Modern technology insulation windows

A completely new materials and methods have appeared on the change of old and rather time-consuming methods of insulation of windows, thanks to which not only thermal losses are significantly reduced, but also the sealing process itself is accelerated. In addition, the technology of work with modern materials is so simple that it fully allows you to warm up windows with your own hands.

Materials for insulation, their appointment

Newspapers, wool, rags and other materials for insulation windows moved into the past, and their place was taken by various kinds of seals and sealants.

The high-quality seal provides a more dense fit of the sash to a wooden or plastic window frame. At the same time, in plastic windows, the seal also serves to seal the glass package in the frame.

In most cases, the sealant is used as auxiliary material, contributing to the elimination of the slots between the frame, slopes and the windowsill. However, in wooden windows with the help of sealant, a more dense adjacent glass to the frame is ensured.

Thus, combining in the process of insulation of windows, the sealant and the seal can be reduced heat loss up to 90%.

Types of window seals, their characteristics

Modern seals are made by extrusion of synthetic rubber with different polymers. However, from the variety of seals for sealing windows is most often used:

1. Erdm - rubber seal, the main element of which is ethylenepropylene rubber. The color gamut of the EPDM-seal depends on the amount of soot added to the material, in many respects affecting the strength of the product. In this regard, the rubber sealer is produced only in black and gray. At the same time, gray seals are an order of magnitude more expensive than black, although in a slight extent inferior to them for some qualitative indicators.

Pros:

• excellent moisture resistance;
• low residual deformation;
• high rates of atmospheric resistance;
• excellent noise and thermal insulation properties;
• high resistance to ultraviolet;
• small radius of rounding;
• resistance to mechanical damage;
• with continuous stretching, a sufficiently dense angle is formed;
• high strength and elasticity of the material remains throughout the entire operational period;
• durability.

Minuses:

• swelling of the seal under the influence of oils of vegetable and mineral origin;
• unbalanced seal;
• high price.

2. Trev or TEP - thermoelastoplasts formed as a result of a mixture of rubber with polyvinyl chloride. The modified polyvinyl chloride has a homogeneous structure, so at low temperatures, the sealant grubes, and at high - softened, which adversely affects the elasticity of the material. In this case, during operation, the TEP does not allocate any toxic elements, and is also not susceptible to burning, indicating high security insulation.

Advantages:

• wide color gamut;
• the possibility of welding seams in the corners of the profile;
• resistance to chemicals in the form of alkalis, acids;
• small radius of rounding;
• lack of smell;
• low cost.

Disadvantages:

• small mechanical strength;
• when welding the material, rigid angles are formed;
• sufficiently high residual deformation;
• relative resistance to solar rays;
• low elasticity;
• the service life does not exceed 2 years.

TPS is a variety of three, since it is produced by foaming the thermoplastic elastomer. A distinctive feature of the TPS relative to the Tre - the heterogeneous structure, presented by cells isolated from each other, due to which the TPS has higher indicators of heat and sound insulation.

3. SiO is a silicone seal related to the category of special-purpose rubber. In terms of strength and elasticity, SiO significantly exceeds EPDM and TEP seals. In addition, the silicone sealer can be painted, since it does not affect its properties.

Advantages:

• resistance to sharp temperature fluctuations;
• lack of residual deformation;
• chemical resistance to various aggressive environments;
• does not change properties under the influence of ultraviolet;
• excellent waterproof;
• high level of atmospheric resistance;
• long operational period.

Disadvantages:

• minor mechanical resistance;
• high price.

Regardless of the advantages and disadvantages, the seals are still different in the installation method:

• Self-adhesive - represented by silicone, rubber, thermoplastic, as well as foam-foam seals, one side of which has an adhesive basis. Such seals are characterized by simplicity, as well as speed of installation, but also by dirty.

• Sliding - not intended for gluing. To fix the insulation, it is necessary to make a recess into which the tubular silicone seal is laid, rubber or thermoelastoplast. For a stronger fit, the insulation is rolled by a special roller.

• Adhesive - do not have adhesive base, so such seals are fixed on the surface by means of a special glue or silicone sealant. Adhesive type seals include rubber, as well as silicone insulation.

Thus, the EPDM significantly exceeds the TEP seals in many indicators, yielding at the price of SiO, due to which the leading positions occupy among various types of seals.

Types of sealant, their characteristics

Despite the huge assortment series of various kinds of sealant, only 3 types are used for the windows insulation:

1. Silicone sealants, the main component of which siloxane rubbers appear:

• acetate - have high strength and excellent adhesion, mainly with smooth materials. However, the processed surfaces must have increased resistance to acetic acid highlighted in the process of drying the sealant. In addition, working with silicone sealant of acetate type should be carried out in a ventilated room due to the resistant smell of vinegar, which remains preserved until the sealant is hardened;

• neutral sealants are ideal for porous materials, including for the insulation of wooden windows. Unlike acetate, they do not have a sharp smell;

In general, silicone sealants possess the following advantages:

• excellent elasticity;
• resistance to different temperatures;
• lack of shrinkage;
• do not change the original color throughout the service life;
• resistance to many aggressive environments;
• durability;
• acceptable cost.

Minuses:

• not subject to staining.

2. Polyurethane sealants based on polyurethane resins are subject to additional polymerization under the influence of moisture contained in the air. Suitable for both insulation of plastic windows and wood insulation.

