What makes ASCENT uPVC superior?
Ascent uPVC product is free from lead (Pb) and other hazardous substances, and approved for green building concept. The profiles we use are designed for Indian tropical conditions and are extruded and tested conforming to BS Enu6o8. Systems are designed and developed for a wide range of glass sizes varying from 4mm to 36mm. They are a superior substitute for conventional wooden frames taking into account the cost, strength, beauty, precision, and ecology. Doors & Windows made of an engineered profile system; don’t let Heat, Cold, Sound, and Dust enter your home.
