Wall spray foam insulation in Olds is applied where a wall is open, during a renovation, a basement development or a build. On this stock it is rarely the first thing worth doing, and saying that clearly is more useful than quoting it.
Worth doing when the wall is open anyway
That is the rule and it holds on almost every house here. During a renovation, a window replacement, a re-clad or a basement development, the cavity is accessible and doing it properly adds very little to work that is happening regardless. Outside those moments, opening a sound finished wall purely to insulate it is money that would do considerably more at the band or the ceiling plane. Nobody should take an Olds house apart to reach a wall.
Which walls in a let house actually get opened
On a rental the openings happen for their own reasons and they are predictable: water damage behind a bathroom, a kitchen being replaced between tenancies, a wall moved to make another bedroom, or repair after something failed. Those are the moments, and a landlord who knows this work is available and cheap at that point gets it for a fraction of what a standalone job would cost. A landlord who does not, closes the wall again and loses the chance for another twenty years.
Where a wall leaks whatever is inside it
Not through the middle of the cavity. At the top plate where the wall meets the ceiling plane, at the bottom where it meets the floor system, around window openings where the original packing has shrunk, and at every electrical box. Those are air paths rather than resistance problems. It is why a wall that is technically insulated can still feel cold and why adding material without addressing them disappoints.
The wall to an attached garage is the exception
One wall is always worth treating when it is open, on any house of any age. 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, the sealing and the separation are handled together, because doing one without the other is the version that fails and it is not a version worth paying for. On a let house it is also the one wall where the requirement does not depend on anybody's preference, which makes it the easiest thing to get agreed.
Wall Spray Foam Insulation Olds: Common Questions
Should we insulate the walls? Only when they are open for another reason. Otherwise the band and the ceiling do more per dollar.
Is a bathroom renovation a good time to spray foam the wall? Then that wall is open and this is cheap. It is the moment worth using.
Is any wall always worth it? The one shared with an attached garage, because it is doing two jobs at once.
