Duo Overlay Under Carpet and Vinyl Heating Protective Cover

Allows the installer to fit a suitable vinyl. Please see our under vinyl heating guides for types of suitable vinyl flooring. Laid directly over the foil without the need for any other additional protective layers. Constructed from 2 x 3mm boards. The two layers are staggered so no joints align and are held together with a high adhesion double-sided tape. Tape is supplied with the duo overlay boards. Furthermore, the boards are laid directly over the heating system. And once fitted they protect the heating below. And provide a hard smooth layer ready for the flooring to be fitted over.
