not always is available full and a trustworthy information about the elements making the formula of quality in this connection the choice occurs on the basis of very approximate and partial estimations which frequently appear erroneous.

INTRODUCTION

It also has served as the reason of creation of the practical guide for choice interroom doors. From experience of daily work the simple, clear guidebook, capable to give to consumers a concrete reference point in search of interroom doors also has been prepared.

WOOD. INFINITE HISTORY

Close, firm, warm, valuable, live, hospitable: these adjectives to a tree bear on themselves the press of our history, and in this friendly and family element thousand threads of an everyday life which weave a way of our civilisation are learnt.

Trees of our woods are natural riches which are updated by self-reproduction and consequently it is necessary in appropriate way and to approach to it. To take from wood that wood can give without infringement of natural balance, - and means use of these riches with mind and care of that it remains viable and did not lose the value.

Constant development of technical thought allows to organise more rational and manufactures without waste. The most developed manufactures in area derevoobrabotki invest a large quantity of human energy, money resources and knowledge for protection of a wood cover worldwide also by constant improvement of all production. Results of search open horizons to the high technology manufactures (as, for example, manufacturing wood-fiber and drevesnostruzhechnyh plates, bar type-setting wood and plywood from a poplar), being the important gain in the field and allowing to exclude losses, to use materials of the small sizes and strongly to increase parametres of stability and durability of products that became possible after variety of researches in specialised laboratories. From this point of view advanced derevoobrabatyvajushchie manufactures are in avant-guard of struggle for environment preservation.

THE TREE. THE ANTIQUE AND MODERN MATERIAL

Since an ancient time the tree represents a traditional material for manufacturing of door and window covers. Thanks to isolating from a cold and noise to properties, thanks to flexibility in application and simplicity in service, to the big variety of colour shades and structures of various breeds of wood, the tree became and remains the most applied material by manufacture of interroom doors. Thanks to technologies and processings (drying, impregnation, toning, varnishing etc.), applied industrial derevoobrabatyvajushchimi the enterprises, interroom doors from a tree give to users additional quality assurances, durability and stability of a product.

Under the certificate of German Institute of the "Know-how" of the covers, being the establishment studying behaviour of various materials, wooden cover considers very good by following criteria of an estimation: a variety of colours, possibility of processing both in the sizes, and under the form (a variety tipology), firmness to deterioration and atmospheric factors, water resistance (permeability of joints and firmness to a moisture direct hit), thermo- and sound insulation, firmness to a condensate, cleaning, repair.

The tree has one more property which distinguishes it from other materials: it live also reflects in itself incomparable symbols not only breeds of wood, but also an individual plant from which it occurs. The tree, it is individual, unique and is simultaneously similar to other trees from this woods on structure development, on lines of fibres, on presence of the small healthy knots doing a tree at once recognised as the present expression of a life in a plant. Thereupon, the certain door or window cover made of the same wood, can differ one from another, on colour, for example, leaving, nevertheless, invariable typical characteristics. If by manufacture of doors and windows from a tree results of researches and technological development are used, it allows to reach and support characteristics and guarantees on a product from a tree same or even above, than from any other material.

THE DOOR. FUNCTIONS, ELEMENTS AND TECHNOLOGIES: ATTRIBUTES OF QUALITY

WHAT MEANS THE DOOR?

The Door open and close, pritvorjajut and cover, plough up and, at last, a door clap. For a door expose and at a door meet. You can roughly ask to close a door from an opposite side or will tell that will wait for you all night long at it. The closed door can seem mystical, uniting, forbidden, close, haughty, discouraging, patronising. If claps a door someone is angry; sometimes, the truth, it can cause draughts. Under a door overhear; behind a door tears or smiles hide; at a door are late, saying goodbye. The door is border between your internal I and an external world.

TASTE QUESTIONS

There are many reasons which define purchase of a new door for inhabited and uninhabited premises: a lot of empty seat is required to someone, and he wishes to create more rational division of space of the house; someone is more sensitive to a problem of style and searches for especially refined design, giving particular attention to furnish and details; there is someone, who wishes to be released in the silent corner to leave behind a door daily cares, problems and own failures; someone simply wishes to replace old, lost prigljadnyj a kind and creaking doors; also there is someone, at last, who wishes to introduce a fresh stream of novelty and to give to house furnish personal shades.

