B1 FOAM meets the fire resistance class B1, which is the best fire resistance classification that can be obtained for a PU-foam. B1 FOAM has a high insulating value, thermic as well as acoustic, and meets all noise standards to 57 db. B1 FOAM has an excellent adhesive power to most materials. B1 FOAM has a high form stability; no shrinkage or post-expansion.

  • Accurate dosing.
  • No after-expansion.
  • Controlled expansion.
  • High form stability, shrink-proof.
  • Applicable at temperatures to -10°C.
  • Excellent mounting characteristics.
  • Perfect adhesion to most materials.
  • Corresponds to building classification B1.
