    Product Description

    25mm x 50mm x 4.8 Meters - Stamped Blue BS5534 Roofing Batten

    • BS 5534:2003 states the requirements for roofing battens, and includes information about the species, grades, treatment and required markings.
    • Pressure treated with preservatives to enhance resistance to rot and insect attack
    • Most organisations, for example National House Builders Council & Local Authority Building Control require fully-compliant battens.
    • NHBC now require that timber used for battens should be indelibly marked to demonstrate compliance with BS 5534
    • Although not a legal requirement, BS 5534 sets out the standard for battens. The best way to ensure battens are fit for purpose is to choose those marked as BS 5534-compliant.

    Why are roof battens different Colours?

    Manufacturers often add a coloured dye to their preservative treatment process to differentiate non-graded batten from BS5534 Batten. The colour itself does not matter, and is decided by the manufacturer at the time of treatment. There is a wide variety of colours including Red, Blue & Gold available, but this is not enough to show the battens meet BS 5534. Every BS5534 graded batten must be indelibly marked / stamped with the following:

    • Timber Grading: BS 5534
    • Size
    • The manufacturers? / graders name
    • The timber species
    • A third-party certification scheme

    What fixings do I need for 25mm x 50mm x 4.8 Meters - Stamped Blue BS5534 Roofing Batten?

    British standards BS 5534 and BS 8000-6:1990 give the information you need for fixing and installation:

    • Ensure battens are fixed to rafters at centres not more than 600mm apart
    • Ensure battens span at least three trusses and are therefore more than 1.2m long
    • Batten moisture content (after treatment) should not exceed 22%
    • Use round shank nails, 10 gauge and usually 65mm long
    • Use zinc coated nails where extreme weather (e.g. coastal conditions) might be experienced
    • Use galvanised nails when fixing treated timber battens to avoid corrosion
    • Nail through the middle of the batten into the middle of each rafter
    • Cut joints square and butt joint at the centre of each rafter, providing maximum support and fixing
    • Replace any battens that have split due to nailing

    What size batten do I need?
