Pyroplex Fire Only Intumescent Door Seal 38mm x 4mm x 2100mm
The Pyroplex Fire Only Intumescent Door Seal provides a traditional intumescent fire seal for fire-resisting timber door assemblies.
Installed into a rebate in either the door leaf or frame, the intumescent material expands when exposed to fire to help seal the gap between the door and frame and restrict the passage of fire and hot gases.
The 38mm x 4mm profile has primary test evidence for 60-minute fire-resisting systems, subject to the configuration and supporting doorset evidence.
Pyroplex rigid box seals feature a durable outer casing and an acrylic self-adhesive backing, making installation straightforward without the need for specialist tools.

Fire seals are designed to provide passive fire protection by controlling & slowing down the spread of fire within commercial, industrial, public and residential buildings. This allows enough time for evacuation and emergency services to attend.
Fire seals are passive protection which work automatically without any power unlike sprinkler systems or alarms and enhances other fire systems more effectively.
Most fire seals are designed to last 10-20 years under normal conditions, however if they are damaged then they should replaced straight away. We recommend regular inspection of fire seals.
Fire seals should be inspected regularly and we recommend every six months and when there has been damage to the fire seals replace them immediately.
Damaged fire seals compromise the passive protection against fire and increases the risk of fire spreading throughout the building.
Intumescent strips are fire resistant passive protection products. When exposed to extreme heat they are activated and expand to control & prevent the spread of fire. Intumescent strips provide passive protection through gaps around doors, fire doors, windows and cable/pipe access.
When exposed to fire the intumescent material in the strips activate that causes them to expand to 10 times their original thickness. This expansion fills gaps, cracks and prevents flames and hot gases from passing through and spreading.
Intumescent strips are available in various fire ratings, typically ranging from 30 to 120 minutes depending on the intumescent strip product.
Intumescent strips have a lifespan of 10-15 years when properly maintained and without heavy use of preventing fire from spreading.
Yes, intumescent strips should be inspected annually for damage or deterioration and gaps.
