Ultitherm - Underfloor heating board

Koskisen Oy, in co-operation with Uponor, has developed the Ultitherm underfloor heating chipboard which enables easy installation of water-circulated heating systems in wooden ground floor and intermediate floor structures. The new system is based on the water-circulated heating system with 20 mm pipes supplied by Uponor and Koskisen’s 30 mm-thick, grooved floorboards.

Ultitherm floor heating board enables savings both in material costs and installation time. The board is quick and easy to install and uses no extra adhesive substances, meaning no drying time. The ready-to-use board is supplied cut-to-size and the final floor can, depending on the material, be installed directly over a plaster or structural board covering the piping.
