Graded Roofing Batten to BS 5534:2003 (with the exception of final grading for knots and wane, which should be carried out on site)

• SR Timber Tanalised PREMIUM roof battens are a higher grade of the traditional roof batten that has been imported into the UK roofing and building sector for many years
• SR Timber Tanalised PREMIUM roof battens are produced in our own sawmill in Latvia, then imported as a finished product to our timber terminal on the Humber
• Compliant to all relevant standards - BS 8417:2003 (Preservation of Timber) and BS 5534:Part 1:2003 (Code of Practice for Slating and Tiling), except for final on site grading for knots and wane
• Manufactured full to size in both thickness and depth
• Available in both 25mm x 38mm and 25mm x 50mm profiles and lengths from 3.0m up to 5.4m, in 300mm increments
• Produced from the highest grade, slow grown spruce (Whitewood) Picea abies - WPCA or pine (Redwood) Pinus sylvestris - PNSY, all supplied from either FSC or PEFC fully certified resources
• Raw material is pre-graded prior to processing to enable an even higher finished grade of roofing batten
• Visually piece graded by our own qualified staff to BS 5534:Part 1:2003. However, we do recommend that SR Timber Tanalised PREMIUM roof battens are given a final grading on-site for knots and wane. This grading process is third party assessed and audited twice a year to ensure continued compliance to BS 5534
• By visual grading we are controlling the following defects :-
  Dimension
  Quantity of Knots *
  Wane *
  Fissures & Splits
  Slope of Grain
  Rate of Growth
  Decay and Insect Attack
  Size of Resin Pockets
• Battens are dried in order to comply with the correct moisture content as recommended by British Standards and should not exceed 22% moisture content at time of fixing
• Individually piece marked for full identity
• High pressure Tanalith E preservative treated to BS:8417:2003 with our standard 60 year lifetime warranty against insect attack and wood rotting fungi (when used correctly and installed above dpc level in buildings)
• Preservative treatment produces a distinctive pale green colouration that does not hide any potential defects within the batten

* These defects must be finally assessed on site prior to using any Tanalised PREMIUM battens.
