Alphaline 90

Modern uPVC windows manufactured using VEKA’s ALPHALINE 90 profile system significantly improve your house’s energy needs. Their 6-chamber format and 90-mm installation depth optimally exploit the insulating properties of air, providing you with superb heat insulation as standard.

Moreover, an optional insulating strip improves this performance even further – living up to even the very highest expectations. The result: pleasant room temperatures, regardless of the weather outside, and pleasantly surprising reductions in heating costs, too.

Equally convincing is the classical design, with smooth rounded contours that blend in with all kinds of building styles, from modernised older buildings through to ultra-modern architecture.
