Door Seal Buying Guide
What is an intumescent door seal?
An intumescent door seal is designed to expand when exposed to high temperatures, helping close the gap between the door and frame during a fire. Intumescent seals are commonly used as part of a fire-rated door assembly.
What is the difference between fire seals and smoke seals?
Fire door seals are designed to resist heat and flame, while combined fire and smoke seals also incorporate a brush, fin or similar element to help restrict the movement of cold smoke. The appropriate seal should be selected according to the specification of the fire door.
What size door seal do I need?
Door seals are available in different widths and depths to suit the groove or channel in the door or frame. Measure the existing seal and check the required groove dimensions before ordering a replacement.
Where are intumescent door seals fitted?
Intumescent seals are typically fitted into a prepared groove in the door edge or frame. The exact location and installation method depend on the door set and seal specification, so always follow the manufacturer's fitting instructions.
Do fire doors need smoke seals?
Where smoke control is required, a suitable fire and smoke seal may be specified alongside the intumescent component. Check the fire door's certification and installation requirements to determine which seal configuration is appropriate.
What are acoustic door seals?
Acoustic door seals help reduce sound transmission through gaps around a door. They can be used on internal doors where improved acoustic performance is required, subject to the requirements of the door and surrounding frame.
Can door seals help with draughts?
Suitable door seals can help close unwanted gaps around internal doors and reduce draughts. Choose a seal designed for the size and location of the gap, and check that it does not interfere with normal door operation.
Can I replace an existing fire door seal?
Yes, but replacement fire door seals should be compatible with the existing fire door specification. Check the seal dimensions, profile and required performance before replacing it, and follow the manufacturer's installation instructions.
Why is the correct door seal important?
The seal forms part of the overall door assembly, so using the correct specification is important for the door to perform as intended. For fire-rated doors, always use compatible components and follow the relevant manufacturer's requirements.
