Cottage spray foam insulation in Spruce Grove is different from the same job in most Alberta markets for one reason: the lakes are close. The recreational country west of here is under an hour away, which means these buildings are not shut for the winter in the way a distant cabin is.
Close enough to use in February
That changes the brief completely. A place three hours away gets closed in October and opened in May, so the objective is survival. A place forty minutes away gets used at Christmas, for a weekend in February, and whenever the weather is good, so the objective is that it can be brought up to comfortable in an afternoon by somebody who has just driven out with the family. Those are different buildings and they should be specified differently.
Recovery time is what actually matters
If a household is arriving on a Friday evening and leaving on Sunday, the number that counts is how long the place takes to become usable, not what it holds when nobody is there. That is governed by air leakage far more than by insulation depth, because a leaky building spends the whole warm-up heating air that is on its way out. It is why sealing a Spruce Grove owner's lake place changes the experience more than adding depth does.
Intermittent use is harder on a building than none
A place that is heated up and allowed to go cold repeatedly through a winter is going through a moisture cycle every time. Warm damp air is created, it meets cold surfaces, and it condenses; then the building goes cold again with that moisture in it. A cabin used every third weekend accumulates more of that than one shut from October, which is the opposite of what owners assume and it is worth knowing before deciding what to do.
Freeze protection is still the floor of the specification
Whatever else is wanted, the plumbing has to survive the weeks between visits, and on a building that is only warm intermittently that is a real question rather than a theoretical one. Where the lines run matters more than in a permanently heated house, and it gets established on the visit rather than assumed. On several of these the freeze exposure rather than the comfort is what justifies the work.
Cottage Spray Foam Insulation Spruce Grove: Common Questions
What changes if we use it in winter, not just summer? Then recovery is the number that matters, not what it holds empty, and sealing does more than depth.
Is using it in winter harder on the building? Yes. Repeated warm-ups and cool-downs put moisture through it. A building shut all winter does less of that.
What about the pipes between visits? That is the floor of any specification here, and where the lines run gets established on the visit.
