If you’re installing your Insulation Board between rafters, follow these steps;

  • Before cutting the Insulation Boards measure the space between the rafters as sizes and spacings will vary slightly
  • Using a sharp knife or fin-toothed saw cut the insulation boards to size
  • Fit the insulation flush with the bottom of the rafters. Make sure that it doesn’t fill the entire depth and ensure the Insulation Boards are installed tightly between the rafters
  • Fill any left-over gaps with expanding foam sealant
