Working with one of the world’s largest hardware manufacturers, Vanquish have successfully tested a 450mm flush bolt in 3 different configurations with a single strip of FlexiFire HE fully concealed within the mortice. The test was to BS EN 1634-1 and was on a full-size double leaf doorset.
We achieved a 20% overrun on the 30-minute test and a 10% overrun on the 60-minute test. We are always thinking of innovative ways to improve hardware protection without compromising on aesthetics!
