In addition to this, the steel reinforcement inside the profiles and the fact that all VEKA systems are extruded following the most restrictive quality standards, energetic class A exclusively (according to SR EN 12608), assure for the windows and doors excellent functionality and great durability.
Slightly rounded contours give the SOFTLINE 70 system its classic look. The smooth surfaces of SOFTLINE 70's high quality profiles remain attractive for many years, they are easy to clean and never need to be painted.
Best thermal insulation for each window (of up to Uw = 0,88 W/m2K), keeps heat loss to an absolute minimum. The 5-chamber technology of VEKA SOFTLINE 70 profiles reduces energy consumption and keeps your heating costs low.
High quality gaskets, EPDM, in elegant grey, black or ocher. The twin seal gaskets reliably keeps cold, draughts and damp at bay. The extremely reliable gaskets is a high-performance barrier against cold and draughts.
Galvanized metal reinforcement in accordance with VEKA reinforcement guidelines guarantee stability and long-lasting functionality.
Even standard windows made with SOFTLINE 70 profiles significantly reduce external noise and are upgradeable to conform to the lowest sound transmission class.
Special fittings, security glazing and handles can be fitted according to customer requirements to make SOFTLINE 70 profiles burglary resistant.
