Sherwood Park is a large urban community immediately east of Edmonton, sitting next to one of the province's densest concentrations of refining and petrochemical industry. Foam quotes here come in two flavours - suburban residential and heavy industrial - and the two have almost nothing in common except the unit they are priced in. Spray foam insulation cost in Sherwood Park is two different calculations depending on the building type.
The unit: board feet
A board foot is one square foot at one inch of thickness, and foam is priced on it. Your number is area times thickness times product, with thickness set by the R-value the assembly must reach. Ask for the thickness in writing. Without it, comparing quotes is comparing scopes you cannot see.
The residential picture
The recurring residential jobs are basement development, bonus rooms over garages, and rim joists. Basements are closed-cell work because they are below grade - the material resists moisture rather than absorbing it, which is a durability argument before it is a thermal one, and two inches gets roughly R-12 to R-14 with three to four inches reaching R-18 to R-28 where the cavity allows. Interior partitions where the goal is quiet are open-cell work, cheaper and better suited to it.
Industrial adjacency changes everything about a quote
Refinery Row and the surrounding industrial base is steel building stock, and on steel the problem is condensation rather than conduction. Warm interior air meets a cold panel and gives up its moisture there; foam bonded directly to the metal removes that surface. Thickness is driven by dew-point control, not by a residential R-target. Access, scheduling, safety requirements and site conditions are all different, and the quote will reflect that rather than a residential rate.
The prep question is where quotes diverge
Two numbers for the same basement usually differ on one of three things: the thickness priced, the product chosen, or what is included before anyone sprays. Removal of existing insulation, cutting out a failed vapour barrier, masking, and the thermal barrier code requires over foam in occupied space - 12.7 mm drywall or an approved intumescent coating - are all genuine costs. A crawl space entered only for service can take an ignition barrier instead, which is cheaper; deciding what the space will be used for is therefore part of pricing it.
Why nobody should quote this over the phone
Depth, access and prep are things you look at. A number produced from a description is a guess with a decimal point in it, and it is the main reason foam pricing has a reputation for moving after the crew arrives. Use the calculator to plan the volume, then have someone see the building.
A residential rate and an industrial rate are not comparable
If you are pricing work on a house and work on a commercial or industrial building, expect two quotes built on different logic - and be suspicious of one rate applied to both. A residential job is scoped to an R-value target with domestic access. An industrial job on steel is scoped to dew-point control, with site safety, scheduling and working-at-height conditions that a driveway does not have. Those are not the same trade problem wearing different clothes, and a contractor who prices them identically has not thought about one of them.
Spray Foam Insulation Cost Sherwood Park: Common Questions
Why are there two totally different quotes for my properties? Because a suburban house and an industrial building are different trade problems. One is scoped to comfort and an R-value, the other to dew point with height, safety and scheduling constraints.
What is the most common residential job here? Basement development, a bonus room over a garage that will not hold heat, and rim joists. All three are sealing jobs rather than depth jobs.
Can you give a number over the phone? Not one that will hold. Depth, access and prep are things somebody looks at, and a figure produced from a description is the main reason foam quotes have a reputation for moving.
