AA®3720 Folding/Sliding Door

Introduction

The AA®3720 Folding/Sliding Door is a solution for projects that demand the highest levels of thermal and weathering performance at a competitive price.

The AA®3720 uses advanced thermal break technology, ensuring thermal efficiency and full compliance with Approved Document L. The polyamide thermal break allows for single and dual colour options. The use of extruded gasket profiles and drain and ventilate strategy enable the system to achieve its weathering performance. The AA®3720 provides a door with market leading capabilities, equally suited to the discerning home owner or installed in commercial premises that wish to enhance their environment.

Our product development team focused on market demands to produce a door with high performance and innovation offering:

• Aesthetic Appeal
• Especially Slim Sightlines
• Simplified Fabrication
• Patented Features

Product Features and Benefits

• Highly insulated profiles with U_f-values  as low as 1.8 W/m²K for frame/vent combinations - uw-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 1200mm(W) & 2930mm(H)** - 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

** Dependant upon glass size and weight

Construction

Weathering is achieved by the use of EPDM gaskets and woolpile. The door is designed to be pressure equalised and fully drained.

Security*

The AA®3720 Folding/Sliding Door has been independently tested to PAS 24:2016.

* Does not refer to standard hardware, security hardware required

Weather Performance

Independently Weather Performance Tested to BS 6375-1:2015:
Air Infiltration (BS EN 12207:2000): Class 3 (600 Pa)
Watertightness (BS EN 12208:2000): Class E750 (750 Pa)

Wind Resistance (BS EN 12210:2000): Class A5 (1600 Pa)
Details of the Kawneer product tests are available from the Technical Services Department at Runcorn.
All Windows comply with Operation and Strength Test BS6375 Pt2:2015.

Enhanced Thermal Option

The addition of simple thermal shields divides the thermal chambers further to improve the thermal performance with minimal additional cost or fabrication. Enhancements of 0.1 W/m²K are possible with this addition.
