TERRATERMAL STAR

Terratermal Star is an underfloor heating panel designed for spaces with minimum size and height standards, and larger compressive loads. Laying is easier due to a unique edge design. Plug design supports tubes with a diameter of 14 – 16 mm with 50mm spacing. It is installed under cement screed, supporting a load up to 3,000 kg/m2.
