Steico Universal sheathing and sarking boards are specially designed not only to give superior insulation but to also enhance airtightness and reduce thermal bridging in pitched roofs and external walls. These damp-open wood fibre insulation boards protect your building from the negative effects of moisture whilst giving it extra stability.
Steico Universal sheathing boards are ideal for new build roof construction and insulation purposes. They can be left exposed for up to four weeks during the construction phase. Sheathing boards are approved for use by Building regulations and are certified by the FSC® chain of custody.
Steico wood fibre insulation is made from sustainably sourced wood fibres and thinnings. When used on a roof with pitches ≥ 18°, it also works as a water-resistant insulation board mainly due to its T&G profiling, which acts as a barrier not just to water but to air as well. This helps make you're building more energy efficient in general.
