Introducing STEICO Wood Fibre Insulation from Kingspan

10 April 2026

Examples of STEICO flex 036 and STEICO universal dry

Kingspan Insulation is now offering STEICO flex 036 and STEICO universal dry as part of its full spectrum of insulation products.

The wood fibre boards are manufactured using softwoods sourced from PEFC certified forests and form part of Kingspan’s BioKor range of insulation solutions which are made of a minimum 80% bio-genic content.

They provide a combined sheathing and between stud/rafter insulation solution for walls and pitched roofs on new and existing buildings.

STEICO Wood Fibre Insulation

STEICO flex 036 achieves a thermal conductivity of 0.036 W/mK and as its name suggests, lends itself to simple, friction fit installation between rafters or studs in roofs, external walls and internal partitions.

STEICO universal dry is a wood fibre insulation sarking and sheathing board. It can be fitted as an above-rafter sarking board on roofs with pitches of ≥ 14 degrees, with STEICO flex 036 fully filling the rafters below. Alternatively, it can be used as a sheathing board on the outer face of timber frame wall studwork, with STEICO flex 036 friction fitted between the studs.

STEICO universal dry has a thermal conductivity of 0.043 W/mK. The boards feature tongue and groove edges which can help to streamline installation and support insulation continuity across wall or roof constructions.

Both STEICO flex 036 and STEICO universal dry are manufactured under a management system certified to DIN EN ISO 9001: 2015 (Quality management systems) and DIN EN ISO 14001: 2015 (Environmental management systems).

The products are available through specialist insulation distributors and selected builders’ merchants across Great Britain and are backed with support from Kingspan Insulation’s technical services team.
