Thermal insulation plates

For quality and effectiveness of isolated foundations, walls, floors or roofs, TENAPORS materials are the best choice for all types of buildings, from private homes up production, public and educational buildings.



Thermal insulation sheets for heated floors

Foamed polystyrene sheets TENAPORS TERMO are an eco-friendly, inexpensive and efficient insulation material for quick laying of water-heated floors. The sheets are made of a porous material with closed pores and flame retardant additives (substances that suppress combustion). They are resistant to weak acidic, alkaline and saline solutions but non-resistant to aromatic and halogen containing solvents, esters, ketones, oils or lubricants (e.g. toluene, solvent, ethyl acetate, etilacetāts, acetone, etc.). One side of the sheets has cylindrical grooves for easy and fast arrangement and fastening of heating pipes. The sheets are intended for heating pipes in ∅ 16–18 mm. These sheets may be continuously used as a thermal insulation material at ambient temperatures of up to + 80°C.

 Arrangement of water-heated floors using TENAPORS TERMO sheets:

  • Preparing the base of the floor surface (clean the base from any dirt) the floor base must be smooth and even
  • Laying of an additional layer of thermal insulation (determined during the design process) TENAPORS EPS shall be used as an additional layer of thermal insulation
  • Arranging TENAPORS TERMO sheets: 
    • Insert a distortion tape along the entire perimeter of the room
    • Correctly arrange heating pipes (determined during the design process)
    • Cast fibro concrete on top of the arranged piping
    • The thickness of the concrete layer above the heating pipes shall be 35–40 mm
    • Arrange the main floor
    • The main floor may be laid only after the concrete has hardened completely (approximately after a month)



Water-heated floors may be installed only in buildings or flats with their own boiler. The sheets are used as a thermal insulation material for water-heated floors. The water-heated floors with TENAPORS TERMO sheets may be assembled on the ground, concrete decks, and also on concrete base floors. If necessary, TENAPORS EPS should be used as an additional thermal insulation material
