Spray foam insulation for new construction in Sherwood Park splits cleanly into two markets that get treated as one and should not be. There are the production builds going up in the newer phases of the hamlet, and there are the custom houses going up on acreages across Strathcona County, and almost nothing about them is the same.
A hamlet build and a county build are different jobs
A production house in a new phase is one of many on a schedule, with a builder's specification, a fixed sequence and a crew moving down the street. A county acreage house is a one-off, frequently owner-managed, often larger, usually with an attached or nearby shop, and answering to conditions the hamlet does not have. The first is about fitting into a schedule; the second is about getting the decisions right once. Quoting them the same way is how a county build ends up with a subdivision specification.
A house and a shop going up on the same yard
Most county builds around Sherwood Park include a detached shop, and it is very often being built in the same season as the house by the same people. Those two buildings want opposite things: the house is held at temperature continuously and the shop is heated when someone is in it, so one is about steady performance and the other is about how fast it recovers. Treating them as one specification because they share a site and a schedule is the most common way a county build ends up with a shop that costs too much to warm up. They belong in the same conversation and in two different scopes.
One day when everything hidden is open
The value is the access, not the product. On the day between the mechanical rough-in and the drywall, every rim joist, every wall to attic junction, the whole of any vaulted section and every penetration a trade has made are open at once. That day does not come again, and in this climate the assemblies it covers are the ones that would otherwise leak for nine months a year for the life of the building.
Sizing the mechanical to the building you are actually getting
A sealed shell needs less heating capacity than a leaky one and needs deliberate ventilation, and both decisions are made by somebody else at roughly the same time. If the mechanical is specified for a conventional house and the house is not conventional, the result is oversized equipment that short cycles. Telling the builder and the mechanical trade what the envelope is going to be is part of doing this properly.
Spray Foam Insulation New Construction Sherwood Park: Common Questions
We are building on an acreage rather than in a phase. Is it different? Yes, substantially. Different scale, different services, and often no gas main, which changes what the envelope is worth.
Does it change the furnace sizing? It should. A sealed house needs less capacity and needs planned ventilation.
When does it have to happen? Between the mechanical rough-in and the drywall. That window is the whole argument.
