LDBU Door Bottom & Intumescent Fire Seal
This retro-fit seal is used to upgrade fire door assemblies that have a door bottom clearance that exceeds the 10mm specified in AS1905.1.
LDPU Intumescent Fire Seal
This slim high performance intumescent fire seal is used to upgrade fire door assemblies that have perimeter clearances exceeding the 3mm specified in AS1905.1. When exposed to elevated temperatures the intumescent core rapidly expands in volume to restrict the passage of fire, hot smoke and toxic gas.
Key benefits
- Suitable for upgrading perimeter clearances up to 7mm.
- Cost savings for building owners as non-compliant fire door assemblies may be salvaged rather than replaced.
- Simple peel-and-stick installation, our aggressive self adhesive backing is tested on many surfaces to ensure seal longevity.
- Ideal for use in fire engineering solutions to limit the spread of hot gases around the edges of doors.
- Seal surface contains anti-microbial additives to restrict bacterial growth
