Insulation Work in St. Marys, Perth County

St. Marys is known as Stonetown for its extensive use of the local cream-coloured limestone in its historic buildings and residences. The town has one of the most distinctive architectural characters in rural Ontario - limestone homes, churches, and commercial buildings from the mid-to-late 1800s line the streets of the older residential areas. These heritage limestone homes present the same insulation challenges as the stone homes in Guelph and Fergus - the building assembly and moisture management approach must account for the stone construction. The postwar residential streets are more standard and benefit from the full range of spray foam applications.

Victory Insulation is based in Cambridge and serves St. Marys and the surrounding Perth County area. Every job is handled by the owner. No call centres. No crews you have never met.

Closed Cell Spray Foam - Technical

Why Closed Cell Is the Right Choice for St. Marys

Ontario's climate demands a product that insulates, air seals, and manages moisture all at once. Closed cell spray foam does all three. We do not install open cell foam - it does not meet the performance requirements for most Ontario applications.

R-6 to R-7

Per Inch of Thickness

Among the highest R-values per inch of any common insulation. Two inches on a rim joist delivers approximately R-14. Three inches at the attic deck hits R-21 before any additional insulation is added. Critical in thin assemblies where batt insulation cannot perform.

2" or more

Vapour Barrier at 2 Inches

Closed cell spray foam at 2 inches meets Ontario Building Code vapour barrier requirements. No separate poly sheet required in most applications. Eliminates the moisture and air sealing failures that are standard with batt insulation in Ontario crawl spaces and rim joists.

Permanent

Does Not Degrade

Closed cell spray foam does not compress, settle, absorb moisture, or lose R-value over time. It bonds permanently to wood, concrete, and steel. Once installed correctly it maintains its performance for the life of the building with no maintenance required.

What makes Victory Insulation different from franchise spray foam companies? +
Victory Insulation is independently owned and operated. Dan has been in the trades since 2002 - starting in roofing and exterior siding before moving into spray foam.
