Best Attic Insulation for your Home


Thank you for visiting the official website of Weathershield Insulation. While we’ve only decided to go digital very recently, this product has been a success since 1976. Until now, word of mouth has been our main source of sales, but we strive to inform a much wider audience of our product’s benefits through this site.

What is Weathershield?

Weathershield is an eco friendly insulation product made from cellulose fibre, a processed paper material treated with harmless, naturally-occurring chemicals. The paper used in Weathershield is 100% recycled material. It is installed in the attics of commercial and residential buildings, and its superior performance has kept it a contender for almost four decades.


While Weathershield is simple to install yourself, we offer professional insulation installer services and are glad to answer any questions you may have.

Green Insulation

As well as being made from 100% recycled material, installing Weathershield will reduce both your heating bill and your carbon footprint, saving you money.


Our insulation is priced competitively, and the savings on your utilities on top of our helpful and informative staff ensure that you get the most out of every dollar.

What Our Customers Are Saying

Don’t just take it from us, let our customers do the talking!

“Our contractor used Weathershield cellulose fibre in our new energy efficient home. It works beautifully at keeping in the warmth and keeping out the noise of the city. As a bonus, it is made in Canada from recycled material. We have nothing but praise for this product.”

Jeanette Boman & Kevin Taft


“In the spring of 2005 we decided to replace the shingles on our roof. We had heard about cellulose insulation from a family member and decided while the roof would be exposed, we would re-insulate. We have an open beam ceiling in the front half of the house, and decided to insulate the walls in this area as well. In summer the house remains cool, and in winter it remains cosy and warm; we are very happy with the results.

We recommend using Weathershield Insulation products, it has saved us many dollars in utility costs.”

Zane & Jeanette Dorosh


“We have typically used Wallbar for noise reduction in interior walls.  Wallbar has given us an easy, economical way to provide sound damping for our customers in bedrooms, bathrooms, and sound room areas.

We choose Wallbar because it is an environmentally responsive alternative that doesn’t affect the environment or the occupants of the house.  It is efficient to install and doesn’t interrupt the flow of trade work in the house. The strongest feature of the product is the fact that it comes from a natural based, recycled product.”

“In addition to the insulation qualities of densely-packed cellulose insulation, I selected cellulose over foam due to the environmentally friendly manufacturing process and the fact that I could leave my lovely cedar siding in place, rather than covering it with foam-board and vinyl. I am pleasantly surprised by the quiet of my house since the insulation was installed – an unexpected benefit.”

“We use only Weathersield Cellulose insulation in our attics for a couple of very practical reasons.  The first is that the density of the product stops the movement of moisture which stops the problem of frosting on the underside of the roof in the attic.  The second reason is that we also receive less call backs that deal with problem attics due to poor insulation.”

“We use Wallbar in all our sound walls for our duplex and multifamily homes because we find that the density offered from cellulose stops the reverberation and echo.  It also dampens a full range of sound from low to high octaves.  We have tested Wallbar and have found it to be a far superior sound suppression system over all the other products available to us.”
