Corner-welded commercial door
3rd July 2018

Kawneer is claiming ‘the strongest aluminium door construction available’ with the launch of its corner-welded AA190 TB commercial entrance door.

The door has four separate weld points to each corner, each of which has a ‘lifetime guarantee’. Testing has verified its suitability for use in severe-duty applications as defined in BS 6375-2: 2009.

The system has Class 2 (300 Pa) air permeability, Class 3A (100 Pa) watertightness and Class C2 (800 Pa) wind resistance, results that are based on an open-in double door with butt hinges and rebated threshold. With security hardware, it meets Secured by Design criteria.

The door is designed to accept glass units up to 43mm thick, with a maximum leaf weight of 120kg with an overhead closer and a maximum of 200kg using the floor closer, all with leaf sizes up to 1320mm wide and 3000mm high.

The AA190 TB door also offers an achievable whole-door thermal transmittance of Uw = 1.7 W/m2K with a glass centre pane of Ug = 1.0 W/m2K.

It is offered with a finger guard pivot stile as standard, providing child-friendly reassurance, safeguarding against injury to fingers that might be accidentally caught between the hinge stile and frame.

Independently tested to PAS 24: 2016 for the enhanced security performance of single and double-leaf external doors, the enhanced security is available for both pivot and butt hung doors which can feature panic hardware. There is also a range of thresholds including drained low thresholds compliant with the Equality Act 2010.

The door is available with its own thermally broken framing system – 451PT, which suites with other Kawneer fenestration solutions.
