Finnish underfloor-heating chipboard that is easy and quick to install

KoskiTherm is an uncoated, pre-grooved and tongued-and-grooved chipboard for the easy installation of water-circulating floor-heating systems in wooden ground floors and intermediate floors. The system is based on floor-heating panels that are made of chipboard and which are equipped with grooves to accommodate floor-heating pipes measuring either 22 mm or 16–17 mm in diameter.

Savings in installation time and costs thanks to floor-heating boards

KoskiTherm floor-heating boards save in material costs and installation time. The floor-heating panels are quick and easy to install on top of ground floors and intermediate floors, and after their installation, the floor is immediately ready for the next work phase or construction platform. In some cases, the final floor can be installed directly on the panels.

An energy-efficient floor-heating system

KoskiTherm floor-heating boards are designed to ensure maximum thermal efficiency while minimising heat loss, and they also result in lower energy consumption. Not only are they quick to install, the floor heating panels made from energy-efficient chipboard also help save in heating costs.

Clean chipboard won’t damage saw blades

KoskiTherm chipboard is made in Järvelä, home to the only chipboard mill in Finland, by professionals who ensure a high-quality end product using clean raw materials. Sawmilling industry wood by-products account for 90% of the content of all the boards. Sand and other heavy impurities are efficiently removed from the raw material before the chipboard is produced, guaranteeing a board that is clean and consistent in quality. The boards can be sawn, drilled and cut using any conventional woodworking tools, as high-quality chipboard is easy to machine and won’t damage saw blades. Blades that are in good condition cut board better and bring savings in equipment maintenance.
