Cavalok's burning ambition
September 2009
Cavalok Building Products is celebrating following excellent results in rigorous fire tests to BS EN 1363 standards on its cavity closers by Chiltern International Fire.
100mm to 150mm cavity closers achieved greater than 60 minute integrity in a timber frame construction and over 90 minutes in masonry.
The tests were commissioned by Cavalok in response to the need for improved fire assessment of cavity closers and further tests are now being carried out on Cavalok’s new cavity closer ranges to achieve even higher fire ratings enabling customers to satisfy Part B of the building regulations.
“This comprehensive testing will enhance specifier confidence in the Cavalok range even further,” said Robert Cridford, Technical and Design Manager at Cavalok. “The testing recreates the ‘flashover’ point in a building fire, subjecting our products to an intense 1000°C furnace until the product fails. We found that our product outlasted the timber frame construction it was mounted in, a great result which ensures there are no doubts about Cavalok closers.”
Preparations for the next series of tests are taking place, which include a number of products within Cavalok’s new ranges. These will be available once the testing process is completed. Until then Cavalok's FireSok range helps customers meet the needs of Part B.
