Garnalex has launched Sheerline Prestige, described as ‘its most versatile and thermally efficient aluminium window and door system’ featuring a full depth Eurogroove that lets fabricators use their existing PVC-U hardware to streamline manufacturing.

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

Built around Sheerline’s Thermavic multi-chamber, thermal design, the system offers U-Values are as low as 0.9 W/(m²K) for triple glazing and 1.3 U-value W/(m²K) double glazed. Its cills feature this same technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside.

Garnalex CEO Roger Hartshorn said: “Our first system, Sheerline Classic, is a super-slim specialist window, ideal for replacing traditional steel-framed windows or contemporary properties. Our second system, Sheerline Prestige is our most versatile system with beautiful looks, and doors and French doors, and a choice of sizes and designs to suit any type of property.”

“The market remains strong and consumer demand for high performance, beautiful products is soaring. Sheerline is perfectly poised to help fabricators and installers benefit from this demand.

All Prestige profiles and components are available in five working days in 12 stocked colours, including three anodised finishes. Dual colour combinations from this stocked range are available on the same five-day turnaround. Bespoke colours are available in 10 working days.
