Thermal Efficiency Systems

Smarter Insulation. Greater Comfort. Lower Energy Bills.

From new construction to existing homes, Gray's Insulation delivers premium spray foam, fiberglass, and air sealing solutions that improve comfort, reduce energy costs, and protect your investment for years to come. Every installation is tailored to your building—not a one-size-fits-all approach.

Lower Energy Bills

Reduced heating & cooling cost by 30% or more

Air Sealed

Eliminates drafts & air leaks

Built to Last

Lifetime performance

High-Performance Foam

Open-Cell & Closed-Cell Precision

Spray foam insulation expands in place to seal every gap, crevice, and structural cavity, eliminating thermal bridging while dramatically reducing monthly heating and cooling energy loss.

Maximum R-Value. Maximum Protection.
Closed-cell spray foam delivers approximately R-7 per inch while creating a rigid air and moisture barrier that increases structural strength and energy efficiency. It's the premium choice for crawlspaces, metal buildings, exterior walls, commercial projects, and anywhere maximum performance is required.

Closed-Cell Spray Foam-

Open-Cell Spray Foam-

Expand Comfort. Eliminate Energy Loss.
Open-cell spray foam expands to completely fill every gap, crack, and cavity, creating a seamless air barrier that improves comfort, reduces outside noise, and lowers heating and cooling costs. It's the ideal insulation solution for homes, attics, and interior wall systems.

Traditional & Specialized

Fiberglass & Attic Retrofits

Targeted thermal upgrades and clean-out services tailored for existing homes, custom framing, and interior soundproofing.

Fiberglass Batt Installation

Blown-In Attic Top-Offs

Safe Insulation Removal

Precision-cut friction fit batts tailored for wall cavities, floors, and crawlspaces, delivering reliable thermal defense and room-to-room acoustic control.

Loose-fill virgin fiberglass blown evenly across attic floors to restore degraded R-values, eliminate cold ceiling spots, and stabilize seasonal indoor temperature.

HEPA-filtered vacuum extraction for damaged, rodent-compromised, or outdated insulation, leaving attic spaces clean, disinfected, and ready for modern thermal upgrades.

Heavy-Duty Applications

Commercial & Metal Buildings

Warehouse & Facility Retrofits

Large-scale thermal insulation upgrades designed to regulate interior storage temperatures, lower commercial HVAC loads, and protect climate-sensitive inventory across regional facilities.

Metal Buildings & Barndominiums

Direct-to-metal closed-cell spray foam application engineered to stop sweating, prevent structural condensation, and create an airtight thermal envelope for steel shops and modern barndominiums.

Closed-cell spray foam doesn't just insulate—it becomes part of the structure. Its high-density composition bonds to the framing to help increase rigidity, improve building durability, and provide long-term structural reinforcement.
