When to choose this

Thunder Bay Insulations provides industry leading attic solutions. Our projects range from new builds and retrofits to renovations. Blown-in insulation is the best insulation option for your attic whether residential or commercial. This family-safe alternative to traditional fibreglass can be applied to un-insulated area such as new builds or it can be used as an economic top-up for already existing insulated attics.


Ontario Building Code has set attic insulation at a value of R-50. Thunder Bay Insulations uses Knauf Jetstream Max insulation, which allows us to reach a R-50 value with only 18 inches. Jetstream Max is Greenshield certified child and school safe. We use the industry leading products with your family safety in mind.

Go Green

The insulation we use is made from 55% post consumer recycled material, will help to reduce the carbon footprint of your home or business and help save you money on your next heating bill. Keep your home or business cooler during the summer and warmer during the winter.

Consider blown-in insulation options if your attic:

  • Is a new build
  • Is a retrofit
  • Needs a top up
  • Is under renovations
