Modern technology insulation windows

In place of the old and rather time-consuming methods of thermal insulation of windows for the winter were completely new materials and methods by which not only significantly reduced heat loss, but also accelerated the sealing process itself.In addition, the technology works with modern materials is so simple that it is allows to produce thermal insulation of windows with their hands.

materials for insulation, their purpose

Newspapers, wool, rags and other materialsinsulation windows thing of the past, and they were replaced by various types of gaskets and sealants.

quality seal provides a snug fit to the wooden casement or plastic window frame.Thus in plastic boxes also serves to seal the sealing glass in the frame.

In most cases, the sealant used as an auxiliary material, contributing to the elimination of gaps between the frame and sill slopes.However, wooden windows through hermetic glass provided tighter fit to the frame.

Thus, by combining in the insulation of windows and sealing gasket can reduce heat loss up to 90%.

Types of window seals, their characteristics

Modern seals are manufactured by extrusion of synthetic rubber with a variety of polymers.However, because of all the variety of sealants to seal windows are most often used:

1. EPDM - rubber seal, the main element of which acts EPDM.Colours EPDM-seal depends on the quantity added of the carbon black material largely influences the strength of the product.In this connection, the rubber seal is only available in black and gray.Thus gray seals are much more expensive than black, although slightly inferior to them on some quality indicators.

Pros:

• excellent moisture resistance;
• low compression set;
• high levels of weather resistance;
• excellent sound and thermal insulation properties;
• high UV resistance;
• small radius of curvature;
• resistance to mechanical damage;
• formed dense enough angle while continuously pulling;
• high strength and elasticity of the material is maintained throughout the operational period;
• durability.

Cons:

• seal swelling under the influence of the vegetable and mineral oils;
• non-weldable seal;
• high cost.

2. TPE or TPE - thermoplastic elastomer formed as a result of a mixture of rubber with polyvinyl chloride.Modified polyvinyl chloride has a homogeneous structure, so the low temperature seal coarsens, and at high - softens, which adversely affects the elasticity of the material.Thus during operation TEP does not emit any toxic elements and are not subjected to combustion, indicating a high safety insulation.

Advantages:

• wide range of colors;
• opportunity welding seams in the corners of the profile;
• resistance to chemicals in the form of alkalis, acids;
• small radius of curvature;
• no odor;
• low cost.

Disadvantages:

• small mechanical strength;
• tight corners formed by the welding material;
• high enough residual deformation;
• relative resistance to the sun's rays;
• low elasticity;
• operation period does not exceed 2 years.

TPN is a kind of TPE, as produced by foaming a thermoplastic elastomer.A distinctive feature of the SCC regarding the TPE - heterogeneous structure represented isolated from each other cells, through which SCC has higher rates of heat and sound insulation.

3. SiO - silicone sealant, belonging to the category of special-purpose rubbers.In regard to the strength and elasticity SiO considerably surpasses EPDM and TPE seals.Additionally, silicone sealant can be completely painted, since its properties is not reflected.

Advantages:

• resistance to sudden temperature changes;
• no permanent deformation;
• chemical resistance to aggressive media;
• does not change the properties under ultraviolet light;
• excellent water resistance;
• a high level of weather resistance;
• a long service life.

Disadvantages:

• slight mechanical resistance;
• high price.

Regardless of the merits and demerits of seals still differ on way of installation:

• adhesive - presented silicone, rubber, thermoplastic and foam seals, one side of which has an adhesive base.Such seals are distinguished by simplicity and speed of installation, but also the fragility.

• Slot - not suitable for bonding.To fix the heater you need to do a recess in which is laid a tubular seal made of silicone, rubber or thermoplastic elastomer.For a more lasting fit insulation rolled special roller.

• Adhesive - have no adhesive, so these seals are fixed on the surface by special glue or silicone sealant.By type of adhesive seals are rubber and silicone insulation.

Thus, EPDM seals considerably exceeds the TIC in many respects, giving at the same time the price of SiO, and thus occupies a leading position among the different types of seals.

sealant types, their characteristics

Despite the huge product range of different kinds of sealant, for thermal insulation of windows used only 3 species:

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

• acetate - havehigh strength and excellent adhesion, advantageously with smooth materials.However, the treated surfaces should have a high resistance to acetic acid released during the drying sealant.In addition, working with silicone sealant such as acetate must be carried out in a ventilated room because of persistent smell of vinegar, continuing until the curing of the sealant;

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

In general, silicone sealants have the following advantages:

• excellent elasticity;
• resistance to different temperatures;
• no shrinkage;
• do not change the original color over the entire lifetime;
• resistance to many corrosive environments;
• durability;
• reasonable cost.

Cons:

• not subject to staining.

2. Polyurethane sealants based on polyurethane resins, subject to further polymerization under the influence of moisture in the air.Suitable for insulation of plastic windows and insulation for the timber.

Pros:

• excellent heat resistance;
• high levels of moisture resistance;
• opportunity staining after complete solidification;
• with heavy vibrations are not deformed;
• resistance to most acids, oils;
• high elasticity;
• duration of operation.

