What Are Roof Battens Treated With?

Roof battens are typically treated with preservatives to shield them from environmental threats such as moisture, fungal decay, and insect infestation. These treatments significantly enhance their durability and lifespan, particularly under harsh weather conditions. A commonly used preservative is Tanalith E (Copper Azole), a water-based wood preservative that includes copper and an organic co-biocide. This treatment protects the battens from rot, decay, and wood-boring insects, ensuring they maintain their structural integrity over time.

How Long Do Roof Battens Last?

The lifespan of roof battens can vary widely based on several factors including the material used, the quality of the treatment, environmental conditions, and the quality of installation. Generally, treated timber battens, which are most commonly used, can last anywhere from 15 to 25 years. However, if the battens are exceptionally well-maintained and the conditions are favourable, they could potentially last even longer (up to 60 years!).

What Are Common Timber Roofing Batten Sizes For Cladding?

Although timber battens are known predominantly as a roofing product, they can also be used for cladding. Cladding batten sizes are very similar to the roof batten range, with dimensions of 19mm x 38mm, 25mm x 38mm and 25mm x 50mm. These then come in lengths of 3.6m and 4.2m respectively.The timber battens should be at least one and a half times the thickness of the cladding to ensure that they are thick enough to take the fixings where overlapping cladding panels are used. Again, this is a way to ensure the strength and durability of the finished project as well as ensure that the work done can keep out the elements.
