Roof Battens

  • Price

Category Information

Roof Battens, also known as roof tile battens and timber battens, are made of rough sawn treated timber and are typically used in roofing applications to add a gap between the roof tiles and the roof deck.

Roof batten sizes are typically 25mm x 50mm and 25mm x 38mm.

Technical Specification

Imported none graded timber roof battens are usually referred to as Type A. These are not suitable or allowed on NHBC new build sites.

Most Howarth Timber & Building Supplies branches carry TB33 roofing battens which are a high quality, graded batten, specifically produced to meet the requirements of the Building and Construction Industry. Available in both 25 x 38 and 25 x 50 sections and in lengths ranging from 3 to 6 metres.

Individual pieces are marked for full identification, highlighting size species, grade (TB33) and treatment process. High pressure preservative treated to BS:8417:2003 (UC2) which carries 60 year service life against insect attack and wood rotting fungi.

Visually graded at source the TB33 meets all aspects of BS5534:2003+A1:2010 with the exception of a final grade for knots, which must be carried out on site. This exercise is something that we would expect all roofers to do with all battens anyway given the nature of use.

All battens are manufactured from European Redwood (PNSY) or European Whitewood (WPCA).

The TB5534 is a premium batten available in 25mm x 38mm and 25mm x 50mm. This batten, as TB33, is fully graded to meet all aspects of BS5534:2003+A1:2010 but also includes a final grade for knots. Thereby eliminating the need for grading on site (which is now a requirement for all NHBC homes).

The TB5534 batten is independently accredited by BM Trada.
