Tenapors Termo Compact EPS150 board for underfloor water heating

Tenapors Termo Compact are expanded polystyrene (EPS150) boards for underfloor water heating. The top of the boards has a profiled surface into which heating pipes with a diameter of 14–17 mm are easily pressed; the pipes can be bent into various layout patterns and placed at a spacing of, for example, 5, 10, 15, 20 or 25 cm.

Key features

• A polymer coating reduces the effect of moisture while the floor is being concreted; long-term water absorption ≤ 5 %
• Half-lap or interlocking edges reduce heat loss at the joints
• Thermal conductivity λD 0.034 W/mK; insulation layer thickness 20 mm, total thickness 42 mm
• Size 800×1400 mm, 10 boards per pack – 11.2 m²
• Very light, easy to install and place no significant load on the building structures
• Chemically resistant to weak alkali, acid and salt solutions

Where to use

For installing underfloor water heating, including in damp and wet floor constructions. With Tenapors Termo boards, a floor vapour barrier can be omitted, and they can be left uncovered on site for a short time.