The Choice of doors is huge, and it is caused by set of tastes of buyers. But, without dependence from a style of life, the basic requirement to a door was and there is a guaranteed quality and a constancy of characteristics in time.

ELEMENTS OF THE INTERROOM DOOR

the Falsh-box: the Finished article from a file of a pine or sheet zinced iron. It is built in an aperture and serves for improvement and simplification of process of installation of door or window cover. Unfortunately, in Russia of a falsh-box have not found due application owing to that our fitters of doors and builders prefer zapenivat a box in an aperture and-or to establish a box through special metal corners. It simplifies, accelerates and reduces the price of process of installation, but do not forget that foam in some years can start to be strewed and the door will lose rigidity of fastening in stenovom an aperture.

the Box: It is a design from motionless profiles of a door on which the cloth is hung. The door box consists from 2-uh vertical racks and a crossbeam. A box happen to longitudinal cuts for telescopic platbands and without them. Usually a box make either from MDF, or from shponirovannoj lamelnoj wood, or of a tree file. The most proof to changes of temperature and relative humidity are first two variants.

the Cloth door: the Mobile part of door cover which covers and opens an aperture in a wall. Cloths happen smooth deaf persons, to convex and flat panels which are made from shponirovannogo MDF or DSP, and also of a wood file more often. Massive panels at sharp changes of relative humidity and in dry premises can change the geometry and decrease on the area that leads to occurrence lengthways shtapikov not painted over sites of panels. Cloths also happen to cuts under glass, with lattices of various design. The most often met structure of cloths consists their internal skeleton of a file of coniferous breeds of wood with the cellular filling, giving to a cloth the raised firmness and a constancy in time of its geometrical sizes. Cloths with cellular structure easier (about 10-15 kg) that reduces additional loading by loops. Cloths from a file and with filling from DSP heavier (about 20-30 kg) also demand application by factory of more massive loops. Nevertheless, we recommend not to leave a door with cloths from a file abroach for the long period of time.

Platbands: the Elements covering junctions between a door cloth and a box, on the one hand, and if that is applied, falsh-boxes with another. Platbands are made from shponirovannyh MDF or plywood, and also of a wood file. Platbands happen flat, figured in a Baroque taste and semicircular more often. Platbands also share on unprofitable and telescopic with wings for an insert in corresponding a box. Application of telescopic platbands improves aesthetic perception of a joint between a box and a platband and allows to regulate width of a box from 1 to 2 see

Accessories (accessories): the Handle, the lock, a sealant, loops, glasses.

THE CORES OF TYPOLOGY AND THE OPENING DIRECTION

the Cores tipologijami are: (1) - smooth or "deaf", (2) - opaque rectangular frames (smooth "deaf" or convex filyonchatye), (3) - with long glass, (4) - transparent rectangular frames, (5) - lattices opaque "deaf persons" and with transparent glass.

the Basic types of opening: (6) - odnopolnye raspashnye, (7) - dvupolnye raspashnye, (8) - sdvizhnye on a wall, (9) - sdvizhnye in stenovoj an aperture, (10) - developing "book", (11) - salonnogo type (the cloth can open in both parties stenovogo an aperture).

opening Directions: In Russia are defined as follows: if to assume as a basis that the door should be opened, having pulled on itself a cloth, if the cloth appears after opening on the right also opening is considered a direction right; if the cloth appears after opening at the left also opening is considered a direction left. Notice! In Europe the opening direction is accepted the return from Russian because there this procedure of definition of opening of a direction of a door make, pushing a door cloth from itself. Accordingly, if the cloth at its pushing leaves to the left on European such opening it is considered left if the cloth at its pushing leaves to the right opening right.

the Sizes: Doors gather factories manufacturers on the certain standardised sizes. The European standard sizes "on a cloth" (actually it is the effective size of an internal light aperture of a box) are that: 600 - 700 - 800 - 900 mm on width and 2100 mm on height. In Russia standard the height is considered of 2000 mm which have got to us from a Soviet period. It is necessary to notice that recently a lot of the new habitation, from national to elite, is under construction with the apertures having the size of an internal light aperture of a box "under Europe", i.e. height 2100 mm. For calculation demanded stenovogo an aperture take the conditional size on a cloth and add 10 sm on width and 5 sm on height. Thus between an external surface of a box and stenovym an aperture remains on 1 sm for zapenivanija or other elements of fastening.

