14% thinner than our previous product, LowBoard 2® offers a build-up height of just 18mm for a fully encased underfloor heating system to lay over an existing insulated floor. The system is designed to deliver superior heating performance while keeping installation risk and construction height to a minimum. LowBoard 2® features two distinctive routed panels that perfectly align around the warm water pipe, providing a surface ready for the floor finish to be laid over.
