Innovative and Versatile 

Sheerline Prestige allows light to flood in to open up interiors

Each Prestige installation is individually tailored to the exact requirements of your property.

Our versatile 72-80mm wide system is available in casement, French and fixed windows and has been designed to allow light to flood into your home, which has been achieved by using sashes as slim as 88mm.

Our patented construction method uses threaded screws to bind corners tightly together, this helps eliminate misaligned corner issues that can occur on ordinary aluminium frames.

Thermavic Technology

Keeping your home snug and warm

Our Sheerline Prestige windows combine clean lines with exceptional thermal performance for up to an A+ Window Energy Rating. The Thermavic multi-chamber thermal design, hidden away in each window and door, helps keep your home well insulated against the worst of the UK weather.

Sheerline Prestige achieves a U-value of 1.3 with double glazing, and 0.9 with triple glazing. The better insulated the window is, the lower the U-value will be.

Both styles are available in either our standard outer frame or as a ‘flush’ option that brings both the perimeter and the opening sash perfectly in line with each other.
