John Brash is the UK's leading supplier of quality graded timber battens to the
construction industry. It has always advocated the need for quality battens and
was the first company to introduce a marking system clearly identifying supplier,
species, size, treatment and grade.
To help the roofing trade comply the NFRC have also published a handy technical
bulletin TB33 illustrating how the roof can comply with the new Standard.
John Brash was also the first company in Europe to offer fully graded battens