TECHNOLOGIES OF PROCESSING OF WOOD AND ITS DERIVATIVES

Wood is an organic material and can be subject to chemical, physical, biological influence. In this connection wood, in the course of industrial production of doors, is exposed to phasic processings of a various kind which give to a final product the properties which are meeting the requirements of the market about a constancy of characteristics. Only thus it is possible to guarantee mechanical firmness, an invariance of the linear sizes, stability of a product while in service in which current often there are changes of humidity and temperature in premises.

Before the beginning of any process of processing of wood it is necessary to spend serious and effective processing in sushilnyh chambers that promotes stabilisation of internal humidity of wood.

wood Drying: Ability of a tree to absorb and keep a moisture does necessary, till the beginning moment derevoobrabotki, process very accurate prosushivanija. This big image will exclude possible problems with a swelling of wood and change of its geometry depending on level of relative humidity indoors.

Artificial drying is spent by different ways: in strongly discharged environment, by means of moisture condensation, by air obduvki. All cycle of drying demands presence of very difficult equipment in order to avoid curvatures of wood, cracks or creation of internal pressure which can arise because of small defects of drying. Good stability of wood is reached already at 10-12% of relative internal humidity.

The Constant attention advanced derevoobrabatyvajushchih manufactures to problems of reduction of their waste and marriage by wood use by more rational way, on the one hand, and by use of qualitative wood with high degree of stability, with another, has made possible manufacture various derivative of wood which have very good qualitative and technical characteristics.

Plates from a fibre of average density MDF: fibrous plates of a homogeneous thickness are developed from intended on deforestation and a waste (scraps) derevoobrabotki which mill to small cubes (chips), subject processings by steam under a high pressure and, in a consequence, submit on rotating disks defibryora (tyorochnoj cars). All wiped and svojlachivaemyj the material arrives at once on drying and the subsequent sklejku. This type of a half-finished product has excellent characteristics of compactness, coupling of fibres, and also a constancy of the geometrical sizes in a current of the long period of time. The strength of this material is exclusively favorable parity between hardness and thickness: sheets from MDF can be from 4 to 22 mm. Recently door blocks with boxes and platbands from MDF, covered with an interline interval of valuable breeds of wood or new enough material - a synthetic interline interval "laminatinom", many times exceeding natural "relative" on many indicators and first of all on wear resistance began to appear.

Listelnaja (reechno-type-setting wood): It is a wood half-finished product, it is made by pasting listelej (reek) of the dried up pine or a poplar, considering raznonapravlennost fibres of wood next bruskov for the best stability of all block. For example, for the door boxes more often made of such material, pasting occurs in two layers with intermediate dempfirovannym sheet of thin plywood. Subsequently such "pie" for masking of joints cover with a natural interline interval of valuable breeds of a tree. The finished goods possess aesthetic characteristics of a file of a tree, but with more optimised operational characteristics.

Drevesnostruzhechnaja plate DSP: It is the panels of a homogeneous thickness consisting of fragments of wood (shaving), mixed with the binding material having in the basis synthetic pitches, and received by pressing.

Plywood from a poplar: a Material consisting of set of sheets of wood of a various thickness, pasted one on another with a crossing of a direction of a course of fibres of the next layers for the best stabilisation of characteristics of all product. Possesses high stability and hardness.

Processing by drying:

Definition: the Processing which purpose is decrease in relative internal humidity of wood for the purpose of increase of its hardness, stability and durations of term of its service.
Advantages: the interroom doors made of similar wood are not deformed and keep aesthetic and functional properties, invariable in time.

