Cottage spray foam insulation in Beaumont is an unusual enquiry for an obvious reason: there is no lake here and no recreational stock. What the enquiries actually concern is a seasonal building on a property, or a second place somewhere else that a household here is trying to sort out.
A town with no cottages and plenty of seasonal buildings
What turns up on properties around Beaumont is a guest suite over a detached garage, a converted outbuilding used through the summer, a studio at the back of an acreage, or a small dwelling on a farm yard that somebody lived in two generations ago. Every one of those has the same defining characteristic as a lake cottage even though it looks nothing like one: it is unheated and unoccupied for most of the year, and it is judged on the weekend somebody opens it.
Absence is the condition these buildings are designed against
The mistake is to specify one of these like a house. A house is occupied and heated, so insulation depth governs how much that costs. A building that is closed from October to May is not being heated at all, so depth is doing very little and the air moving through the shell is doing everything. What that air carries is moisture, and it deposits it wherever the temperature suits, which is how a building that is merely cold in November becomes a building that is damp in April.
Snow that banks against a building nobody visits until spring
A building that is shut in October has nobody clearing anything around it. Snow drifts against whichever side takes the wind and stays there, and on a small outbuilding that means the bottom metre of one wall spends five months in contact with something that is wet whenever the temperature rises. Then it all releases at once in a warm week, into ground beside a foundation that is usually shallow and frequently just a pad. That is why the damage on these buildings is so often at the base rather than anywhere an owner would think to look, and it is why the first thing checked on a seasonal building is the bottom of the wall and what the ground does with the melt, before anything about the envelope above it is discussed.
What it means to open it up in April rather than October
The useful outcome is worth naming, because it is not comfort and it is not a heating bill. It is opening the door in spring to a building that smells the way it did when it was shut, with nothing soft gone musty, no bloom on tools or fabric, and no need to spend the first weekend of the season airing it out. On a Beaumont property that is what this work buys, and it is achieved by sealing the shell rather than by adding depth to it.
Cottage Spray Foam Insulation Beaumont: Common Questions
What if it is not really a cottage? It does not need to be. Any building that is shut for most of the year behaves the same way.
Should we insulate it deeply? Only if it is being held above freezing. If it is drained and closed, sealing matters far more.
Why does it smell when we open it in spring? That is air moving through it all winter and depositing moisture. It is what sealing fixes.
