Cewood Wood Wool Board
Product Overview
Main purpose
A breathable thermal and acoustic insulation panel that can be directly plastered on to.
Use it on
Internal or external walls and ceilings. The 15mm board is suitable for internal use only with 600mm (or narrower) centres. When 25mm thick Cewood is used externally, a supporting board (e.g. OSB) is required directly behind. If no supporting board is used externally, a thicker Cewood board is required. With 400mm centres externally, a 35mm Cewood board must be used; with 600mm centres externally, a 50mm thick Cewood board must be used.
Overview
Cewood Wood Wool Construction boards are thermal and acoustic insulation boards made from 3.00mm wide wood wool strands bound together with cement. The wiry ‘bird’s nest’ structure has a huge surface area which provides an excellent key for direct plastering. As a breathable (vapour open) carrier board, it is ideal for plastering with lime-based plasters and provides an alternative to gypsum plasterboard for internal finishes on any type of wall. Cewood wood wool insulation boards are B-S1,d0 Euro fire class rated.
Features
- Provides thermal and acoustic insulation
- Moisture vapour diffusion open
- Can be used internally or externally
- Strong and stable carrier board for plaster or render
- Ideal for newbuild and refurbishments / retrofit
Benefits
- Fibrous "birds nest" structure provides an excellent key for lime plaster or render
- In historic buildings or new build construction allows moisture vapour to diffuse through the building envelope in both directions.
- Highly stable; will not shrink or compress over time so is ideal for older buildings with changing/variable humidity levels.
- Improves U-value and thermal mass of the building element, which reduces heat loss in winter and reduces overheating in summer
- The fibrous structure and density provides better acoustic noise reduction, improved acoustics and higher comfort levels for occupants.

Key Technical Data
Installation Guide
Cewood Wood Wool boards can be directly fixed to timber studs, rafters or battened walls using galvanised 45mm x 4.5mm wood screws or with galvanised nails with washer (diameter ≥ 20mm). Twelve fixings per board are required for the 2400 x 600mm boards and 6 fixings for the 1200mm x 600mm board.
The boards should be installed perpendicular to timber studs/rafters parallel to horizontal battens. The smaller boards should be staggered and installed in a brick style pattern on large areas.
Once fixed, Cewood Wood Wool boards can be directly plastered onto. No primer is required.
