STEICOuniversal dry

Combined sarking, sheathing and render board

Insulating sarking, sheathing and render board - high stability even with low board thicknesses

4-fold function: cold protection, rain protection, wind protection, render board
Can be used from 35 mm board thickness in conjunction with STEICO air-injected insulation
Particularly economical – just one type of board for roof constructions (from 1880 mm in length) and rendered façades (from 40 mm in thickness)
Particularly robust insulation board thanks to the high raw density
Diffusion-open for increased structural safety
Wood from responsible forestry - PEFC certified

Bonded carbon

During growth, trees absorb carbon dioxide (CO₂) and split the molecule into carbon (C) and oxygen (O₂). The carbon is bound in the wood. The amount of bound carbon (C) is therefore also referred to as CO₂ equivalent (CO₂eq). As long as the wood is used in the form of wood products, the carbon remains bound and is removed from the atmosphere.

Biogenic carbon content in the product according to EN 15804+A2

approx. 353 kg CO₂-eq./m³

Notes

Storage

Store wood fibre boards horizontally, flat and dry
Protect edges from damage
Only remove the film packaging when the ambient climate is dry and keep the pallet packing label
Maximum stacking height: 4 pallets

Disposal

Waste cuttings:

Waste code according to 2014/955/EU: 03 01 05

Dismantling:

Waste code according to 2014/955/EU: 17 02 01

Cutting

The boards can be cut to size using the STEICOisoflex cut combi cutting table or a band saw, circular saw, jigsaw and other wood-cutting tools.

Occupational health and safety

STEICO wood fibre boards can be walked on directly above a rafter or joist support, however they cannot be used as the primary walking surface
To ensure that the roof can be walked on at all times, it is advisable to lay the battens at the same time.
Additional fall protection (man safe systems) should be used in line with national guidelines
Suitable protective measures must be taken when cutting the wood fibre insulation boards. (dust extraction, dust mask)
HSE guidance on the safe cutting of timber and the management of wood dust should be followed

Building moisture

Condensation on the side of the panel facing the room during the construction phase disrupts (hinders) the diffusion flow.
Excess moisture caused by e.g. fresh screed, plaster, or paint must be removed by ventilation
Dry air must be ensured inside the building during the construction phase.
