Insulation Tile Backer Board



Termofol Board
Tile Backer Boards are made of XPS foam with glass-fibre reinforced cement coating.
The boards are resistant to water, moisture and humidity; non-capillary, lightweight and
easy to cut – ideal for underfloor heating, especially in wet-room areas. Suitable for
tiles, mosaic, natural stone, plasters and putties. They allow quick, easy and creative
construction with reduced drying time. The special XPS benefit: thermal insulation
performance is unaffected by wet or damp conditions.
Specification: Thickness 6 mm
- Area: 0.60 m²
- Thermal conductivity: λ = 0.033 W/(m·K)
- XPS foam density: 32 ± 0.02 kg/m³
- Fire resistance class: E (hardly flammable)
- Compressive strength: ≥ 300 kPa (10% def.)
- Water absorption (48h): < 0.2%
- Bending strength: 0.30 ± 0.02 MPa
- Water vapour permeability: 0.028 ng/Pa·m·s
- Vapour diffusion resistance: 110–225 μ
- Impact noise reduction: ΔLw = 21
- Working temp.: −50 °C to +70 °C
High pressure and crush resistance. Resistant to fungi and mould, non-rot. Fire resistance.
Easy to process. Effective ground insulation thanks to the XPS TERMOFOL board. Substrate
waterproofing and excellent thermal insulation while maintaining 6 mm thickness.
The core is extruded polystyrene (closed cells) for strong thermal performance; the outer
layer is a polymer mass with resin and embedded glass-fibre mesh for low weight and high
impact resistance.
TERMOFOL SUPERTERM Insulation Board
Specially designed to deliver top performance in underfloor heating systems.
The TERMOFOL SUPERTERM board is intended for thermal insulation between floating vinyl floor panels and the concrete substrate. It can be used in residential and commercial buildings.
It effectively prevents heat loss, levels the surface, and reduces unwanted noise in the room. It also acts as an excellent barrier against mold and mildew.

Key product features:
Size: 120 x 80 cm
Thickness: 6 mm
1 board = 0.96 m²
Designed for floating vinyl floors
Levels local unevenness of up to 0.88 mm — no need for floor repair
Allows for fast floor dismantling without damaging the subfloor
Enhances underfloor heating efficiency
Excellent acoustic comfort — high noise reduction
High compression resistance
Made of XPS (extruded polystyrene)
100% recyclable, freon-free, ozone-friendly
