Tanalised Type A Roofing Battens 25mm x 50mm provide a consistent, reliable fixing surface for tiles and slates on pitched roofs. Pressure-treated to BS 8417 Type A standard using European Redwood or Whitewood, these battens resist rot, decay, and insect attack throughout the roof's service life.
Specifications
| Property | Detail |
|---|---|
| Material | European Redwood or European Whitewood |
| Treatment | Tanalised - pressure-treated to Type A standard (BS 8417) |
| Grade | Type A Roofing Batten |
| Nominal Size | 25mm x 50mm |
| Profile | Sawn |
| Length(s) | 4.5m, 4.8m, 5.1m |

What it's used for
- Fixing roof tiles and slates to rafters on new-build pitched roofs
- Re-roofing projects where existing battens need full replacement
- Repair and maintenance work on residential or commercial pitched roofs
- Counter-battening over breathable roofing membranes to create a drainage and ventilation gap
Fitting and handling
Store battens flat and off the ground under cover before installation to prevent warping, and allow them to acclimatise to site conditions where possible. Fix to rafters at spacings recommended by your tile or slate manufacturer, using corrosion-resistant nails or screws throughout - stainless steel or hot-dipped galvanised fixings are suitable choices for long-term performance. Treat any cut ends promptly with a compatible end-grain timber preservative to maintain the protection provided by the Tanalith treatment.
FAQ
What is the difference between Type A and Type B roofing battens?
Type A battens meet a higher grading standard than Type B, with stricter limits on knots, slope of grain, and wane. For most domestic pitched roofs, Type A battens are specified to ensure consistent strength and fixing across the rafter span.
Do I need to treat cut ends on Tanalised roofing battens?
Yes. The pressure-treatment process penetrates the timber but cutting exposes untreated wood at the end grain. Applying a compatible end-grain preservative to any sawn ends on site maintains the batten's resistance to rot and moisture ingress.
What fixings should I use with 25mm x 50mm roofing battens?
Use corrosion-resistant fixings throughout - stainless steel or hot-dipped galvanised nails are the standard choice. Bright steel or zinc-electroplated fixings are not recommended as they can corrode prematurely, particularly where the timber retains moisture or where the preservative treatment is present.
