Key Features
High-Quality Construction:
Tekwarm Overlay MR-MDF boards are manufactured from Tongue & Groove moisture-resistant MDF, identified by its green tint core appearance. This ensures excellent durability and performance in interior humid conditions.
Dimensions:
Each board measures 1200mm x 600mm x 9mm, featuring tongue and grooves on all edges for easy and seamless fitting.
Compliant and Reliable:
Tekwarm Overlay MR-MDF boards are manufactured in accordance with EN 622-5, guaranteeing the highest standards of quality and safety.
Ideal for Tiling:
When tiling over the overlay board, simply follow the tile manufacturer's instructions, utilizing an S1 Tile adhesive and a decoupling membrane in conjunction with the board for optimal results.
Easy Installation:
The boards should be fitted in a brick bond pattern at a 90-degree orientation to the direction of the UFH boards, with glued T&G joints. Mechanical fixing should be done with suitable screws at maximum 300mm centres.
