Frequently Asked Questions About Aluminium Bi-Fold Doors.
Get expert guidance on specifications, thermal efficiency, and configurations.
Aluminium provides superior structural strength compared to uPVC. It will not warp, flex, or twist under thermal expansion, allowing for significantly slimmer frame sightlines, larger glass panels, and seamless long-term roller operation.
Our aluminium bi-fold systems feature integrated polyamide thermal breaks combined with high-performance double or triple glazing, achieving U-values as low as 0.12 W/m²K to comfortably surpass modern UK Building Regulations.
We offer configurations ranging from 2 to 7 panels opening inwards or outwards, with single traffic door options for everyday access. Frames can be durable powder-coated in any RAL colour, including Anthracite Grey, Black, and White.
Every door set features high-security multi-point shootbolt locking systems, anti-snap key cylinders, internally glazed bead structures, and robust hardware tested to PAS 24 security standards.
