Soudafoam FR HY

Soudal Soudafoam FR HY

Soudafoam FR HY is a single-component, self-expanding, ready-to-use polyurethane foam which has a fire rating of up to 240 minutes in certain configurations according to EN 1366-4. It uses CFC-free propellants that are completely harmless to the ozone layer. Every can comes with a straw adapter for quick, simple, and convenient application to fill gaps, cavities, and joints. With its high-yield formulation and an expansion value of 30 to 40x, each 750 ml can of Soudafoam FR HY can be expected to create up to 34 litres of cured, fire-resistant foam.

  • Manufactured with Soudal’s proprietary open-cell PU foam technology
  • Fire-rated up to 4 hours
  • Prevents the passage of smoke and gas through a joint
  • Excellent adhesion on most substrates (except PTFE, PP, and PE)
  • High thermal and acoustical insulation
  • Very good filling capacities
  • Comes with straw adapter; no other accessories required

750 ml pressurised aerosol cans, 12 cans / carton

  • Any filling, bonding, or mounting application requiring fire-retardant characteristics or a fire-rated product, such as:
    • Sealing of all openings in roof constructions
    • Sealing of cable and pipe penetrations
    • Creation of a sound-proof screen
    • Bonding of insulation materials

Health and Safety Recommendation

  • Apply the usual industrial hygiene.
  • Wear gloves and safety goggles.
  • Only use in a well-ventilated place, away from sources of fire and ignition.
  • Removed cured foam only by mechanical means. Do not burn away.
  • Consult label and safety data sheet for more information.


  • Shake the can for at least 20 seconds before use
  • Moistening the substrate surface and foam surface will promote adhesion and fine cell structure
  • Can must be upside down to extrude foam
  • Fill holes and cavities only 50%, as foam will expand
  • Cured foam must be protected from UV radiation – we recommend applying a sealant such as PERESEAL FR
  • Always store can with the valve pointed upwards
  • Generally, this product is one-time use; storage for follow-up use is possible but not guaranteed
