Application
PU28 Fire Barrier is laid horizontally across the rafters with 75mm overlap on all joints. PU28 Fire Barrier can either be stapled or nailed to the rafters and then battens are fitted over the top with 300mm centres, with the first batten 125mm from the arris rail. PU28 Fire Membrane can also be used for other Fire Barrier applications such as fire curtains.
If required, TAS Fire Silicone can be applied between the membranes at the point that they join. For best results; apply a 5mm diameter bead of silicone using a wave effect pattern within the 75mm overlap point.
Although the TAS Fire Silicone will have some instant grip, it will require 24 hours to fully cure. For best results. please ensure that the surface is clean and dry and not exposed to frost during the curing process.
Systems
To achieve both integrity and insulation, PU28 Fire Barrier needs to be used in conjunction with Thatchbatts® to create a more comprehensive thatch fire barrier and increase thermal insulation values. Please see Thatch Fire Membrane System for more details.
