Technical Excellence & Performance
Engineered for energy efficiency and durability, the GS20 sliding door offers excellent insulation and weather performance. The thermally broken aluminium profiles ensure minimal heat transfer, achieving U-values as low as 1.4 W/m²K, depending on glazing selection and meeting Building Regulations for new build or refurbishment projects.
The GS20 keeps your home dry and cosy, with rigorous weather testing. Its acoustic insulation performance reaches up to Rw 41dB, providing an effective barrier against external noise.
Designed for smooth and effortless operation, the GS20 utilises precision-engineered stainless steel rollers running on a high-quality steel track. This ensures consistent performance and longevity, even with large panel sizes. The system supports panel widths up to 2500mm and heights up to 3000mm, with a maximum weight of 320kg per panel.
A unique drainage system is integrated into the bottom track to expel water efficiently while maintaining the sleek flush threshold giving you seamless internal flooring and external decking or slabs. This feature ensures long-term weather protection, reducing the risk of water ingress and enhancing overall durability.
