Modern technologies for window insulation

The old and rather time -consuming methods for warming windows by winter have completely new materials and methods, thanks to which not only thermal losses are significantly reduced, but the sealing process itself is accelerated. In addition, the technology of work with modern materials is so simple that it allows you to warm windows with your own hands.

Materials for insulation, their purpose

Newspapers, cotton rags and other materials for warming windows have gone into the past, and their place was taken by various kinds of seals and sealants.

A 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 double -glazed window in the frame.

In most cases, the sealant is used as an auxiliary material, contributing to the elimination of cracks between the frame, slopes and the window sill. However, in wooden windows, using the sealant, a more tight fit of glass to the frame is ensured.

Thus, by combining the sealant and sealing in the process of warming windows, heat loss can be reduced to 90%.

Types of window seals, their characteristic

Modern seals are carried out by extrusion of synthetic rubber with various polymers. However, from the whole variety of seals for sealing windows are most often used:

1. Erdm is a rubber seal, the main element of which is ethylenepropylene rubber. The color scheme of the ERDM seal depends on the amount of soot added to the composition of the material, which largely affects the strength of the product. In this regard, the rubber seal is produced only in black and gray. At the same time, gray seals are much more expensive than black, although they are slightly inferior to them in some quality indicators.

Pros:

• excellent moisture resistance;
• low residual deformation;
• high indicators of atmosphere 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.

Cons:

• swelling of the seal under the influence of oils of plant and mineral origin;
• incomplete seal;
• high cost.

2. TRO or TEP - thermolastoplasts formed as a result of a mixture of rubber with polyvinyl chloride. Modified polyvinyl chloride has a homogeneous structure, therefore, at low temperatures, the seal is coarse, and at high temperatures, it softens, which negatively affects the elasticity of the material. At the same time, during operation, the heater does not emit any toxic elements, and is also not burned, indicating the high safety of the insulation.

Advantages:

• wide color scheme;
• 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.

Flaws:

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

TPS is a type of three, since it is carried out by foaming thermoplastic elastomer. A distinctive feature of TPS relatively three is a heterogeneous structure represented by cells isolated from each other, thanks to which TPS has higher heat and sound insulation.

3. SIO - silicone sealing, belonging to the category of special -purpose rubber. With regard to the strength and elasticity of SIO, significantly exceeds the seals of the ERDM and TEP. In addition, the silicone seal can be painted, since this does not reflect on 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 radiation;
• excellent water resistance;
• high level of atmosphere resistance;
• long operational period.

Flaws:

• slight mechanical resistance;
• high price.

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

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

• Grooves - not intended for gluing. To fix the insulation, it is necessary to make a notch in which a tubular seal of silicone, rubber or thermolastoplast is laid. For a more durable fit, the insulation is rolled with a special roller.

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

Thus, the ERDM significantly exceeds the TEP seal in many indicators, while yielding to SIO in the price, which occupies a leading position among various types of seals.

Types of sealant, their characteristic

Despite the huge assortment series of various kinds of sealants, only 3 types are used to warm windows:

1. Silicone sealants, the main component of which are sulfsane rubber, are:

• acetate - have high strength and excellent adhesion, mainly with smooth materials. However, the treated surfaces should have increased resistance to acetic acid secreted during the drying of the sealant. In addition, work with an acetate-type silicone sealant should be carried out in a ventilated room due to the persistent smell of vinegar, which remains until the sealant is hardened;

• neutral sealants are ideal for porous materials, including for insulation of wooden windows. Unlike acetate, they have no pungent odor;

In general, silicone sealants have the following advantages:

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

Cons:

• are 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 both for insulation of plastic windows, and for wooden insulation.

Pros:

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

Cons:

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

3. Acrylic sealants, the basis of the manufacture of which are acrylic polymers and water, are the best choice for the sealing of fixed and sedentary seams.

