Newer master-planned developments around the Boise area, Hidden Springs among them, give builders a chance to spec foam insulation correctly from the start instead of retrofitting later. That's the opportunity new construction foam work covers.
Boise Spray Foam Insulation Pros works directly with builders and owner-builders to schedule foam application between framing and drywall, using the right cell type for each zone of the building envelope.

FAQs
New Construction Spray Foam Insulation FAQs
What does spray foam insulation cost per square foot in the Boise area?
New construction pricing typically runs per square foot of building envelope, usually $1.50 to $3.00 depending on the cell type mix specified. Builders get volume consideration on larger projects.
Do I need a permit for spray foam insulation in a new build?
Insulation work is generally covered under the overall building permit for the project. An inspector sign-off is usually required before drywall goes up.
How do you coordinate with other trades on a build schedule?
We work directly with the builder's schedule, slotting foam application for the window after rough-ins are complete and before drywall starts. A quick site walk early in the build helps lock that timing in.
Can spray foam work for an owner-builder project, not just production builders?
We work with individual owner-builders the same way we work with production crews. The scheduling logic is the same either way.
What foam mix works best for a Treasure Valley climate?
A mix of open-cell in wall cavities and closed-cell at rim joists and below-grade areas covers most new builds well in this climate, balancing cost against moisture and air sealing needs.
