New WIS on metals helps specifiers avoid the perfect storm

Metals have a long history of working in harmony with timber in the built environment, especially in dry conditions, where a marriage between the two on fixings, flashings, connectors and such-like can often last a lifetime.


But for structures and buildings situated in a damp environment, such as coastal properties, swimming halls and boat builders, greater care needs to be taken to avoid the corrosive effects of sea water as well as wet, damp and adverse conditions.


Moisture is the nemesis of combining metals with timber – get the specification process wrong and it could lead to the release of acidic vapours, which not only degrade metal, but also fabrics and documents, putting libraries, museums, art galleries and conservationists also at risk.


Luckily, this problem can be easily rectified with the aid of TRADA’s new WIS Specifying metals for use with timber.


The new WIS guides you through the specifying metals maze, providing examples of where the risk of corrosion of metals by timber is most likely to occur and outlining the steps that should be taken to ensure moisture content is controlled.


Packed with useful advice on design, storage, construction and maintenance, the WIS is written with buildings and structures vulnerable to adverse weather conditions in mind, but can also be applied to all timbers as a precautionary measure - helping members to stay one step ahead by knowing what to look out for.
