SUNFLEX SF75eco Bifold Doors

Aluminium glazed bifold doors which have been specifically designed to offer the best in thermal efficiency – an extremely low U-Value, eco-friendly folding door system.

A unique bifold door system, specifically designed to accommodate a triple glazed sealed unit. The advanced engineering and clever technology enables the system to perform to the highest levels of thermal efficiency, as well as maintaining the stunning visual appearance, slim sight lines and configuration options of the award-winning SF55s.

Features and benefits:

• Designed with more than 35 years of folding door experience.
• Advanced thermal performance (U-value from 0.8 W/m²K†) with unrivalled weather performance (900 Pa water tightness* and 600 Pa air permeability*) to severe weather rating standards.
• Ultra-slim 115 mm sightlines and 75 mm frame depths designed to accommodate a triple-glazed unit. Panels sizes up to 1200 mm wide and up to 3500 mm high with a choice of either low-threshold or fully weathered tracks. Can be used to create open corners with integrated moveable corner post.
• Manufactured with multi-point locking to meet the requirements of PAS 24:2016 and Secured by Design’s police preferred specification for security.
• Unique panel catch holds first door in place whilst exclusive stacking clip technology secures system when doors are fully opened. Unique part-vent position allows for doors to provide ventilation without having to be opened.
• Locking panel catch holds the lead door of the system in place when the doors are being opened, preventing the door from swinging shut.
• Stacking clip holds the doors securely in place when they are stacked open, stopping the wind (or young children) closing the doors unexpectedly.
• Patented 44 mm multi-chambered polyamide thermal break.

* Water tightness and air permeability test performance is dependent upon a number of factors including system configuration and panel sizes.

† Thermal performance achieved is dependent on glass specification.
