Wall spray foam insulation in Ponoka is applied where a wall is open, during a renovation, a basement development or a build. On a stock that spans a century the first question is not how to insulate the wall, it is what is in it now.
What is in the wall depends entirely on when it went up
On the oldest Ponoka houses the answer is frequently nothing at all, or something that was never insulation in the first place. Mid-century houses have a shallow cavity with whatever was standard that decade. Newer houses have a full depth of batt and a vapour control that is doing its job. Those are three different starting points and the right action ranges from a full treatment to leaving the wall alone entirely.
Where a wall actually leaks, whatever is in it
Not through the middle of the cavity. It leaks at the top plate where the wall meets the ceiling plane, at the bottom where it meets the floor system, around window and door openings where the original packing has shrunk, and at every electrical box. Those are air paths rather than resistance problems, and they are what a sprayed application closes when a wall is open. Adding material to a cavity while leaving those untouched is the version that disappoints.
Only when the wall is already open
This is the practical rule and it saves people money. During a renovation, a window replacement, a re-clad or a basement development, the cavity is accessible and doing it properly costs very little extra. Outside those moments, opening a finished wall purely to insulate it is money that would do considerably more at the band or the ceiling plane. Nobody should take a Ponoka house apart to reach a wall. The exception is a wall that is already coming off for a reason of its own, and in that case the marginal cost of doing it properly is small enough that it should not be a separate decision.
The wall between a house and an attached garage
One wall is always worth treating when it is open, regardless of the age of the house. The wall between living space and an attached garage is an exterior wall doing a separation job at the same time, keeping garage air out of the house. Where that assembly is opened for any reason, sealing and separating are handled together, because doing one without the other is the version that fails.
Wall Spray Foam Insulation Ponoka: Common Questions
Should we insulate our walls? Only when they are open for another reason. Otherwise the band and the ceiling do more for the money.
What is in an older wall here? It ranges from nothing to a full cavity depending on the decade, and it gets looked at rather than assumed.
Is any wall always worth it? The one shared with an attached garage, because it is doing two jobs at once.
