Outstanding technical performance, high quality of a classically shaped 6-chamber profile makes Veka Alphaline a standout window for the most demanding customers. Due to the exceptional thermal insulation Veka Alphaline is dedicated for passive buildings.

VEKA uPVC windows - class A profiles

All VEKA window profiles are classified according to PN-EN 12608 norm as the highest Class A. This classification confirms the thickness of the outer wall of the profiles of 3 mm (with a tolerance of 0.2 mm). Class A profiles perfectly protect against heat loss and noise and also increase the stability and durability of windows. According to the studies class A profile corners are 10-20% more resistant to damage.

Energy-efficient windows for passive buildings

Thick walls of robust 90mm, 6-chambers profile supported by triple-sealing made from high quality EPDM rubber and triple-glazed unit equipped with additional thermal breaks provide spectacular heat, sound and moisture insulation. In a basic variant Veka Alphaline achieves heat transfer coefficient of 1.1 W /m2*K. Thermal insulation performance can be increased by using the thickest available triple-glazed units and thermal breaks within frame and sash. Veka Alphaline windows are successfully used for passive buildings.

Triple-glazed windows

Triple-glazed, deep mounted unit provides efficient thermal and sound insulation. Available glazing units range from 24 to 50mm.

Solidity and security

Galvanized steel reinforcements with a thickness of 1.5-3 mm provide excellent stability of the windows and protection against burglary. High quality window hardware and deep mounting of glazing unit ensures that windows are extremely robust and resistant to weather and mechanical damage.

Elegant and functional windows

Classic shape of the profile with rounded edges of the frame and sash gives Veka Alphaline windows classic and elegant appearance. Wide range of  colours, availability of smooth and wood-like veneers and a wide range of accessories allow windows to have personal touch. Light gray, hardly visible gaskets match well with  classic look of the window.
