When choosing spray foam or any other type of insulation, it is important to note that they are not all created equal!


Open cell spray foam is a lower density, nonstructural insulation with an R-Value of around R-3.75 per inch. It is not considered to provide a vapour barrier and should never be applied below grade.


2lb closed cell spray polyurethane foam boasts superior performance due to its high R-Value per inch and is a complete moisture/vapour/air barrier. It expands to adhere to irregular surfaces and gets into tiny cracks, crevices, and minor imperfections. This air-sealing property makes it ideal for basements, crawl spaces, overhangs, cathedral ceilings, rim joists – the list goes on! The seal provided by 2lb closed cell insulation prevents dust, mold, and other allergens from entering and can even improve a building’s structural strength by up to 400%.


Although closed-cell foam is by far the best insulation product on the market, if your home was built before 2012, chances are you could benefit from an attic top-up with blown-in fibre glass or cellulose. At only about R-2 to R-4 per inch, you need a properly installed, thick layer to achieve good thermal resistance. It does not provide a seal. However, this is a cost-effective way to reduce heat transfer. Liam and his crew can install loose-fill fibre glass or cellulose on top of on your existing insulation. This is a quick, easy and cost-effective way to start reducing your bills and improving the comfort of your home.

I had my crawl space done and it made a huge difference to the comfort in my home. last winter my floors were always cold, which in turn, have to turn up the heat to compensate. The floors are warmer now, so it should cut down on the light bill. These guys are very professional and do very tidy work. I highly recommend them for the job.

The process from start to finish was great, from the speedy and accurate quote to the level of tidiness when installing the foam to the clean up. Island insulation was a great company to deal with, and had all the information on insulation rebates offered by NL Power to make the decision on installing spray foam easier.

My 140 year old Victorian home, in downtown St. John's, was always cold in the winter. Pipes would freeze, and my floors would feel like ice every February. Not anymore! Ever since Liam worked on insulating my crawlspace the home has been much easier to keep warm. Even on the coldest day of the year the temps inside are toasty. The oil in my oil tank now lasts twice as long before fillup, and the floors are warm enough to walk barefoot! Best of all, the pipes no longer freeze. I'm stunned at the difference, and the price even came with an over 50% rebate from NL Power. Using Island Insulation was the best choice I made in 2019. Would definitely recommend their trustworthy service to anyone. 5 stars out of 5!
