STEICOinternal
Wood fibre insulation boards for internal insulation
STEICOinternal is a wood fibre board system for insulating external walls from the inside. It is capillary-active: it can absorb moisture and release it again, which helps keep solid and stone walls dry and healthy.
A good solution for older Irish homes where the façade can't be changed, and where synthetic internal insulation could trap moisture.
Key advantages
- Environmentally friendly internal insulation made from natural softwood
- Ideal for renovation of masonry and traditional timber constructions
- Excellent control of condensation – advanced performance using intelligent building physics
- Can be utilised without an additional vapour barrier
- Water vapour open for a healthy internal climate
- Ecological and recyclable with no impact on the environment.
