On average, roofing battens account for only 3% of the total cost of building a roof, but if a batten fails the consequences can be both serious and costly. Inspectors demand that the entire roof be stripped if battens are found wanting, or worse, it could result in a fall. With JB-RED pre-graded battens from John Brash, this is not a worry.
John Brash, responsible for the idea of pre-graded battens, has teamed up with Bracknell Roofing for a number of large projects for clients including Redrow, Bellway and George Wimpey.
Bracknell Roofing started using pre-graded battens in March, and is reportedly so delighted with the performance that it is now only using JB-RED for its batten requirements.
Alan Chumley, MD of Bracknell Roofing, said 'Our roofers can work with the added confidence that each of the individually strength-tested battens will provide the safest possible working access environment possible. Installation is easier too because the battens are lighter in weight due to the special preservative treatments used.'
Roofing batterns are believed to be the only timber product where grading is not consistently applied. But if they fail the consequences can be costly and dangerous.
Pre-grading batterns at the sawmill, rather than inexact grading on-site, has not previously been possible but pioneering work and over ?2 million of investment at John Brash has seen the development of such a process and the product is called JBRED. The procedure involves optical and laser scanning to ensure every battern is analysed.
A house, garage, and summer house in the New Forest have been roofed with Western Red Cedar shingles from John Brash.
The 400mm shingles were supplied in random sizes and laid with staggered or uneven butts, in order to provide a 'natural' aesthetic.
Tiles needed to be fire retardant, and the company's FRT Exterior full-cell non-toxic pressure treatment offered resistance to fire to British Standards. All shingles are treated in a vacuum pressure impregnation process with a preservative treatment.
With the use of western red cedar fire resistant shingles from John Brash, a new roof has been installed at St Mary's CE Primary School in Kent.
Curved in design, the roof required 1150m of shingles, which were used to create an aesthetic contrast to the peg tiles. The fire rating satisfied the local authority building control department, as there are domestic properties nearby.
High quality shingles from John Brash & Co. have been used to roof Jaguar House at Chester Zoo. Some 2,500m2 of cedar shingles have been installed to provide the ?finishing touches? to an extension to the building, and meet with the zoo?s sustainable resources policy to make use of natural materials wherever possible.
