The Aluminium CS 77 external door is built on the same multi-chamber thermally broken profile that defines the CS 77 window system, ensuring seamless visual co-ordination between windows and doors across the building envelope at every scale from detached house to commercial development.
Fibreglass-reinforced polyamide thermal breaks and precision-engineered weather gaskets deliver consistently high levels of thermal insulation, air tightness, and weather resistance — meeting the requirements of UK building regulations and performing reliably in the full range of UK weather conditions throughout its service life. The casement door format provides a traditional outward-opening configuration in a contemporary aluminium engineering that suits the full range of residential and commercial building types.
Available in inward and outward opening configurations, with single and double door formats and matching sidelight and overhead light panels for fully integrated glazed elevations.
A comprehensive RAL colour range includes textured, anodised and dual colour options. Multi-point high-security locking and Secured by Design accreditation are standard, and smart access systems are available as an option. The CS 77 door profile co-ordinates directly with the CS 77 window system, the CF 77 Bi-fold and CP 130 Sliding systems for a consistent architectural language across the complete building envelope.