Manufacture of panels from MDF:

Definition: Manufacture of a half-finished product from wooden chips (small cubes of the wrong form), fibres providing excellent coupling and compactness.
Advantages: Application of this material in manufacturing of interroom doors allows the last to get properties excellent planarnosti surfaces of a cloth, superficial hardness and resistibility to blows. Besides, excellent aesthetic results with excellent possibilities on painting are reached. The given material is applied in the broadest image to manufacturing shponirovannyh and the laminated platbands, doborov, racks of boxes, pantografirovannyh cloths under painting and various overlays for entrance doors.

Manufacture lamelnoj wood:

Definition: It is made by pasting bruskov from the dried up wood of coniferous breeds.
Advantages: It is used for manufacturing of interroom doors which show appeal of doors from a tree file. It is characterised by special firmness to deformations, cracks and drying with reduction of the sizes. It is irreplaceable by manufacture shponirovannyh racks of boxes and shponirovannyh obvjazov racks of cloths. On the properties and prestigiousness does not concede to massive wood.

Manufacture DSP (a wood-shaving plate):

Definition: Manufacture of the half-finished product consisting from struzhechnyh of fragments of wood, got mixed up on a binding component from synthetic pitches and subjected to pressing and sintering.
Advantages: Application of the given material in manufacture of interroom doors allows to reach considerable results on planarnosti and stability of the geometrical sizes of a door. Carries also shumopogloshchajushchie functions.

plywood Manufacture:

Definition: consists of set of sheets of wood of the various thickness, stuck together among themselves special glues, on bolshej degrees, on the basis of synthetic pitches. For increase of stability wood sheets stick together with raznonapravlennymi with fibres.
Advantages: Application of the given material by manufacture of interroom doors allows to reach good results of durability and stability in time. More often plywood sheets are used by manufacture shponirovannyh by valuable breeds of wood of platbands, boxes and their dilators (doborov). Plywood sheets are applied also to manufacturing pantografirovannyh cloths and decorative overlays for entrance doors.

IN MORE DETAILS ABOUT DOOR COMPONENTS

THE BOX:

The Necessary component of a door on which cloths and to which dilators and platbands are attached are hung. It is made of various materials depending on the subsequent application: listelnaja wood, plywood from raznonapravlennyh sheets of a poplar and the panel from MDF. By manufacture of racks of boxes further on them paste sheets of an interline interval from various breeds of wood: a nut tanganika (Aniegre), mahogany, an oak, the European nut, a sweet cherry, a nut mansonija, a tic, an ash-tree, a pear, a birch etc., or box racks are painted with special dyes on poliuretanovoj or more modern water basis. A box happen the diversified forms: from traditional rectangular to rounded with various diameter of curvature and the difficult figured. Racks and crossbeams of a box are joined to rectangular section under 90 degrees, and round a box are joined under 45 degrees with obligatory zarezkoj racks industrially on the high-precision equipment. In boxes in special longitudinal grooves are necessarily established rubber uplotniteli white, black or brown colours. To boxes are completed or unprofitable flat platbands, or the telescopic flat, rounded or figured platbands. Racks of boxes are applied also to a frame of the apertures rectangular and rounded in the top part (an arch frame). In this case in box racks there is no quarter sample for a cloth. The CLOTH:

The Door cloth is made in three ways:

1. A hollow cloth (tamburatnoe with cellular structure). Similar cloths are made by the large industrial enterprises applying the advanced technologies. The cloth consists of an internal skeleton from coniferous breeds of wood with lateral thickenings in an average part of a cloth for the subsequent insert of locks; periodic structure from the pressed cardboard of type "beer honeycombs", which application are raised essentially by stability of the geometrical sizes of a cloth, and also facilitates cloth weight; superficial sheets from MDF. "Pie" made in a similar way becomes covered by an interline interval of various breeds of wood: the nut tanganika (Aniegre), mahogany, an oak, the European nut, a sweet cherry, a nut mansonija, a tic, an ash-tree, a pear, a birch etc., or becomes covered by special dyes. Similar cloths are made as and a quarter on each side cloths and in its top part, and without a quarter. In the latter case cloths are hung on a box with special invisible loops, and such door blocks become reversive, i.e. with an independent direction of opening that dares at the moment of installation and allows to optimise warehouse stocks both at factories manufacturers, and at their distributors in the various countries. Hollow cloths are rather easy that allows to apply more tiny loops of type Anuba. On the basis of similar cloths more difficult are made as simple smooth, and filyonchatye variants of cloths.

