Garnalex has launched Sheerline Prestige. The new system features a full depth Eurogroove which means it will accept PVC-U hardware.

The Prestige system includes windows, doors and French doors and is available in the same style options and 12 stocked colours as Classic, Sheerline’s ultra slim window system. Prestige also includes 28-44mm glazing options and a choice of small, intermediate and large outer frames to accommodate different plaster lines and window reveals.


 “The launch of Sheerline Prestige is timely. The market remains strong and consumer demand for high performance, beautiful products is soaring.”

– Roger Hartshorn 

CEO, Garnalex



Built around Sheerline’s Thermavic multi-chamber, thermal design means that U-Values are as low as 0.9 W/(m2K) for triple glazing and 1.3 U-value W/(m²K) double glazed are possible.



Sheerline’s sills feature this same technology coupled with in-built weather sealing. Prestige also incorporates Sheerline’s patented corner jointing method, making it easy and quick to fabricate perfect corners.


Most versatile

“Sheerline is perfectly poised to help fabricators and installers benefit from demand,” continues Hartshorn. “Our first system, Sheerline Classic, is a super-slim specialist window, ideal for replacing traditional steel-framed windows. Our second system, Sheerline Prestige is our most versatile system to produce good looking windows, doors and French doors. There is a choice of sizes and designs to suit any type of property. The feedback from fabricators has been extremely positive and we’re excited about the year ahead.”