Pros:

• excellent heat resistance;
• high moisture resistance;
• the possibility of staining after a complete hardening;
• with significant vibrations are not deformed;
• resistance to most acids, oils;
• high elasticity;
• duration of operation.

Minuses:

• in the process of vulcanization, caustic substances are distinguished;
• high price.

3. Acrylic sealants, based on the manufacture of which are acrylic polymers and water lie, are the optimal choice for embedding fixed and sedentary seams.

Pros:

• high adhesion with many materials;
• resistance to the sun rays;
• the possibility of staining;
• low cost.

Minuses:

• the possibility of shrinkage;
• low elasticity;
• possible deformation of the seams;
• attracts dust;
• over time, yellowing;
• little service life.

Thus, when choosing a sealant, special attention should be paid to their disadvantages that are largely dependent on the conditions of future operation.

Wooden windows insulation technology

The process of insulation of both new and old wooden windows is quite laborious, therefore includes several stages.

Preparation of Ram

The preparation process includes the work of the following order:

1. Remove window sash.
2. Inspect the sash to integrity, and if there is damage - eliminate them.
3. Remove with frames old paint through a spatula or other available tools and tools.
4. Wipe the frames with a damp rag, removing the exfoliated paint and dust.
5. Degrease carefully dry.

Preparation of glasses

To improve adhesion, sealant with frame and glass must be:

1. Press the strokes flat screwdriver and slightly lift them.
2. Remove side strokes, then - bottom, and after it is the top.
3. Remove glasses from the window frame.
4. Clean the glass, as well as landing for glasses place in the frame from the accumulated dirt using a spatula.
5. Wipe with a cloth, degrease and dry.

Warming glass

1. On the perimeter of the frame, in the places of its junction with glass, continuous line to apply the sealant and, until it grabbed, insert the glass.
2. Fix the glass with the assistance of the stroke.
3. Remove excess sealant from the glass after its complete rejection.

Warming of sash

To decide on the thickness of the seal, you will need plasticine and plastic bag. Plasticine rolls in the shape of a tube, a diameter of about 2 cm, stacked into the bag, after which it is placed in places of contact of the sash. The window closes, and after opening on the plasticine, dents corresponding to the depth of the slit are formed. In this case, the thickness of the sealer is taken according to the greatest thickness of the plasticine.

The process of insulation of sash:

1. Application, without tensioning, to the place of its future location and cut into the required segments at an angle of 45 ° C.
2. Gradually, removing the protective paper from the self-adhesive sealer to glue it to the sash.
3. If the seal does not have a sticky base, then the glue is first applied and the sealant is applied to which the sealing bands are then fitted.
4. To secure the sealer at the end of the work, it is necessary to close the window and do not open it within the day.

The insulation of old windows by a similar method is made both from the inner and from the outside.

Warming windows in Swedish technology

Despite the name, the Swedish woodworking technology technology is very similar to the above-described woodworking technology, especially in terms of preparatory work, as well as glass insulation in the frame by sealant. A distinctive feature of the Swedish wind insulation is the groove attachment of the special Eurostrip seal, although it is quite suitable for Erdm instead.

For warming windows in Swedish technology, it is necessary:

• by means of a milling tool around the entire perimeter of the sash to make the grooves in a depth of 0.5 cm, and the width is enough 2-3 mm. At the same time, from the place of fastening the loops, it is necessary to retreat aside by 1-1.5 cm;
• lay the seal in the groove, placing it with a tail down;
• for better fixation, to rotate the seal in the groove using a special roller;
• hit the sash and adjust the fittings.

Despite the simplicity of Swedish wind insulation technology, prices for such a service are only 3-4 times lower than the cost of the new plastic glass. Therefore, if the windows have already been identified and preparing for no more than 1-2 years, then you should look for a cheaper insulation option with a small operating period.

Plastic Warming Technology

Works on the insulation of plastic windows are somewhat different from the works associated with the sealing of wooden windows and include:

• periodic adjustment of fittings, at least once a year;

• replacement of seals when even minor cracks appear on them, signaling about the loss of all elasticity.

Replacing the rubber seal is made like this:

1. Pick up a knife or a special spatula of the editorial edge and, gradually lifting, remove it around the perimeter of the sash.
2. Remove the glass.
3. Remove the old seal, clearing the grooves from the remaining elements of rubber and dirt.
4. Insert a new seal, docked by the ends of the rubber inside the groove.
5. Install the double-glazed window and fix it by the strokes by means of a mounting hammer.
6. Adjust the fittings of the sash.

As an additional measure, the PVC windows insulation must be sealing the place of the frame of the frame, as well as slopes with the windowsill.

Warming of mansard windows

In most cases, the problems with the tightness of the attic of the attic windows arise in the area of \u200b\u200bboth the lower and the upper slopes. Therefore, at the first appearance of a draft, or freezing, it is necessary to insulate the problem areas with basalt or glass gamble.

It does not hurt the installation under the windows of the attic type of heating devices, thanks to which the slopes will warm up, and the condensate is unlikely to appear.

However, to eliminate cracks, it is impossible to use a mounting foam, since it may affect the displacement of the frame on the box relative to the box, as a result of which new cold bridges are formed.

Thus, on various ways of insulation of windows, the price can also differ significantly, folding under the influence of the cost of consumables and work produced. However, all the technologies are so simple that the insulation of windows can be performed with their own hands without resorting to the services of professionals.
