Expanding Foam Insulation

Expanding polyurethane foam expands to fill gaps and voids, setting to become substantially rigid polyurethane foam which strongly adheres to the surfaces in which it is in contact.


  • Large areas can be insulated quickly
  • Areas can be insulated/filled where access is otherwise difficult
  • Prevents cold bridging (gaps between other forms of insulation can cause air leakage)
  • A high level of insulation performance can be attained
  • Prevents condensation
  • Adds to the structural stability
  • Excellent levels of airtightness
  • Sound prevention (some expanding foams have better sound attenuation properties than others)


  • Cavity wall insulation
  • Bonds inner and outer building substrate leaves together, i.e. for instances where wall ties are failing
  • Voids
