Cladshield Details•••••••••• GENERAL Cladshield is a high performance breather membrane designed primarily for the use in lightweight industrial roofing and wall systems. The high water vapour permeability of Cladshield when tested to BS 3177 is 1100g/m2 /24 hours, making the material the ideal choice for high specification industry roofing and cladding. Cladshield controls the escape of water vapour from the roof and cladding structure whilst increased water resistance prevents the ingress of rain or moisture, providing a permanent high performance breather membrane. Exclusively developed and produced for The A. Proctor Group to carefully determined specifications by Britain’s only spunbonded fabric manufacturer, Don and Low Nonwovens Ltd , Forfar, Scotland.
