AA®3720 Folding Sliding Door

The AA®3720 Folding/ Sliding Door is a solution for projects that demand the highest levels of thermal and weathering performance. The product uses advanced thermal break technology, ensuring thermal efficiency and full compliance with Building Regulations (E&W) Approved Document L. The polyamide thermal break allows for single and dual colour options. The use of extruded gasket profiles, and a drain and ventilate strategy, enable the system to achieve its weathering performance.

Features and benefits:

• Highly insulated profiles with U-values as low as 1.8 W/m²K for frame/ vent combinations; U-values as low as 1.0 W/m²K at the maximum panel size (using 0.7 W/m²K triple glazing and warm edge technology).
• A range of door configurations in either open-in or open-out stack variants – total flexibility for all project applications.
• Panel sizes up to 1200 x 2930 mm (w x h), dependent upon glass size and weight. Can achieve solutions in the most demanding of applications.
• Slim sightlines – no floating mullions. Reduced metal content and increased fabrication efficiency.
