Special silicone window seals for UPVC windows

Advantages of our special silicone window seals

Often only millimeters are missing!

We have developed our special seals made of high-quality silicone especially for this problem. They are not off-the-peg gaskets, but have been specially developed for the problem of retrofitting window gaskets to older UPVC windows. The profile geometry was selected so that our silicone window seals can be used as sash or frame seals by almost all leading system providers of UPVC windows in Europe.

Excellent resilience, up to 9 mm adjustment range, low closing pressure and the hollow chamber profile design for improved sound insulation are enormous advantages over standard EPDM window seals "at no extra cost". In the information section, you can see which seal you need under the topic "Three ways to your seal".

General information about silicone seals

Silicone seals are used to seal wooden doors and windows, among other things, and are rarely used in the manufacture of building elements in the industry for cost reasons. Rubber seals made from various materials, such as EPDM or ATPK, are often used here. Over time, rubber seals become hard and brittle due to sunlight, ageing or environmental influences.

The properties of a window seal are thus lost. There are good reasons for choosing silicone rubber as the material for our special window seals. Silicone seals are resistant to weathering, such as strong sunlight, ozone, light, atmospheric pollution and ageing. They remain elastic, colorfast and dimensionally stable in the long term.

They also remain intact when compressed or bent and therefore provide an optimum seal for all surfaces. They are maintenance-free and have an extremely long service life. Another plus point for choosing silicone seals is their durability, even at extreme temperatures.

In a range from 250°C to -60°C, they neither crack nor harden. Plastic or rubber seals, on the other hand, harden at low temperatures. Silicone seals also do not stick together, but retain their positive properties and consistency.

They therefore retain their elasticity and thus achieve the desired protection against noise, dust and water, while at the same time providing insulation against heat loss and thus actively saving some of the heating costs incurred.

Window seals between the window sash and frame are intended to prevent condensation, as condensation can be a cause of mold.
