240mm STEICOflex 036 is a flexible, high‑performance wood‑fibre insulation slab designed for exceptional thermal comfort, acoustic absorption and healthy building performance. Made from sustainably sourced wood and certified to rigorous European standards, it offers one of the best thermal conductivities available in natural fibre insulation, making it a premium choice for energy‑efficient construction. STEICOflex 036 is a soft, flexible insulation batt manufactured from natural wood fibres. Its dense yet elastic structure allows it to friction‑fit tightly between studs, rafters and joists, eliminating gaps and thermal bridges. The material is vapour‑open, helping buildings regulate moisture naturally and supporting a healthy indoor climate. It is suitable for both new builds and renovations, performing exceptionally well in pitched roofs, timber frame walls, ceilings and internal partitions.
