Material & Structure: Foam / EPDM Cellular Rubber

Depending on the version, high-quality foam grades are used; the black variant is specified as EPDM cellular rubber. EPDM foam is elastic, durable, and designed for changing environmental conditions – ideal when seals need to compress and recover repeatedly over time. In use, the material impresses with uniform pressure distribution, excellent recovery properties, and clean edges – the foundation for a reliable, precisely fitting seal.


Foam Seal Variants

Self-adhesive foam seals are available in grey, black, or white, each in 44 mm or 54 mm widths, with lengths of up to 10 m – precisely cut to size. The high-adhesion glue is designed to withstand large temperature fluctuations; the products are “Made in Germany.” This way, you combine quick installation with reliable hold – whether as narrow sealing strips, continuous frame solutions, or custom-sized cuts.

Application: Roof Windows, Doors, Technical Equipment

Roof window seals compatible with VELUX are particularly popular – suitable for wooden and plastic windows, ideal for example at the ventilation flap. For clean adhesion: remove the protective paper, position the seal, and press firmly; minor adjustments are possible. Before installation, remove the old seal and clean the surface (clean, dry, and grease-free). These instructions also apply to many door, window, and equipment applications where quick retrofitting is required.

Frequently Asked Questions

High-quality foam seals are used in this category; the black variant is specified as EPDM cellular rubber. EPDM foam is elastic, stable, and designed for changing environmental conditions – ideal for sealing windows, doors, and roof windows. Its cellular structure allows small surface irregularities to be compensated and ensures the seal maintains long-lasting contact.

You receive precision-cut pieces – the offered sealing strips are manufactured exactly to customer specifications. In this category, widths of 44 mm or 54 mm and lengths of up to 10 m are available; this allows efficient installation on individual sashes, complete frames, and special shapes. This minimizes waste and simplifies installation.

Yes. The seals are self-adhesive – remove the protective paper, position the seal, press firmly, and minor adjustments are possible. Proper preparation is important: remove the old seal and ensure the surface is clean, dry, and grease-free. This allows the temperature-resistant adhesive to achieve its full strength – even under changing roof climate conditions.

Yes, in this category you will find roof window seals compatible with VELUX, suitable for wooden and plastic windows, and optimized, for example, for the ventilation flap. This simplifies maintenance and retrofitting when existing seal profiles lose elasticity over the years. Custom manufacturing ensures that replacement is precise and perfectly fitting.

The high-adhesion glue is specially designed to withstand large temperature fluctuations – a particular advantage for roofs and façades. Combined with the suitable foam quality, it provides long-lasting sealing with uniform contact pressure. Made in Germany ensures consistent material and manufacturing quality.

The available colors are black, white, and grey. This allows the sealing strips to blend discreetly with frame and sash surfaces – visually subtle yet functionally strong. For visible areas (e.g., ventilation flaps), the right color is often crucial to achieve a cohesive overall appearance.
