Leduc is where Alberta's modern oil industry started, and the city still sits at a crossroads - the international airport on one side, the Nisku energy park on the other, and a residential community in between. About 39 percent of its homes were built before 1991. That mix means a spray foam contractor here works on houses and on large light-industrial buildings in the same week. Spray foam insulation in Leduc is asked for on houses and on large light-industrial buildings in the same week, and the two share almost nothing but the unit of pricing.
What the airport corridor is made of
Warehousing, logistics and service buildings around the corridor are overwhelmingly steel-framed and steel-clad. On those, the thing owners actually call about is water: condensation forming on the underside of a cold roof deck and dripping onto whatever is stored below. That is not a roof leak and it will not be fixed by patching one. It is warm interior air reaching a cold surface, and the durable answer is closed-cell foam bonded directly to the panel so the cold surface is no longer exposed to the interior air.
Houses, and where to start on them
The residential stock splits fairly evenly between pre-1991 and newer. On the older side, the best first jobs are the ones that address air movement rather than adding depth - rim joists and the attic ceiling plane, both small areas with disproportionate results. On the newer side, basement development and bonus rooms over garages are the recurring requests, and both are open-framing work with very little prep.
Choosing the product rather than defaulting to one
Closed-cell at roughly 2 lb per cubic foot gives R-6 to R-7 per inch, resists moisture, and becomes a vapour retarder at about 38 mm - it belongs below grade, on exposed assemblies and on steel. Open-cell at roughly half a pound gives R-3.5 to R-3.8, is vapour-permeable and interior-only, and is both cheaper and better where the objective is sound. A contractor specifying the dense product everywhere is selling density rather than performance, and in an attic with headroom the honest answer is frequently the cheaper foam at greater depth.
What every job has to satisfy
Medium-density foam meets CAN/ULC-S705.1 as a material and is installed to CAN/ULC-S705.2 by a certified installer. In occupied space the foam needs a thermal barrier over it - 12.7 mm drywall or an approved intumescent coating - while attics and crawl spaces reached only for service can use an ignition barrier. On commercial occupancies the requirements move with the classification, so the authority having jurisdiction is worth confirming before the spec is locked.
Spray Foam Insulation Leduc: Common Questions
If I can only afford one job, which one? The rim joist. It is a continuous unsealed band around the whole house, small in area, reachable from an unfinished basement, and the main floor feels different immediately.
Why not the attic first? Because in most houses the heat leaves as air through the ceiling penetrations rather than by conduction through the insulation. Adding depth over an unsealed ceiling leaves the actual leak untouched.
Do you do the airport and Nisku buildings? Yes. Those are steel and quoted on condensation control rather than a residential R-value target.
