Bonus room spray foam insulation in Red Deer deals with the room over the garage in this city's newer subdivisions. It is one of the most common calls we take from Red Deer homeowners, and it usually arrives after several other things have already been tried.
What has usually already been tried
By the time somebody looks at the envelope they have often closed vents elsewhere in the house to push more air upstairs, added a portable heater, had the furnace serviced, and in some cases had a duct run added. Occasionally somebody has put more insulation in the attic above the room, which is not where the problem is. None of it works for long because the room is losing heat downward into an unheated garage, and nothing done to the air supply changes what the floor is doing.
The floor over the garage, and its perimeter
The room sits on a floor structure with garage air underneath it and, at the outside edge, joist ends open to the outdoors where the garage wall meets the house. That perimeter band is the part that matters most and the part builders most often leave as a friction-fit batt. Air moves in at that band, through the floor cavity and around whatever insulation is there, which is why an inspection that finds insulation in the floor is not evidence the assembly is working.
The knee walls nobody mentions
Where a bonus room is partly in the roof space, its side walls are knee walls with attic on the other side rather than conditioned space. Those walls are frequently insulated but almost never sealed, and the attic behind them is at outdoor temperature. On a room that already has a cold floor, cold knee walls turn an uncomfortable room into an unusable one, and they are easy to miss because they look like ordinary interior walls from inside.
Doing it with the garage still in use
The work happens from the garage side, which means the room upstairs stays usable and the household is not displaced. The garage itself needs to be clear enough to work in and will be out of use for the duration, which for most Red Deer homes is a short and manageable interruption. That is worth knowing up front because it is the only real disruption involved.
Bonus Room Spray Foam Insulation Red Deer: Common Questions
We added insulation in the attic above and it did not help. Why? Because the loss is downward into the garage, not upward. The floor assembly and its perimeter are what matter.
What are knee walls and do we have them? Side walls of a room partly inside the roof, with attic behind them rather than heated space. If the room has sloped sections it very likely has them.
Do we have to move out? No. The work is done from the garage, so the Red Deer household stays in place and only the garage is out of use.
How much does bonus room spray foam insulation cost in Red Deer? Attic insulation has usually already been tried, which is why the floor over the garage and its perimeter is where this starts. The knee walls nobody mentions are the other half and they are priced separately.
How do I choose a bonus room spray foam contractor in Red Deer? Ask what knee walls are and whether yours have them. If the contractor cannot explain that on your house, they have not been into the space that is doing the damage.
