Intustrap has been designed to allow thermally insulated copper pipes to pass through fire walls and floors, without the need to cut away the thermal insulation to maintain the compartment FRL. This avoids the common practice of cutting away thermal lagging to fire stop directly to a chilled water pipe which can cause cold bridging and condensation, leading to damp walls and ceilings below and around the chilled water pipe which may also eventually damage the integrity of the fire wall or floor.
Intustrap is cut to length and wrapped twice around the thermally lagged pipe where it passes through the fire compartment. Then fire stopping is required around the perimeter of the Intustrap.
Intustrap has also been tested around small PVC and HDPE pipes and is installed in the same manner as above. It is ideal for use in plasterboard, masonry, Speedpanel walls and masonry floors. It is also fully fire tested around thermal insulation of PIR, NITRILE RUBBER, ROCKWOOL and GLASSWOOL.
- FRL-/120/120 for thermally lagged pipes
- FRL-/240/240 for small PVC pipes
