Garnalex Launches Sheerline Prestige

by | Jan 21, 2021 | Trade News

Garnalex has launched Sheerline Prestige, its most versatile and thermally efficient aluminium window and door system. Featuring a full depth Eurogroove, Prestige lets fabricators use their existing PVC-U hardware to streamline manufacturing, and is set to help redefine installer expectations in 2021.

Garnalex says Prestige offers unrivalled choice and boasts one of the widest range of window styles and includes doors and French doors. The system 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 for a perfect finish for any size and style of home.

Prestige was developed from Sheerline’s core principles of beautiful aesthetics, top performance and innovative, fabricator and installer-friendly design. Built around Sheerline’s innovative Thermavic® multi-chamber, thermal design, U-Values are as low as 0.9 W/(m²K) for triple glazing and 1.3 U-value W/(m²K) double glazed. Sheerline’s cills feature this same technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside. Prestige also incorporates Sheerline’s patented corner jointing method, making it easy and quick to fabricate beautiful, easily repeatable perfect corners, time and time again.

Roger Hartshorn, Garnalex CEO, comments: “The launch of Sheerline Prestige is timely. 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. 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 feedback from fabricators has been extremely positive and we’re excited about the year ahead.”

Sheerline Prestige’s product innovation is matched with outstanding service. All profiles and components are available in 5 working days in 12 stocked colours, including 3 anodised finishes. Dual colour combinations from this stocked range are available on the same 5-day turnaround. While bespoke colours are available in just 10 working days, setting new customer-friendly agile standards for aluminium.
