  • Upgrading my loft insulation was something id never thought about, after speaking to EFI I learnt that by just changing my current insulation to ICYNENE I can save so much more on my bills than I could by keeping Fibreglass. Very Informative
  • Extremely impressed with EFI who fully explained the difference between the Icynene spray foam and our current fibreglass. The team spent half a day in our house and even helped us clear out the loft. Even before they started spraying Brian showed me all the gaps i had in the loft.

  • A big thank you to the team at EFI for inflating our home with the Icynene spray foam. The team were on time, very polite and cleaned up after themselves. Completely shocked how quickly the house has warmed up, we are noticing the difference immediately.

  • Wish I knew about Icynene years ago, noticed a saving on my first gas bill. Thanks guys for being so efficient. Happy to recommend you to my friends.
  • After researching the different products available in Loft Insulation we decided to request a survey from EFI for Icynene. The surveyor immediately explained that Icynene is one of the most expensive products on the market but explained why. The explanation confirmed what we found online. When we agreed to insulate our home with EFI we had to keep to a pretty tight deadline. The installers arrived 2 days later, were extremely polite and tidy and insulated the whole roof without a fuss. There were finished in 4 hours. Extremely glad with our decision to install Icynene with EFI.
