Seal with a knot

That extra edge: silicone seals with anti-stretching-string

Maximum elasticity and flexibility, extreme temperature resistance: high-purity silicone rubber is a true all-rounder! GfA silicone seals go even further: like many of our other profiles, we equip them with the innovative GfA anti-stretching-string. It makes seal replacement even easier – and simply better. No longitudinal stretching during installation, no subsequent shrinkage. No gaps, no waste thanks to the stretch protection, which you can identify in our online shop by the suffix “CC” in the product number.

sealing frames

Ready to install and perfect: sealing frames

When installing seals in windows, precision is essential – otherwise leaky corners, drafts and moisture can occur and heat is lost. The solution, made by GfA: cleanly welded sealing frames for timber, timber-aluminium, aluminium and PVC windows. We cut with millimetre precision, weld the corners neatly and remove the welding seams – many small steps for one optimal result: windows that remain airtight for years! Your specialist advisor has all the information!
