Description

STICK2 B1 fire rated expanding gun foam is a B1-classified gun-grade polyurethane foam (DIN 4102-1) with EI240 fire resistance per EN 13501-2, for sealing joints, cavities and service penetrations where a fire-rated foam is specified.

Perfect for:

  • Sealing linear gaps between monolithic, mineral or metal construction materials (max 30 mm wide, max 80 mm deep for the B1 classification)
  • Service penetrations through fire-rated walls and floors
  • Filling around door and window frames where fire rating is required
  • Acoustic and thermal upgrade of existing fire-rated details

Substrate Compatibility:

  • Bonds to brick, concrete, plaster, wood, metals, styrofoam, hard PVC and rigid PUR
  • Does NOT bond polyethylene, polypropylene, polyamide, silicone or Teflon

Key Features & Benefits

  • B1 fire classification to DIN 4102-1, plus Bs1d0 to EN 13501-1+A1:2010
  • EI240 fire resistance to EN 13501-2+A1:2008 (test method EN 1366-4:2008) for linear joints
  • Gun-grade can, fits a standard PU foam applicator gun
  • Free-foam yield 35 to 42 litres per can; 20 to 26 litres in a tested 35 x 1000 x 35 mm gap
  • Heat conductivity 0.036 W/mK, dimensional stability under 5%
  • Skin formation in 10 minutes, full cure in 24 hours
  • Cured colour pink for visual confirmation of fire-rated installs
  • CFC-free and HCFC-free formulation

Usage / Application

First, check the substrate is firm, clean and dry. Because the foam cures on ambient moisture, lightly mist the working surface with water before application.

Next, keep the can at +10 °C to +30 °C, with the optimum around +20 °C. For chilled cans, warm gently in water no warmer than +30 °C, never above +50 °C, because the can may burst.

Then shake the can vigorously for 10 to 20 seconds, valve facing down. After that, fit the can to a clean PU foam applicator gun and work valve-down for controlled output. Fill vertical gaps from bottom to top, and never overfill, because the foam expands as it cures.

For doors and windows, keep a minimum 10 mm and maximum 30 mm gap between the framing and the frame. Door and window fitting without mechanical coupling is not permitted, because the foam alone can distort the frame during cure.

Finally, cover cured foam with an opaque finish such as plaster, paint or sealant, because the cured foam is UV-sensitive. Clean uncured foam from tools with foam gun cleaner; cured foam needs mechanical removal.

FAQs

What does the B1 rating cover, and is EI240 the same thing?

B1 is a flammability class from DIN 4102-1 for materials of limited combustibility. EI240 is a fire resistance rating from EN 13501-2 (tested per EN 1366-4), describing how long a tested joint maintains integrity and insulation under fire conditions. Both apply to this foam in the tested geometries. Always check the test report matches your specific construction before specifying.

How much cured foam will one can produce?

Free-foaming yield is 35 to 42 litres per can. In a defined 35 x 1000 x 35 mm gap, the yield is 20 to 26 litres. Plan around the gap yield for fire-stopping work, because the foam expands less when constrained in a joint than when free-foaming on a test panel.

Do I need a foam gun for this product?

Yes, this is a gun-grade can with a threaded valve that fits a standard PU foam applicator gun. Clean the gun with foam gun cleaner after every session, especially if it will sit unused for more than 5 minutes, because uncured foam in the gun cures hard and ruins the tool.

Can I use B1 foam for any fire-stopping detail?

Not always. Fire stopping under UK Building Regulations and Approved Document B requires the detail to match a tested system. The B1 and EI240 classifications cover specific tested geometries (typically 10 to 20 mm wide gaps in aerated concrete construction). Always cross-check the TDS and your fire engineer's spec before substituting.

Does the foam need moisture to cure?

Yes, the foam cures on ambient moisture. For best results, mist the substrate lightly with water before application. In hot, dry conditions, the cure can stall without enough humidity, which is why a light mist makes a real difference.
