Our Service

Liam Wickens is the owner / operator of Island Insulation. Liam personally handles each estimate and consultation to ensure every residential and commercial customer has a full understanding of the products and the process.

Island Insulation only uses products supplied by top quality, trusted manufacturers that are 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 the preferred option for most of our customers. It provides optimal benefits with 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 and 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 insulation

Open cell spray foam is a lower density, nonstructural insulation that offers 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.

Closed cell spray foam insulation

Closed cell spray foam is a medium density, structural foam that provides a complete moisture/vapour/air barrier and boasts much higher performance than any other type of insulation at R-6 to R7 per inch.

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!

- Louis

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.
