Spray foam insulation for new construction in Leduc happens on ground where an airport influences what gets built and where. That is unusual, and for anybody putting up a house here it is worth understanding as a design input rather than a piece of trivia.
The airport shapes what goes where
Land use around a major airport is planned around it, which pushes residential development into particular areas and industrial and commercial development into others. For a house being built here that means the surroundings are more predictable than they would be in a town growing without a constraint, and it also means the exposed elevations and the noise environment of a new phase are known at the point of design rather than discovered afterwards.
Designing an envelope with the noise in mind at the same time
This is the useful part and it gets missed. The same measures that seal a house against air movement also make a measurable difference to airborne sound, and the assemblies involved are largely the same ones. A house being built where overflight is a fact of the location can have that dealt with during construction for very little additional cost, whereas doing it afterwards means opening finished walls. It is worth raising with the builder before framing rather than after the first summer, because once the drywall is on, the same result costs several times as much and disrupts a finished house.
One day when everything hidden is reachable
On any build, the day between the mechanical rough-in and the drywall is when every rim joist, every wall to attic junction, every penetration a trade has made and the whole of any vaulted section are open at once. That day does not come again. With a heating season running the better part of nine months and no thaw in the middle of it, those assemblies are the ones that would otherwise leak for the entire life of the building.
Telling the mechanical trade what the shell will be
A sealed house needs less heating capacity than a conventional one and needs deliberate ventilation, and both decisions are being made by somebody else at roughly the same time. If equipment is specified for a leaky house and the house is not leaky, the result is oversized plant that short cycles and an owner who paid for capacity they cannot use. On a Leduc build it is an easy conversation to have early and an expensive one to skip.
Spray Foam Insulation New Construction Leduc: Common Questions
Can the noise be dealt with while we build? Yes, and far more cheaply than afterwards, because it uses largely the same assemblies as the air sealing.
Does this 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.
