Its low thermal conductivity allows specified thermal performance targets to be achieved with minimal thickness of insulation ensuring your home is well insulated.

A 600mm by 1200mm board covering 0.72m2



With thermal conductivity as low as 0.020W/m.K rigid phenolic insulation is the most thermally efficient insulation product commonly available;

Phenolic insulation is manufactured by a process in which a plastic foam forms an insulating core between two flexible tissue faced layers. It has a high closed cell content and fine cell structure.

Wetherby recommend Phenolic boards are always kept dry, should you choose to use this thermal board with any thin coat render systems you must also fully bed the boards using Wetherby bedding adhesive as well as your usual mechanical fixing method.