2. A cloth from listelnoj (type-setting) wood. Consists of structure completely made of listelnoj (type-setting) wood covered with an interline interval from various valuable breeds of wood. Usually to structure from lamelnoj wood are completed smooth or convex panels, and also decorative glasses of various design. The given product possesses all high technical characteristics and aesthetic prestigiousness of natural massive wood. Thus cloths from type-setting wood possess very high firmness to changes of temperature and relative humidity at heating inclusion in a cold season. The effect of redrying, in case of natural massive wood can cause various unpleasant changes of geometry of every possible components of a door. If prestigiousness of a natural tree for you is more important than a practicality of type-setting wood, and high cost of doors from a tree file are not for you a problem, that in the hot image we advise you to take care of the constant control over temperature and relative humidity indoors, making artificial humidifying of air by means of damp cleaning and rubbings, and also by means of plants.

3. Cloths with filling. Similar cloths are made of hollow cloths, but instead of cellular internal structure filling from DSP or other materials, giving to a cloth additional stability and the raised level shumopodavlenija, and also firmness to an open flame is applied. Cloths thus turn out heavy enough (25-40 kg), and for their simplification in a filling material make longitudinal through parallel apertures.

SOME STAGES OF THE PRODUCTION CYCLE:

To achieve from a product of high level of functionality and an appearance aesthetics it is necessary to pass numerous stages of modern industrial production before. Accuracy, reliability and a technological level derevoobrabatyvajushchego the equipment have fundamental importance for reception of a qualitative finished article and for maintenance of the quality standards while the necessary flexibility of manufacture caused by application of electronic control systems of the equipment, does possible for the industrial enterprises to offer on the market wide and various scale of models.

Each of described below industrial production stages allows to guarantee quality of an end result and a constancy in time of characteristics of a finished article. We will more low result the short description of some phases of polishing, toning and the varnishing which is most important from the point of view of the consumer.

Polishing: it is necessary for giving of a surface of a cloth and a box of high smoothness for achievement of high aesthetic results. Usually polishing process is multiphasic process combined with process of a first coat of cloths before the subsequent toning and finishing varnishing of components of a door.

Toning and varnishing: the Given stage, in a combination to polishing, is the most delicate production bad or good results after which are most appreciable in a final product even for uninitiated eyes. The given process includes drawing on all surfaces of components of a door of two or more varnish coats for closing of all time of wood, protecting it thus from humidity and reaching excellent aesthetic results. Before the recent past to these purposes were applied poliuretanovye varnishes, but in connection with the increased requirements of the European ecologists, at the moment the given varnishes are actively superseded by more modern varnishes on the water basis, not conceding than under the basic characteristics.

Various characteristics of four basic types of varnishing:

a) Transparent type: it is reached by drawing of a thin layer on all external and internal surfaces of a product of especially firm and proof varnish.
b) Tonirovannyj type: it is reached by drawing on all surfaces of a product of colour dye. After the given preprocessing drawing of a transparent layer as in point (a) is made.
c) Krashennyj type: it is reached by consecutive drawing of several layers of a matte or brilliant varnish on all surfaces of a product.
d) Krashennyj on poliuretanovoj to a basis with brilliant furnish type: it is reached by drawing on all surfaces of a product of two or more layers of a varnish covering on poliesternoj to a basis. This type of a product mixed with special components, makes reaction, forming very firm and strong film with high reflecting properties and shine. Subsequently make the finishing polishing guaranteeing high aesthetic result and the big prestige.

ACCESSORIES:

Today the choice of an interroom door is beyond only a tehniko-practical estimation, and became means for expression of personal style and taste. At a choice of a door for furnish of your premise the beauty and functionality are equally important. The secret of the balanced choice consists in an attentive estimation of details: in a qualitative door, actually, and accessories should answer accurate consumer criteria. Handles, locks, uplotniteli and loops are exposed strozhajshimu to the control confirming their quality.

