Combymat Overlay Boards. Allow use of combymat heating mats beneath carpet and vinyl floors
Combymat Overlay Boards are pre-coated with adhesive and allow the Combymat heating system to be installed beneath carpet, vinyl, linoleum and bonded board floors, without needing to cover the heating system with a levelling compound. The Overlay Boards provide a strong, stable and smooth floating sub-floor.
By enabling a dry installation without any wet trade the system saves installation time and costs and also minimises build height; the total build height of the Combymat System with underlay, and the Overlay Boards, is only 13mm. Carpets can be fitted the same day as the Overlay Board installation is completed, any other floor surfaces must be fitted between 24-48 hours after laying the boards.
Each pack of boards covers 2.88m² and for rooms below 10m² we recommend supplying boards to cover at least 15% more than the room area to allow for off-cuts.
For rooms above 10m² we recommend ordering boards to cover 10% more than the room area, but for particularly complicated shaped rooms we recommend 15% more than the room area.