Pros:

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

Cons:

• the possibility of shrinkage;
• low elasticity;
• deformation of the seams is possible;
• attracts dust;
• over time, it turns yellow;
• short service life.

Thus, when choosing a sealant, special attention should be paid to their shortcomings, which to a large extent depend on the conditions of future operation.

Wooden window insulation technology

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

Preparation of frames

The preparation process includes the following order:

1. Dismantle window sash.
2. Inspect the sash on integrity, and in the presence of damage - eliminate them.
3. Remove the old paint from the frames by means of a spatula or other available tools and tools.
4. Wipe the frames with a damp cloth, removing exfoliated paint and dust.
5. Degrease, dry well.

Preparation of glasses

To improve adhesion, sealant with a frame and glass is necessary:

1. Put the stacks with a flat screwdriver and raise them a little.
2. Remove the side stacks, then the lower, and after it - the upper one.
3. Remove the glass from the window frame.
4. Clean glass, as well as planting for glasses in the frame from accumulated dirt with a spatula.
5. Wipe with a rag, degrease and dry.

Slack insulation

1. Along the perimeter of the frame, in the places of its joint with glass, to apply a sealant with a continuous line and, until it grabbed, insert the glass.
2. Fix the glass with stacks.
3. Remove the excess sealant from the glass after it is completely hardened.

Square of the wings

To determine the thickness of the seal, plasticine and plastic bag are needed. Plasticine is rolled in the shape of a tube with a diameter of about 2 cm, laid in a bag, after which it is placed in places of contact of the wings. The window closes, and after opening on the plasticine, dents are formed, corresponding to the depth of the gap. In this case, the thickness of the seal is taken accordingly the largest thickness of plasticine.

The process of insulation of the wings:

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

The insulation of old windows with a similar method is carried out both from the inner and outside.

Window insulation according to Swedish technology

Despite the name, the Swedish technology of insulation of wooden windows is very similar to the above technology of insulation of wooden windows, especially in terms of preparatory work, as well as insulation of glasses in the frame through sealant. A distinctive feature of the Swedish window insulation is the groove fastening of the special eurostrip seal, although ERDM is quite suitable instead of it.

For insulation of windows according to Swedish technology, it is necessary:

• by means of milling tools around the entire perimeter, the sash is to make grooves with a depth of 0.5 cm, and 2-3 mm wide enough. In this case, from the place of fastening of the loops, it is necessary to retreat to the side by 1-1.5 cm;
• lay the seal in the groove, placing it with a tail down;
• for better fixation, roll the seal in the groove using a special video;
• hang the wings and adjust the fittings.

Despite the simplicity of the Swedish technology of window insulation, the prices for such a service are only 3-4 times lower than the cost of a new plastic glass packet. Therefore, if the windows are already in order to have a scheduled and will stand for no more than 1-2 years, then it is worth looking for a cheaper insulation option with a short operational period.

Plastic window insulation technology

Work on the insulation of plastic windows is somewhat different from the work related to the sealing of wooden windows and include:

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

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

Replacing a rubber seal is made as follows:

1. Picking up the edge of the heading with a knife or a special spatula and, gradually lifting, remove it around the perimeter of the sash.
2. Take out the double -glazed window.
3. Remove the old seal by cleaning the grooves from the remaining elements of rubber and dirt.
4. Insert a new sealant by joining the ends of the rubber inside the groove.
5. Install a double -glazed window and fix it with glazing pounds by means of an mounting hammer.
6. Adjust the furniture of the sash.

As an additional measure of insulation of PVC windows, it is necessary to smear with the sealant of the joints of the frame, as well as the slopes with the windowsill.

Insulation of attic windows

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

The installation under the windows of the attic type of heating devices will not hurt, so the slopes will warm up, and condensate is unlikely to appear.

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

Thus, the price can also differ significantly for various methods of window insulation, folding under the influence of the cost of consumables and work performed. However, all technologies are so simple that window insulation can be done with your own hands without resorting to the services of professionals.