Cons:

• during vulcanization emit corrosive substances;
• high price.

3. Acrylic sealants, based on manufacturing which are acrylic polymers and water, are the best choice for the closing of the fixed and immobile joints.

Pros:

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

Cons:

• opportunity shrinkage;
• low elasticity;
• possible deformation of joints;
• attract dust;
• yellowing over time;
• short lifespan.

Thus, when selecting a sealant special attention should be paid to their disadvantages, which to a large extent depend on the conditions of future exploitation.

Technology insulation wooden windows

warming process of both new and old wooden windows is quite time-consuming, so involves several steps.

Preparation frames

preparation process includes the following working order:

1. Remove the window sash.
2. Inspect the integrity of the sash, and if damaged - remove them.
3. Remove old paint from the frame by means of a spatula or other available tools and instruments.
4. Wipe the frame with a damp cloth, removing shelled paint and dust.
5. Clean, dry thoroughly.

Preparation glass

To improve the adhesion of the sealant to the frame and the glass must be:

1. Pry glazing beads flat screwdriver and slightly raise them.
2. Remove the side glazing beads, and then - the lower, and after him - the top.
3. Remove glass from the window frame.
4. Clear glass, as well as the landing place for the glass in the frame from the accumulated dirt with a spatula.
5. Wipe cloth, degrease and dry.

Winterizing windows

1. On the perimeter of the frame, at the point of junction with the glass, a continuous line and apply sealant until it hardens, insert the glass.
2. Secure the glass using glazing beads.
3. Remove excess sealant from the glass after its complete hardening.

Warming flaps

To determine the thickness of the seal will need clay and a plastic bag.Plasticine rolled into the shape of a tube with a diameter of about 2 cm, is placed in a bag, and then placed at the point where the valves.The window closes, and after opening on the plasticine will form dents corresponding to the depth of the slot.In this case the thickness of the seal is taken, respectively, the highest thickness of clay.

process insulation flaps:

1. Apply sealant, not pulling, to the place of its future location and cut into appropriate lengths at 45 ° C.
2. Gradually remove the protective paper from the self-adhesive seal glue it to the leaf.If
3. gasket has adhesive basis, then the first flap applied on the adhesive or sealant, which is then stacked on the sealing strip.
4. to secure the seal at the end of the work necessary to close the window and open it during the day.

Warming old windows in this method is produced both inside and outside.

Winterizing windows on the Swedish technology

Despite the name, the Swedish technology insulation of wooden windows is very similar to the above-described technology insulation of wooden windows, particularly in terms of preparatory work, as well as insulation glass in the frame by the sealant.A distinctive feature of the Swedish heat insulation of windows is a special seal mounting grooves eurostrip, although his place is fine and EPDM.

For insulation of windows on the Swedish technology is necessary: ​​

• through the milling tool around the perimeter of the valves to make grooves depth of 0.5 cm and a width of 2-3 mm is sufficient.This loop-mounting space is needed to step aside in the 1-1.5 cm;
• lay the seal into the groove, placing his tail down;
• for better fixation of the seal to roll in the groove with a special roller;
• hang leaf and adjust the fittings.

Despite the simplicity of Swedish thermal insulation of windows technology, the price of such a service is only 3-4 times lower than the cost of a new plastic windows.Therefore, if the windows are already rather worn out and stand for no more than 1-2 years, you should look for a cheaper option of warming with a small performance for the period.

technology insulation of windows from plastic

Insulationworks plastic windows are slightly different from the work associated with sealing wooden windows and include:

• periodic adjustment of the accessories, at least 1 time per year;

• replacement seals with the appearance of them even minor cracks, signaling the loss of all or part of the elasticity.

Replacing the rubber seal is made so:

1. pick up a knife or spatula special bead edge and gradually lifting, remove it on the sash perimeter.
2. Remove the glazing.
3. Remove the old seal, clearing grooves of the remaining elements of rubber and dirt.
4. Insert the new seal, the ends of the rubber dock inside the slot.
5. Set glazing and glazing beads to fix it by mounting a hammer.
6. Adjust sash fittings.

As a further measure of insulation pvc windows need to lubricate hermetic space frame joints, as well as slopes with a window sill.

Winterizing skylights

In most cases, problems with the integrity of roof windows appear in both the lower and upper slopes.Therefore, at the first appearance of drafts or frost is necessary to insulate the trouble spots with the help of a basalt or glass.

not interfere, and Installation of mansard windows, heaters, so will warm up the slopes, and the condensate is unlikely to emerge.

However slots can not be used to eliminate the foam core, since during expansion it can affect the offset of the frame relative to the frame, whereby the new cold bridges are formed.

Thus, the different ways of warming windows price can also vary considerably, folding under the influence of the cost of supplies and work performed.However, the technology is so simple that the insulation of windows is quite possible to implement your own hands, without resorting to the services of professionals.

And finally, one more simple way to insulation of windows, which look the video below:
