AA®3720 Folding Sliding Door

Application

A solution for projects that demand the highest levels of thermal and weathering performance.

Description

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.
  • Stainless steel rollers for smooth and effortless operation.
  • Choice of threshold options – continuity between internal and external spaces. Rebated, low and sunken track options to add further design capability.
  • Innovative design features – patented technology, providing premium product performance.
  • Suites with the AA®720 Window Series – total design flexibility offering total project solutions.
