Liam Wickens is the owner/operator of Island Insulation. Liam handles each estimate and consultation to ensure every residential and commercial customer fully understands the products and the process.

Island Insulation only uses products supplied by top-quality, trusted manufacturers registered and regulated by Canadian third-party quality control systems. This stringent system ensures both product and installer adhere to strict regulations, including specialized training, with quality, safety, and efficiency in mind. Our employees carry up-to-date industry certifications.

Due to its tried and trusted superior insulating properties, closed-cell foam is preferred by most customers. It provides optimal benefits with a high R-value and acts as an effective vapour barrier while adding structural strength. Its common applications are found in home energy efficiency improvements such as basements, crawl spaces, rim joist areas, as well as in commercial and industrial structures and new home builds.

We will work with you to determine the best type of insulation for your specific needs.

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.

There is a right tool for every job. Liam and his team are here to guide you through the process!

These guys were super easy to deal with and did a thorough job in a challenging space. I have an older downtown home with a weird crawl space which they handled in a expert manner. Highly recommend.

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!

- Andre

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.

Nice job done and very professional!

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.
