Key Features
• It is assumed that this will result in a lower thermal bridge, and be more straight forward to air seal, than a design where the wall runs straight up to the roof liner, around all the purlins.
• Thermal bridging can be minimised by ensuring the liner and outer sheets never cut across the insulation layer.
• Cleader angles are required to provide support and air sealing between purlins. Joints must be structural and not interfere with seals. Fasteners, securing cleaders, must not interfere with liner seals.
• Many combinations of cladding and materials are possible, which would still achieve similar thermal bridge and air seal performance.
