A forward-thinking approach between Council for Aluminium in Building (CAB) members has led to the development of an innovative hardware system for Document L compliant aluminium patio doors.

The development of PSK LM sliding door hardware was driven by hardware manufacturer Siegenia-Aubi in conjunction with major aluminium systems companies faced with the challenge of producing the larger profile sections required to provide increased chamber depth for Document L compliance.

The new PSK LM system can carry sash weights of up to 150kg, which allows for a larger glass door surface area, and fits traditional aluminium eurogrooves. Another hardware option is also available for the increasingly popular PVC-U eurogrooves.

Alastair Wheeler, Siegenia-Aubi Technical Sales Manager, explains:

‘We instigated partnerships with profile manufacturers to develop a hardware solution that would work with their products. The result is high performance, Document L compliant patio doors for the new build and refurbishment sectors.’
