Jack Aluminium’s SD70 Heritage door has achieved PAS 24 testing on a large-format doorset measuring 2,100mm wide by 2,500mm high.

The test was carried out on a full-scale doorset representative of real project specifications, reflecting the growing demand for larger door sizes across residential and light commercial applications.

The latest PAS 24 result incorporates recent refinements to the SD70 system, including a bespoke hinge design developed by Jack Aluminium and updated hardware configurations. Importantly, these enhancements have been achieved while maintaining the slim sightlines required for heritage-style aesthetics.

According to Jack Aluminium, the results forms part of an ongoing programme of system development and independent testing, ensuring its products continue to meet evolving performance and compliance requirements.

The SD70 Heritage door is part of Jack Aluminium’s wider portfolio of aluminium systems designed for residential and commercial projects where both design and performance are key considerations.

With high-performance U-values from 1.3 W/m²K and versatile single or double door configurations, the SD70 Heritage Door is compatible with Jack Aluminium’s RD70, TW70, and SW60 systems.
