WETHERBY INTERNAL WALL INSULATION SYSTEMS
The Wetherby Internal Wall Insulation System, comprises a rigid phenolic (PF) board, faced with a perforated foil on one side and with an unperforated foil on the other. This is subsequently pre-bonded to a sheet of plasterboard during the manufacturing process.
These systems are for use as an insulated dry lining for solid or cavity masonry walls and the underside of timber or steel rafters in pitched roofs, in new and existing dwellings and buildings of similar occupancy.
Wetherby Internal Wall Insulation Board is installed using various adhesives and/or can be mechanically fixed, either directly onto the wall or onto the timber battens or metal furring (see the Installation part of this Certificate).
