Timber has three main enemies – wood-boring insects, termites and fungi. However, these three invasive threats can be prevented by protecting the timber with an organic preservation treatment. At International Timber we offer a number of treatments to prevent an infestation and protect the timber. These include the organic preservation system Osmose Protim. This protects the timber against rot and decay and is used in construction projects that are required to Class UC1, UC2 and UC3 for roof timbers, timber framing, internal and external joinery and other timber projects that are above ground level.
