The CPD examines the different curtain walling options – ladder, stick, unitised and structural glazing and explains the differences between them and the most appropriate applications for each.

It also covers the key design criteria - from material, spans and fixings to finishes, glazing and ventilation; and there is a detailed focus on the load considerations which apply when calculating curtain walling designs.

Also part of the CPD is a guide to the regulations and standards governing the installation and performance of curtain walling with an overview of the rigorous testing regime required to achieve the CWCT approval required by the NHBC.

The new CPD is a key element in REHAU’s campaign to promote its REHAU Polytec 50 composite curtain walling system which is both CWCT approved and Passivhaus certified. The REHAU system combines the structural capabilities of steel reinforcement, the design and finish of aluminium on the exterior and the warmth and low maintenance benefits of PVC-U on the interior.
