Insulation Work in Guelph, Wellington County

Guelph has one of the most distinctive housing stocks in Southern Ontario - the downtown core is full of limestone heritage homes from the 1860s through 1900s that were never built with insulation in mind. These homes need careful, experienced work because the building assemblies are different from standard wood frame construction and the wrong insulation approach can cause moisture problems in the stone walls. The mid-century suburbs that spread through the 1950s to 1970s are more standard but still heavily underinsulated by today's standards. Guelph's growth corridors around Stone Road and the east end brought newer builds that are better insulated overall, but still show the rim joist and crawl space gaps we see across Ontario.

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

Why Closed Cell Is the Right Choice for Guelph

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.

Does closed cell spray foam act as a vapour barrier? +
Yes. Closed cell spray foam at 2 inches or more meets Ontario Building Code vapour barrier requirements. This eliminates the need for a separate poly sheet in most applications and is one of the primary reasons closed cell is the correct choice for crawl spaces, rim joists, and exterior wall assemblies in Ontario's climate.

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.

We are not a franchise location reporting to a head office, not a call centre operation sending out subcontractors. That experience and accountability is the difference.
