Bonus room spray foam insulation in Carstairs is work on the room over the attached garage, and in this town the space underneath it has a daily rhythm that makes the room behave worse than the same room would elsewhere.
The garage below is emptied at the coldest hour
In a commuter household the vehicles pull out early and the overhead door opens onto the coldest part of the morning to let them go. Whatever warmth the garage had accumulated overnight leaves in that minute, and the space then sits at close to outdoor temperature all day with nothing to bring it back. The room above is sitting on that, which is why the floor is at its worst on exactly the mornings the household notices it most.
The door opening twice a day is the reason it never recovers
This is worth separating from insulation depth, because it is a different mechanism. A garage that was simply unheated would drift toward some middling temperature. A garage whose largest wall opens completely twice a day is flushed with outside air on a schedule, so it never drifts anywhere. No amount of insulation in the garage walls changes that, and it is why the correct target in a Carstairs house is the floor of the room above rather than the garage itself.
The floor and its perimeter, reached from below
The work is done from the garage with the ceiling open, and the part that decides the result is the perimeter where the floor structure meets the exterior wall. That edge is where outside air gets into the floor cavity and moves along under the room, and it is the part most often left short because it is awkward to reach. Treating the middle of the floor and missing that edge produces a room that is better and still not right.
The other three sides nobody mentions
A room over a garage is usually exposed on more sides than any other room in the house, with outside air on two or three walls and often a roof directly above. In a house that is set back all day those surfaces are all losing at once and the room has no neighbour to borrow from. Where the ceiling above the room is accessible from the attic, treating it at the same visit is straightforward and it is frequently the difference between a room that is usable in the evening and one that is not.
