Technical Excellence & Performance
Built for both aesthetics and durability, the GS15 sliding door meets the highest performance standards. The thermally broken aluminium profiles reduce heat transfer, ensuring outstanding energy efficiency. With U-values as low as 1.2 W/m²K, the system helps to maintain a comfortable indoor temperature throughout the year. These doors also comfortably meet current Building Regulations.
The GS15 also delivers superior acoustic performance, reducing external noise with sound insulation of up to Rw 41dB. Designed to withstand the elements, it achieves Class 4 air permeability, Class 7A water tightness, and Class C5 wind resistance. Security is a priority, with a robust multipoint locking system that features strong steel pins and a slim flip-lock mechanism. The handle is discreetly integrated into the design, maintaining the door’s streamlined appearance while ensuring ease of use.
The system accommodates double glazing from 26mm to 30mm and supports panel widths up to 2500mm and heights up to 3000mm, with a maximum panel weight of 320kg. Precision stainless steel rollers ensure smooth and effortless operation, even with large panels.
A unique drainage system is integrated into the bottom track, ensuring that the door remains weather-resistant while maintaining a flush threshold. This feature provides enhanced protection against water ingress, even in exposed locations.
