Commercial spray foam insulation in Stony Plain has a constraint no other town on this site has. A long-running programme of painted murals across the downtown buildings means the outside of a commercial property here is a civic asset, and that settles the method before anything else is discussed.
A frontage nobody is going to touch, and rightly
On a painted building the exterior is not a candidate for anything. It will not be stripped, it will not be re-clad, and no insulation is going on the outside of it. That is the correct position and it should be stated rather than negotiated, because an owner who has been offered exterior work by somebody is being offered something the town, the tenants and frequently the owner themselves would never accept. What it means practically is that the whole envelope conversation moves to the inside face of the wall.
Working from the inside, on whatever the wall turns out to be
Downtown buildings in Stony Plain are masonry, plank, or a mixture where somebody built onto something else, and the inside face is rarely flat or regular. That is the situation a sprayed layer suits and rigid board does not, because foam follows an irregular surface and adheres to it while board bridges the hollows and leaves a void behind itself. A void against a cold masonry wall is where water forms out of sight, so on this stock the choice of method is not a preference.
What the room costs, which is most of the job
The consequence of working from inside is that the finished space comes apart. Fixtures, casings, skirting, wiring on the surface, the drywall or plaster itself, and then all of it back afterwards. That is where the money is on one of these, and it is why this work belongs with a fit-out or a refurbishment rather than as a project of its own. An owner planning to redo a unit between tenants has an opportunity that will not come round again for years, and it is worth raising before the trades are booked.
Deciding how much of the building has to be done
Very few of these need the whole envelope. A downtown unit with a trading floor at the front and storage behind can be treated to the depth of the part people occupy, with a proper sealed boundary behind it, and left cold at the back. That is a fraction of the disruption and most of the benefit, and on a building where every square metre of interior work carries a making-good cost it is frequently the difference between the job happening and not.
Commercial Spray Foam Insulation Stony Plain: Common Questions
Can anything be done to the outside? No, and it should not be. On a painted building the work is all on the inside face.
Why is this dearer than a quote from elsewhere? Because the room has to be opened and put back. The foam is the small part of it.
Do we have to do the whole unit? Usually not. The front of the building properly, with a sealed boundary behind it, is common.