Locks: their function is blocking of opening of a door in stenovom an aperture. Last years constant search of new decisions has allowed to offer consumers huge scale of the locks, capable to satisfy the most exacting buyers who are paying attention not only on functionality of the lock, but also on style. With interroom doors the European manufacturers usually offer locks under suvaldnyj a key (Patent), under the cylinder (Yale) and under a toilet latch (WC). These locks are made in many furnish, but is used blestjashchjaja a brass, brilliant or matte chrome more often. Locks under a toilet latch establish in baths and toilets, but began fashionable to apply them also in bedrooms and other premises. The toilet latch from outside, the opposite handle, has a cut. If someone feels badly indoors at you possibility by means of a simple coin will open a door.

Loops: loop function consists in fastening of a door cloth on a box. Loops happen visible and invisible. In the latter case, when two loops establish from above and from below cloths, it allows to do a door of independent opening, i.e. reversive. The similar innovation carries as well more advanced aesthetic aspect, but obliges manufacturers to do the cloths deprived of a quarter. Loops are usually combined with colour of the lock.

Handles: Anything so does not decorate a door as the handle which has been harmoniously picked up to design of a door. Style, quality and a variety of models are those necessary requisites which this irreplaceable accessory should possess. Sometimes the handles offered by sellers so many that becomes difficult to be guided in their choice. I will afford some councils. First of all colour of the handle should be combined with colour of accessories of furniture sets of your dwelling, and the design of the handle should be combined with design of a door. Before a definitive choice is advised to touch all handles literally. Tactile touch will help to dare at this or that model. The handle can leave pleasant and unpleasant sensations on your palms. Pay also attention to the manufacturer. In the basis the handle has a massive or hollow piece of a brass on which in the course of manufacture are put from 1 to 10 protective layers guaranteeing, naturally, in different degree an invariance in time of appearance of the handle. Pay attention to quality if do not want that after a while your handles have not darkened or not oblezli. Do not process the handle aggressive solvents of type acetone and do not use for cleaning of handles by abrasive sponges. All handles last layer have a varnish covering of different degree of hardness and stability to solvents and mechanical influences. Therefore do not save on handles. Let they please you many long years!

Uplotniteli: Correct installation of a sealant in a box guarantees increase of sound insulation of the door block. Uplotniteli usually establish industrially on perimetre of all box. The good sealant promotes also to a relative thermal protection of a premise, and besides strongly reduces penetration of a dust into rooms. The sealant also serves for prevention of a bump of a cloth about a box, doing closing of a door more bezshumnym. Uplotniteli happen the most different in materials of manufacturing and colours.

Glass: In interroom doors glass carries more likely decorative functions, and also promotes the best light exposure of corridors and rooms on North sides of houses. Glasses happen transparent and matte, white and colour, simple and tempered, smooth and with perimetralnym fatsetom, to colour inserts and peskostrujnym drawing. Beautiful glass is very seriously reflected in design of a door, raising its prestigiousness, but, unfortunately, the glasses especially tempered and with fatsetom, are expensive enough. Glasses, also, can break. If All of you have stopped the choice on a door with glass, we advise, in a case if you have children or elderly relatives, to choose the tempered glasses which in case of a beating are scattered on the small granules which do not have cutting surfaces (type of bus glasses), or tripleksnye the glasses having a transparent film between two layers of glasses. Do not save on glasses. Not tempered glass can, in case of its beating, to make a number standing invalids.

SPECIAL TYPOLOGY OF DOORS

In practice of civil building quite often there is a necessity in the doorway with special characteristics, basic of which are pozharoprochnost and shumopodavlenie. The doors, different these features, are allocated in a special class of doors and have concrete application.

FIRE-RESISTANT DOORS

There are much enough strict specifications which are considered at manufacturing of the given doors which problem is protection of a premise against direct fire and otsekanie a smoke in the stipulated time interval. On the given time intervals of a door are subdivided into classes of resistance till 30, 60, 90 and 120 minutes. Interroom doors are made with firmness to an open flame not above 30 minutes. Longer interval of time is maintained only by metal doors with special filling of cloths and boxes. Usually in houses such doors are established extremely seldom, and their application basically is limited to installation in uninhabited premises, such as offices, hospitals, shops etc.

