Sealing rubber on the plastic windows will keep the coziness in the apartment

Modern plastic windows are beautiful and stylish. They reliably protect the room from drafts, keep the heat inside the apartment. This is largely due to the sealing rubber on the plastic windows.

It allows you to:

• Ensure tightness;
• Smoothly open the window;
• Protect the contacting parts from damage;
• Adjust the clamp pressure;
• Ensure the safety of windows.

Main types of rubber seals

• Synthetic rubber (EPDM).
• Thermoplastic elastomer (TPE).
• Silicone gaskets.
• Rubber.

Rubber rubber EPDM has a longer service life (10 years against 4-5 for plastic), but it is more expensive than TPE and has only two colors: gray and black. While the plastic can be painted in any desired color. The tensile strength of synthetic rubber is more than one and a half times, for a break - up to 4 times.

Where to install sealing rubber for plastic windows

• On the inner and outer sides of the leaf along its perimeter.
• On both sides of the double-glazed windows.

The grooves for the seal are in the profile of the frame and leaf. Rubber should fit tightly into the profile groove. The sealant has a mushroom protrusion. He sits in the groove so tightly that pulling it by hand is very difficult.

Sealing rubber has a different thickness and cross section. So, the rubber of the Turkish company "Sechil Kauchuk" has 16 different types.

Sealing rubber on plastic windows made of artificial rubber has the following properties:

• Maintains its qualities in the temperature range from -50 to +80 degrees Celsius;
• Do not be afraid of exposure to moisture, acids, chemicals, ultraviolet, solvents, alkalis;
• Retains tensile strength (quickly returns to its original position) and deformation;
• Protects from noise and dust;
• Suitable for most plastic windows systems.

Seal maintenance

No matter how good a window is, it needs to carry out saving activities. Special care requires a rubber band on the plastic windows (photo). It is necessary:

• Clean from dust outside and inside of objects that fall under the rubber.
• Lubricate with special silicone.
• If oil and grease of any origin get in the rubber band on the plastic windows swells. To prevent this problem, manufacturers lubricate it with a means containing glycerin. You can treat the sealant once a year for prevention.
• Rubber rubber of black color leaves traces on white plastic because of the presence of soot in them (it increases the strength of the sealant). They are removed with a detergent.

Replacing the obsolete sealant

If a low-quality sealant was installed in the manufacture of a plastic window, then eventually it begins to break down: it cracks, splits and breaks up into pieces and dust. This leads to depressurization of the window. As a result, noise, moisture, cold air penetrate into the room. The double-glazed window can fall out of the window, injuring the hosts or random passers-by.

Change the rubber if:

• In winter the corners of the glass unit freeze;
• Windows are blown along the perimeter of the leaf;
• The shutter is difficult to close;
• Rubber swells up, sticks, cracks, falls behind the glass unit or smells unpleasant.

Sealing rubber on plastic windows varies according to this pattern:

• To pick up rubber of the necessary section and thickness.
• Remove old rubber, clean the grooves of dust and wash with detergent, wipe dry.
• Remove the glazing beads with a mounting shovel, pull out the double-glazed windows, remove the rubber residues.
• Manually turn the seal into the grooves of the profile along the perimeter of the leaf, without pulling or forming hummocks.
• Finish the ends, first leaving the stock to 1 cm, then reduce them, cutting off excess.
• Install the sealant around the perimeter of the leaf, first top and bottom. Rubber in the corners to fix with glue.
• To get rubber in grooves under double-glazed windows. Cut all parts with a margin for drying out. Lateral install after the upper and lower.
• Install the double-glazed windows so that the seal does not tighten inwards.
• Fix the glazing beads using a PVC hammer.
• Adjust the opening of the leaflets, their clamping, tightness after repair.

Consistent implementation of all phases will allow the window to again become a reliable protection of your apartment.
