Raw Material

The seals, which are one of the most significant components for heating and sound insulation on PVC window systems and manufactured at our own plants, are made of EPDM (Ethylene Propylene Diene Monomer) as raw material. EPDM seal is the single seal that assures sealing in the longest time and it can be used without any problem for long years as it has a very high irreversible deformation rate.
