New Construction Spray Foam in Katy, TX
New construction is the best opportunity to insulate properly. With walls, attics, and crawl spaces open during framing, spray foam installation is straightforward, complete, and less expensive than any retrofit. Phantom Foam partners with builders and homeowners across Katy's master-planned communities to spec and install spray foam that delivers real-world performance, not just code compliance.

Why Code-Minimum Isn't Enough in Katy
Texas building code sets the floor for insulation performance — not the ceiling. A new home in Elyson or Cane Island built to minimum code with standard fiberglass batts will still have significant air leakage through top plates, around wiring and plumbing penetrations, and at rim joists. The fiberglass meets the nominal R-value requirement but does nothing to stop the air movement that accounts for 25–40% of typical energy loss.
Spray foam eliminates these pathways in the same step as insulation installation. A new home with spray foam attic and wall assemblies can often be built with a smaller HVAC system, which more than offsets part of the foam premium — while delivering meaningfully lower energy bills and better indoor air quality for the life of the home.

New Construction FAQ — Katy, TX
When in the construction schedule should we call you?
After framing is complete and the structure is weather-tight, before rough-in inspections and before drywall. This is the window to install open-cavity spray foam. We can also install at the pre-drywall stage if rough-ins are already in — just call us early to coordinate scheduling.
Do you work directly with production builders or only custom?
Both. We work with custom home builders, semi-custom builders, and owner-builders throughout the Katy area. For production builders, we can provide bid specs and volume pricing. Call to discuss your project volume and schedule.
Will spray foam let me right-size my HVAC?
Yes — a spray foam building envelope has a significantly lower heating and cooling load than a code-minimum home. A properly specified HVAC system for a foam home can be 15–25% smaller, with better dehumidification control and longer equipment life. We recommend working with your HVAC contractor on a Manual J calculation that accounts for the foam assembly.
Is spray foam worth the premium on a new Katy home?
For most homeowners, yes. The energy savings typically pay back the foam premium in 3–5 years. The comfort difference is immediate and permanent. And a well-insulated home in Katy's market has documented resale value compared to code-minimum construction. New construction is also the most cost-effective time to upgrade — retrofit costs significantly more.
