Roof batten sizes

Timber roof battens, when it comes to sizes, can vary. This is because many are locally sourced. So the length of roof battens, in particular, can typically be as short or as long as required.

If you order the total linear meterage required, the timber will be provided in lengths available. Additionally, you may be provided blue or red batten because of material shortages. These still comply with BS5534.

C16 timber sizes

C16 timber is commonly used in floors and roof joists in internal building work. It’s also typically chosen as the standard timber for roof extensions or joist refurbishment. This is because it is the most cost-effective internal structural timber.

Note that this particular timber is kiln-dried certified to comply with the criteria of strength grade C16. These requirements also request the timber to be machine graded, with the number of knots, the slope of the grain and fissures in the timber being considered.
