Garage spray foam insulation in Stony Plain covers two buildings that have almost nothing in common, because the older streets here have detached garages off the lane and the newer phases have them built into the front of the house.
Two kinds of garage, and only one of them touches the house
The detached building on an older lot shares nothing with the dwelling. Whatever is done to it benefits the garage alone, which makes the decision simple and entirely about what the owner wants from the space. An attached garage in a newer phase is the opposite: it shares a wall, usually a ceiling, and it sits inside the footprint of a conditioned house. Work on it improves rooms nobody was asking about. Establishing which of the two is being discussed changes the whole argument, and it is the first thing settled.
The slab under a building poured before anybody insulated one
The detached garages on the older streets here sit on slabs that were poured thin, without an insulated edge, and frequently without much preparation underneath. Thirty or forty winters later that slab has usually moved, and it holds the cold well into a warm spell because there is nothing between it and the ground. That matters more than owners expect, because a concrete floor at close to ground temperature will keep a building feeling cold long after the air in it has warmed up. It cannot be fixed after the fact and it does not need to be. It needs to be known about, so the building gets specified around it rather than in ignorance of it and nobody is surprised by a floor that stays cold.
Deciding what you actually want from a detached building
This is where money gets wasted in this town. There are two products and they cost very different amounts. Keeping a building above freezing so a vehicle starts and nothing bursts is a modest target achievable with a sealed shell and very little heat. Making it a comfortable workshop for winter evenings is a different specification entirely. Households frequently ask for the second and need the first, and quoting the first honestly is usually what makes the job happen.
Where the envelope line actually runs on an attached garage
The useful question on an attached building is not what to insulate, it is where the boundary of the heated house is meant to be. If the garage stays cold, the line runs along the wall and ceiling shared with the house, and those surfaces have to be built and sealed as exterior ones even though they look like interior partitions. If the garage is being brought inside the envelope, the line moves outward to the garage's own walls and door and the shared surfaces stop being critical. Choosing one and building it consistently is what works. Half of each, which is what most of these houses currently have, is the arrangement that fails. And wherever a Stony Plain garage is finished or worked in, the foam has to be covered by a thermal barrier, which belongs in the quote from the start. More on thermal barrier vs ignition barrier.
Garage Spray Foam Insulation Stony Plain: Common Questions
Does a detached garage at the back need a different approach? Then it is its own building and nothing you do to it changes the house. The decision is simpler.
What does it take just to get the car starting? That is a much smaller and cheaper job than a heated workshop, and it is usually what people need.
What if the door does not meet the floor? Deal with that first. It is the largest gap in the building and the cheapest to close.
