Recently the industry has demanded for 4 hour cavity fire socks to be installed in buildings. Previously 1 hour fire socks were standard practice.
We always listen to and work towards customer requirements and now we only stock Arc standard socks which are 4 hour fire rated in masonry up to 150mm.
Why use 4 hour cavity fire socks as standard?
Helps prevent loss of life
Allows emergency services more time to attend the fire
Delays the spread of fire to other compartments and neighbouring buildings