SHUMOPODAVLJAJUSHCHIE DOORS

Necessity for similar doors arises daily including in our dwellings. At whom the child is engaged houses in music, someone has a house cinema and at viewing of films would not like to disturb house, the head is ill someone, and he wishes to retire from the noisy company. Here those some cases when additional shumopoglashchenie at an interroom door it is necessary. It is necessary to note, what even in usual interroom doors without special operational development probably to have essential enough level shumopodavlenija in 10/12 dB. It is necessary to have in view of that deaf filyonchatye doors have bolshee shumopodavlenie rather than doors with glass or doors with hollow cloths. It is possible to raise independently to 12/15 dB shumopodavlenija a usual interroom door if it is good zapenivat space between a box and stenovym an aperture, and also to build in downwards cloths special rubber automatic thresholds which cloths at opening are cleaned in a cloth body, and at closing fall downwards, increasing shumopodavlenie and excepting draughts that too it is important. Doors with higher to 22/25 dB shumopogloshcheniem usually have thicker cloths with special internal filling from punched DSP or synthetic cotton wool at obligatory use of an automatic rubber threshold.

THE SPECIAL CLASS OF INTERROOM DOORS FOR PUBLIC PREMISES

The Given doors are intended for simplification of movement on public premises of invalids on carriages. Usually such doors have width of a cloth not less than 80 see, special returnable loops, lever handles at lower height: about 90 sm (usually 100-110 see), and also, in case of doors with ostekleniem, glasses, whose bottom edge should not be above 40-45 see from a floor.

CARE OF DOORS

The Door is the same important component of furnish of interiors, as well as furniture, and requires simple and periodic service that its appearance remained many long years, pleasing your eyes.

At door cleaning it is very important to adhere to some base principles. First of all use only special substances. The most part of cleaners with the dispersion, available on sale does not render any protective effect on a door, and in certain cases can even damage to an external varnish covering. Use of the solution consisting on 90% from tap water and on 10% from spirit can be the simple decision of this problem. Even casual use of washing liquids or abrasive powders which can enter chemical interaction with wood of doors categorically is forbidden, accelerating thus its ageing.

CLEANING

Using above described water solution of spirit it is possible thoroughly, quickly and effectively to clear a door surface. Clearing procedure is simple: moistened in a solution and well wrung out rag wipe all surfaces of all components of a door, having removed a dust. Repeatedly to make the same procedure by almost dry rag, having removed moisture traces.

Attention!! At the work, the walls connected with plaster, or at work on the device of floors (the tile, a parquet and other) arises a situation of potential danger to doors as at the given works chemical components which can seriously worsen quality of superficial furnish of a door are applied. If there is no possibility to remove cloth with boxes, temporarily to store them indoors deprived of a dust it is recommended to close a box and a cloth polyethylene or in time to delete from doors of a stain of a paint or plaster, and also a dust by means of the rag moistened in soap water.

CARE OF DOORS WITH VARNISH poliesternym THE COVERING

There are doors with shining poliesternym a varnish covering at which it is recommended to examine its condition periodically. Forgetfulness or wrong leaving can promote occurrence of scratches and other superficial defects. Using special processing probably quickly to delete any imperfections of a covering and to return doors prestigious shine of a varnish. I result some simple operations more low:

  • Slightly to humidify and zashkurit the damaged surface in the field of defect with a special small skin. Attention!! Grain of an abrasive surface of a skin or an abrasive disk should be 1000/2000.
  • to Smear on a processed surface a small amount of polishing wax and by means of a special soft rag to rub wax, achieving former shine.

    USUAL LEAVING

    Usual leaving is not connected with necessity of small repair, and limited only to periodic surveys and clearing. Should become good norm to carry out each two years following procedures:

  • to Check up normal functioning of a door and its components (locks, loops)
  • to Remove cloths from boxes to clear loops and again to grease with their suitable automobile semi-fluid greasings. If necessary to adjust loops.
  • to Remove and disassemble locks for cleaning and greasing of its components.

    LONG-TERM SERVICE

    Considering that average service life of a sound interroom door makes 30-40 years, I advise in special cases to make following actions:

  • to Replace glasses
  • to Replace handles
  • to Replace uplotniteli in a box
  • Repeated varnishing of all components of a door.

    After these operations your door will be as new!
