New Construction Insulation

If you're building a new home in Oklahoma, you have exactly one chance to get the insulation right. Once the drywall goes up, the walls are sealed — and whatever insulation is in there is what you're living with for decades. Spray foam is the only insulation that fills every gap, seals every penetration, and creates a true air barrier in a single application.

Why Builders Choose Spray Foam

Builders who spec spray foam see immediate benefits:

Fewer callbacks — The #1 warranty complaint for new homes is comfort: rooms that are too hot, too cold, or drafty. Spray foam eliminates these problems because it eliminates the air leaks that cause them. Fewer callbacks means lower warranty costs and happier homeowners.

Smaller HVAC systems — A tighter building envelope means less heating and cooling capacity is needed. Many spray foam homes can be built with smaller, less expensive HVAC systems that still deliver superior comfort. That's a real cost offset against the insulation upgrade.

Better HERS scores — Spray foam homes consistently score 50–70 on the HERS Index versus 80–100 for code-minimum construction. Lower scores mean electric company rebates for the homeowner, energy-efficient mortgage qualification, and a concrete marketing advantage for the builder.

Passing blower door tests — Oklahoma's energy code requires blower door testing for new construction. Spray foam homes pass consistently because the insulation IS the air barrier. No need for separate air sealing, caulking, or additional labor to hit the ACH50 requirement.

The New Construction Process

We coordinate directly with your builder or GC to schedule spray foam at the optimal point in the construction timeline:

1. Pre-spray meeting — We review plans, discuss R-value requirements, and identify any special considerations (cathedral ceilings, bonus rooms, garage adjacency). 2. Rough-in complete — We spray after plumbing, electrical, and HVAC rough-in are finished but before drywall. All penetrations are sealed as the foam goes on. 3. Inspection-ready — After spraying, we trim any excess foam so the walls are flush for drywall. The insulation is ready for inspection. 4. Blower door testing — We offer blower door testing to verify air tightness before drywall, allowing any issues to be addressed while walls are still open.

Open Cell vs. Closed Cell for New Construction

Exterior walls — Open cell at 3.5" (2x4 wall) or 5.5" (2x6 wall) is the most common choice. It fills the cavity completely, provides excellent R-value, and costs less than closed cell. Closed cell is recommended when you need the vapor barrier properties (below-grade walls, areas with moisture exposure).

Attic/roof decking — Open cell at 5.5–6" on the underside of the roof decking brings the attic into the conditioned envelope. This is the standard approach for spray foam new construction.

Crawl spaces — Closed cell on the crawl space walls provides insulation and vapor barrier in one application.

For Homeowners Building Custom

If you're building a custom home and your builder isn't planning to use spray foam, ask why. The upgrade cost is modest relative to total construction cost, and the performance difference is dramatic. We're happy to meet with you and your builder to discuss the options and provide pricing for your specific plans.
