Trusted profile brands
VEKA
Deutschland · Seit 1967
The standard that defines the European PVC industry. With Veka you don't choose between warmth, silence and durability — all three come as standard.
5 to 7 air chambers — each one retains heat and blocks cold from outside
Wide range — windows, doors and accessories for any project and style
RAL quality certificate — every batch independently verified in Germany
Steel reinforcement inside — the frame never bends or warps over the years
Up to 48 dB sound insulation — traffic, neighbours and city noise stays outside
Withstands −40 °C to +70 °C — no cracking or warping in any climate
CORTIZO
España · Galicia
Premium PVC made in Spain. A match for the world's best — and superior where it counts: engineered specifically for intense sun, heat and the Mediterranean coastal climate.
3 mm Class A wall thickness — the most rigid profile on the market, no warping for decades
Certified for coastal climate, extreme heat and strong coastal winds (Class S)
Colour that never yellows — 7 titanium dioxide layers protect the finish from sun
Class II impact resistance — withstands storms, hail and heavy mechanical knocks
Up to 46 dB sound insulation — traffic, neighbours and city noise stays outside
The choice of architects for villas, penthouses and exclusive European projects
