Bonus room spray foam insulation in Didsbury usually means something different from what it means further down the corridor, because the older part of this town has very few attached garages for a room to sit on top of.
Here the extra room is in the roof, not over a garage
In the newer subdivisions this page is about a floor over an unheated garage. In the older streets of Didsbury the equivalent room is upstairs in the roof itself: a converted attic, a room over a back addition, or a half storey that was finished at some point after the house was built. The complaint from the household is the same, which is that the room is unusable at both ends of the year, but the reason is different and so is the work.
A conversion done without an assembly behind it
These rooms were very often finished by an owner rather than built as part of the house. Board went straight onto the rafters, or batts were pushed into a cavity too shallow to hold them, and the knee wall was built with nothing behind it at all. There may be no ventilation path, no air barrier, and no continuity where the sloped ceiling meets the flat one. The room looks finished and behaves like an uninsulated roof, which is exactly what it is.
The knee wall space is the part doing the damage
Behind the short vertical walls at each side there is a triangular void running the length of the room, open to the eaves at the bottom and often open into the floor structure as well. Outdoor air gets into it, moves along under the floor of the room and comes up through the gaps at the skirting. Treating that void, rather than adding more material to the sloped ceiling, is what changes how a Didsbury room of this kind feels to sit in.
Getting at it without taking the room apart
This is the awkward part and it deserves an honest answer. Some of these can be reached through hatches, through the eaves, or from the room next door. Others cannot be done properly without opening a surface, and where that is the case it is better said at the quoting stage than discovered halfway through. Where a room is going to be redecorated anyway, that is the moment to do it, and pairing the two is how most owners here get it done affordably.
Bonus Room Spray Foam Insulation Didsbury: Common Questions
What if the room is upstairs in the roof, not over a garage? That is the usual arrangement here, and it is the version this page is about.
Why is it cold at the edges of the room? The void behind the knee walls is open to outside air and runs under the floor.
Can it be done without wrecking the room? Sometimes. Where it cannot, that gets said before the work starts, not during it.
How much does bonus room spray foam insulation cost in Didsbury? Here the extra room is in the roof rather than over a garage, so the knee wall space is the part doing the damage and the sloped ceiling is next. A conversion done without an assembly behind it is the usual finding.
How do I choose a bonus room spray foam contractor in Didsbury? Ask what they find behind the knee walls before quoting. A room in the roof is a different job from a room over a garage, and a quote that does not know which one you have is not a quote.
