Ceiling spray foam insulation in High River is work on a surface that sits at the opposite end of the building from where all the attention went, which is exactly why it is worth looking at now.
The furthest thing from where the work happened
Rebuild scopes on a High River house worked upward from the lowest damaged point and stopped where the damage did. That means the ceiling plane was outside every one of them, and on a house whose lower level is a decade old the ceiling is whatever it was before any of that started. It is the least examined surface in these buildings and it is also, on most houses of this stock, the one carrying the largest single share of the losses.
What a ceiling of this era has in it
About 36% of the housing here predates 1991 and the rest is mostly not far behind, so the typical ceiling is a flat plane with blown or batt insulation to the standard of its decade lying on top of a surface nobody ever sealed. The openings are the ordinary ones: the hatch, the bathroom fans, the light fittings, the top plates of interior walls, and wherever a stack or a chimney passes through. Together they move more air than the insulation is holding back.
Where a chimney or a stack passes through it
The largest single opening in most of these ceilings is not the hatch, it is wherever something vertical goes through the plane. A chimney that has been decommissioned and left in place, a plumbing stack, an old furnace flue that was replaced with a side-vented appliance and never sealed at the ceiling. Each of those is a permanent hole with a clearance around it that was required at the time and never closed afterwards, and unlike a light fitting it runs the full depth of the insulation. On a High River house where the mechanical was renewed during a rebuild, an abandoned flue through the ceiling is a common leftover and it is worth looking for specifically.
A job that does not disturb a rebuilt room
This is the practical reason it is usually the right next item on a High River house. Almost all of a flat ceiling can be treated from the attic with nobody moving out of a room, nothing coming off a wall and nothing to make good afterwards. On a property where a great deal has already been rebuilt that matters as much as the result does: the scope is bounded, it can be assessed before anybody commits, and it leaves the recent work entirely alone. It is also the reason this tends to be the item households here actually proceed with, rather than the one that sits in a folder.
Ceiling Spray Foam Insulation High River: Common Questions
Would the rebuild have touched the ceiling? Almost never. Scopes worked upward from the damage and stopped well below it.
Can it be done without disturbing the rooms? Most of a flat ceiling, yes, entirely from the attic side.
Why is the back room colder than the rest? Look at the step where an addition's ceiling meets the original. That face is rarely insulated.
