In This Series
With timber facades being seen as a more sustainable option than their traditional brick counterparts, more and more housebuilders are opting to choose external timber cladding for their home. As a result of the growing popularity of timber cladding, it is important that builders have the necessary knowledge of the properties of some of the more common species used for cladding.
This Choose and Use sheet details all of the key considerations faced when specifying timber species for external cladding including each timber species' properties, ease of installation, weather resistance and overall robustness.
The sheet also covers the development of heat treated and modified woods such as ThermowoodÂ® PlatoÂ® wood, AccoyaÂ® and KebonyÂ® which have introduced an entirely new range of softwood products that can achieve greater durability without the use of preservatives.

Upgrading the fire resistance of existing doors is a...
Fire-resisting doorsets, as distinct from single 'fire door' leaves, are precisely designed and engineered component sets required to perform three main functions:
- To protect escape routes from the effects of fire (including smoke) so occupants can leave safely (includes lofts and conversions)
- To protect the contents and/or structure...
BM TRADA Product Assessor Simon Bailey highlights the importance of understanding fire and smoke control within buildings.
