Red Deer's housing splits close to evenly between pre-1991 and newer stock - about 50 percent either side - which means there is no single right answer for the city and the open-cell question has to be settled assembly by assembly. That is a better conversation than a product pitch, so here is the decision as a contractor should present it. Open cell spray foam insulation in Red Deer is chosen by three questions rather than by price.
The three questions that decide it
- Does this surface face weather, ground or steel? If yes, it is closed-cell. Open-cell is vapour-permeable and absorbs moisture, so it has no business below grade, in a crawl space, on a rim joist or bonded to a metal panel.
- Is the cavity depth fixed? If yes, density wins. Closed-cell puts R-6 to R-7 per inch into a stud bay where open-cell puts R-3.5 to R-3.8. In a 2x6 wall that difference decides it.
- Is the objective sound rather than heat? If yes, it is open-cell. At about 0.5 lb per cubic foot it stays soft and open, and that structure absorbs airborne noise better than a rigid foam.
Where that lands in a typical Red Deer house
The basement is closed-cell, because it is below grade. Exterior walls are closed-cell, because the cavity is fixed and the surface faces weather. Interior partitions, the home office, the wall against an attached garage and any media room are open-cell, because the objective is quiet. The attic is the one that is genuinely open: R-38 is about eleven inches of open-cell or six of closed-cell, and where the depth exists the cheaper material is the better buy.
Commercial and industrial is not the same call
Riverside, Edgar, Northlands, Queens Business Park, Burnt Lake and the Gasoline Alley corridor carry a lot of steel buildings, and steel is closed-cell without discussion - the problem is a cold panel that warm air condenses on, and only a dense adhered foam removes that surface. Interior office fit-outs inside those buildings can still be open-cell for the acoustic partitions.
Code applies to both products
Foam facing occupied space needs a thermal barrier over it, usually 12.7 mm drywall or an approved intumescent coating; attics and crawl spaces entered only for service can take an ignition barrier. Open-cell is covered by its own CAN/ULC standard, while CAN/ULC-S705.1 is the medium-density material standard and S705.2 governs installation by a certified installer.
Open-Cell Spray Foam Insulation Red Deer: Common Questions
How do I choose between the two foams? Ask whether the surface faces weather, ground or steel; whether the cavity depth is fixed; and whether the goal is sound. The first two point to closed cell, the third to open cell.
Which rooms in a house suit it? Interior partitions, the home office, a media room and the wall against an attached garage.
Can it be used in a commercial fit-out? The interior acoustic partitions inside a steel building, yes. The building envelope itself is closed-cell work.
