STEICOtherm
Stable wood fibre insulation board
STEICOtherm is a stable wood fibre board for flat applications on roofs and walls, and as a stable insulation layer in floor build-ups. On roofs it is typically used as over-rafter insulation together with a sarking board or roofing membrane.
It insulates well in winter and protects against summer heat, uses the wood's own lignin as a binder, and is vapour-open for a safe construction.
Key advantages
- Easy and fast fixing
- Excellent insulation properties in winter and summer
- Product made from wood fibres, independently certified by the FSC®
- High compression strength
- Water vapour open
- Enhanced vapour transfer. Helps to regulate the indoor climate
- Ecological and environmentally friendly
- Fire-resistant and economic construction
- External insulation for roofs or floors with discontinuously laid coverings or under sarking felt.
- Interior insulation for floors or roofs,
- Sound insulation in partition walls
- Insulation between rafters
- Insulation under a screed
- External insulation for walls
- Behind a rain screen
- Insulation for timber structures
