Fire Door Intumescent Protection
Intumescent Fire Protection Products and Kits
Choose the right fire door intumescent protection to meet project specifications, maintain compliance, and support the fire rating of your doors.
Fire door assemblies rely on tested and compatible components. When ironmongery is installed without the correct intumescent materials, it compromises the overall performance of the door.
Many types of door ironmongery require protection suited to their function and the door's fire resistance rating. Whether you’re upgrading an existing door or installing on a new build site, selecting the right intumescent ironmongery protection is essential.
Protect Ironmongery, Maintain Fire Door Performance
Even the most robust fire-rated ironmongery can’t perform as tested without appropriate intumescent material. An example is an FD60 lockcase that won’t maintain its certification unless installed with the matching intumescent lock protection kit.
Our range includes:
- Concealed fire door closer intumescent packs
- Intumescent pads for hinges
- Intumescent kits for flush bolts, door viewers, mortice locks, and digital locks
- Fire rated letterboxes with intumescent sleeves
- Intumescent air transfer grilles and vents
- Sheet material for cutting bespoke pattern intumescent protection
- Pipe collars for trunking and plastic piping
These components are designed to activate when exposed to heat. Material-dependent, they can expand up to 40 times their original thickness to fill air gaps and prevent the spread of fire and smoke.
Effective Passive Fire Protection Solutions
The intumescent products available in this category play a key role in passive fire protection. Once installed, they work silently in the background until needed. When exposed to high heat, they respond immediately in the event of a fire emergency.
They:
- Expand rapidly when exposed to heat
- Compartmentalise buildings to control fire spread
- Help protect escape routes
- Reduce damage to property
- Support compliance with Approved Document B
Options include both water based intumescent and solvent based intumescent products, depending on application. Check test evidence and select MAP, graphite, or sodium silicate products as appropriate.
Fire-Rated Vents, Letterboxes and Grilles
When maintaining air circulation or postal access through fire doors, it's vital to use products with integrated intumescent protection.
Our intumescent vents and intumescent letterboxes expand when temperatures rise, closing off potential fire paths. They are suitable for 30- and 60-minute doors and available in a range of finishes and styles to suit public buildings, schools, and residential premises.
Key features include:
- Tested and rated to match door fire resistance
- Compatible with both 44mm and 54mm thick fire rated doors
- TS008 and PAS 24 rated letterboxes for increased door security
Passive Fire Support for FD30 and FD60 Doors
The level of protection required will depend on the door's specification and certification. If fitting hardware to a 30 minute or 60 minute fire door, check the test evidence to confirm compatibility. Door seals may also be required if not supplied with the doorset. These could be intumescent strips or drop down door seals.
Where a cold smoke seal is also required, look for products combining intumescent and brush or blade seals in a single unit. If you're unsure which type of intumescent is needed for a given application, please contact our GAI-trained team for advice.
