External Cladding Solutions

External Cladding Solutions

Timber cladding is becoming increasingly more popular as a facing material, replacing brick or rendered finishes. When using the cladding for external applications durability of the timber must be considered. Due to the wet and windy climate that we experience in the UK, building façades are best designed in the form of a rain screen. The design allows rainfall to be deflected but allows moisture that gets into or through the outer layer to dry out before it does any damage.

Species such as Western Red Cedar and European larch continue to be the most popular product for exterior cladding, but thanks to new modified methods other species such as Accoya and Thermowood are also widely used. These products achieve greater durability without the use of preservatives.

At International Timber you can be confident that species within our cladding range are suited to perform in external rain screen situations.


To prolong the appearance and enhance the beauty of your timber cladding, International Timber provides a choice of coating options. Recently developed by working with a leading chemist, International Timber is now offering their own high performance coating for external applications. We are also approved factory coaters for all leading paint manufacturers (Sikkens, Omnia and Teknos).
