Insulation is one of the best investments that you can make. We carry various types in stock.

Johns Manville


Fiber glass insulation can help lower your energy bills because it offers superior energy efficiency for the life of your home. Johns Manville's Formaldehyde-free™ fiber glass insulation also promotes better indoor air quality and a healthier environment because it's made without formaldehyde. What's more, since fiberglass insulation is made from glass, it's naturally mold- and fire-resistant.


This insulation also has the Easy-Fit technology. The edges are perforated in order to pull strips off for easy installation where the sutds are not a full 16"OC or 24" OC.We carry the popular sizes in stock. Ask one of our sales representatives to work out the quantity that you require.

White Styrofoam


PlastiSpan and DuroFoam are closed-cell EPS insulations. Both PlastiSpan and DuroFoam are moulded expanded polystyrene (EPS) insulations from Plasti-Fab. Their rigid closed-cell structure ensures long-lasting thermal insulation properties. DuroFoam comes in 4' x 8' sheets. Both are suitable and recommended as the insulation components in floor, wall and roof systems above and below grade. They are both easy to cut and install. DuroFoam offers the added advantage of a thin film laminated to the top and bottom surfaces that increases its durability in handling and installation. Its reflective face reduces radiant heat loss. Energy savings and conserving our natural resources from Plasti-Fab – another way to spell green. With energy costs skyrocketing, it just makes sense to improve the energy efficiency of your home or commercial building. You’ll save money on your heating and cooling costs as PlastiSpan and DuroFoam help you reduce your energy use by providing a constant R-Value for the life of your home. But more than that, Plasti-Fab products are a practical way to do your part in reducing the use of non-renewable resources. Not only do they reduce the use of these resources, but they actually consume less in their manufacture. Plasti-Fab has always placed environmental protection at the highest level of importance in our products, our processes and our practices. Our products are produced under rigorous technical standards, and have never contained chemicals associated with the depletion of the ozone layer of our atmosphere. That’s why we say Plasti-Fab is “another way to spell green.”

Energy Shield


Energy Shield® Exterior Wall Insulation Energy Shield® is the most cost effective, energy efficient sheathing material available in the marketplace. R-values range from 3.0 to 21.7, depending on thickness. We carry the 3/4", 1", 1.5" and 2" thicknesses. It has a slightly higher R value per inch than Styrofoam SM. Energy Shield® offers several “green” qualities, including zero Ozone Delpetion Potential (ODP) and zero Global Warming Potential (GWP) due to Atlas Blowing Agent Technology. When properly installed, Energy Shield® wall insulation will provide added insulation and yield immediate energy savings in both Commercial and Residential applications. Energy Shield® is manufactured with trilaminate facers (foil-kraft-foil) on the top side and a trilaminate or solid foil facer on the unprinted back side.Atlas polyiso has been tested for VOC and formaldehyde emissions, in which reported emissions were below the maximum emission levels allowed under both the GREENGUARD and GREENGUARD Schools and Children criteria. These tests confirm that Atlas polyiso insulation materials are all very low-emitting products.

Save Money

Insulation saves on heating and cooling costs. Ask our sales person to calculate your requirements.

Delivery Available

As with our other products, we can deliver. Insulation producrts are bulky.


Do not allow insulation to get wet. Therefore, make sure that you have a place to store it until you are ready.

Stud Centres

Homes and cottages have the wood studs spaced either 16" or 24" on centre. Order your insulation based on these sizes.


It is always a good idea to wear a mask when installing insulation.
