Linear gap sealing
In a fire, four hours is a long time. And that’s how long linear gap sealing can buy you. Time to get out and get the professionals in.
If you’ve got gaps between door frames and compartment walls or between compartment walls and the ceiling (or any other gaps), you need linear gap sealing.
The size of the cavity dictates our approach:
Intumescent sealing is good for gaps up to 30mm. That’s a small opening, but fire and smoke get everywhere. If you’ve got imperfect fits and small void gaps in your head of wall and ceilings, fire and smoke will spread fast.
We’ll use acoustic intumescent sealant to seal those joints and void gaps. To ensure you’re properly protected for up to four vital hours.
- Tested to BS EN 1366-3 and BS EN 1366-4 for peace of mind
- Stops smoke in its tracks, saves lives
- Fast to apply and cure
- Works on many substrates and services
- Available in several colours.
- Head of wall
- Compartment walls
- Vertical and horizontal joins between different fire compartments
- Around fire-rated door frame and wall
- Between lift door frame and shaft wall.
Ablative coated batt and intumescent sealing
Large service openings can leave your building vulnerable to the spread of fire and smoke. With an ablative coated batt, you’ll get an air-seal barrier. It’s a mineral wool-insulation product with a high-performance ablative coating.
We can install it across walls, floors and seals, plus large-framed gap voids. You’ll get a critical four-hour window of fire-stopping. As a bonus, you’ll enjoy improved acoustics and less air leakage, so your building maintains its heat.
- Fast to install – little disruption
- Reliable and long-lasting – no further disruption
- Tested for airtightness – dependable
- Made from renewable resources – environmental.
- Typical applications
- Intumescent ceilings
- Larger gaps at head of fire-rated walls
- Fire-stopped ceilings

Movement joint soft seals
If movement is built into your building design, we can install movement joint soft seals. These create linear joint and penetration seals. Made from low-density stone wool, they’ll reinstate fire resistance, acoustic and air-seal performances in floors, walls and dry-wall systems that have large gaps.
The seal is a special foam laminated with intumescent layered on both sides. It’s designed for rigid walls and ceilings. Its beauty lies in its flexibility: it expands when exposed to heat.
- Tested to EN 1366-4 + A1: 2010 E 120, EI 120 and BS476 for peace of mind
- Stops fire for up to two hours
- Good acoustic isolation
