Traditionally, windows open by swinging inward or outward, requiring clear floor space and limiting furniture placement. In compact apartments, offices, or crowded interiors, this can reduce usable space and disrupt layout flexibility.
The latest aluminium alloy sliding window systems address this limitation by opening sideways along a track, eliminating the need for indoor clearance. This design innovation allows interiors to remain fully functional while providing wide, unobstructed views.
Constructed from 6063 – T5 or T6 aluminium, these systems combine lightweight strength, corrosion resistance, and long-term durability. Stainless steel sliding tracks enable smooth, reliable operation, even for larger panels.
Thermal performance is enhanced with polyamide (PA66) thermal breaks, typically 24 mm wide, and EPDM gaskets ensure airtightness and water resistance. Frame thermal transmittance (Uf) in verified systems ranges from 3.1 to 5.1 W/(m²·K), while glazing up to 44 mm improves sound and heat insulation. 
Certified to EN 14351 – 1, aluminium alloy sliding windows combine verified materials, proven performance, and sideways operation to deliver a practical, space-saving solution for modern residential and commercial interiors.
