Seals

A Deanta Fire Seal is an intumescent strip designed to expand when exposed to high temperatures, sealing gaps around a fire door to prevent the spread of fire and smoke. Installed within the door frame or door leaf, it plays a critical role in maintaining the fire-resistance rating of certified fire doors, such as FD30 or FD60 doors.

Yes, Deanta Fire Seals are essential for FD30 and FD60 rated fire doors. Without properly fitted intumescent fire seals, a fire door may not perform as tested and could fail to meet UK building regulations. Always ensure the seal type and size match the door’s fire certification requirements.

Deanta Fire Seals contain intumescent material that reacts to heat. When temperatures rise, the material expands significantly, closing the gap between the door and frame. This expansion blocks flames, hot gases, and smoke from spreading, helping to protect escape routes and limit property damage.

Deanta Fire Seals are available in various widths and thicknesses to suit different fire door ratings and gap requirements. Options may include:

1. Intumescent-only fire seals
2. Combined intumescent and smoke seals
3. Self-adhesive or rebated installation types

To install a Deanta Fire Seal, the seal should be fitted into the designated groove (rebate) in the door or frame. It must run continuously along the top and sides of the door without gaps or breaks. Always follow manufacturer guidelines and building regulations to maintain fire door certification.
