Upgrade your home’s efficiency with air-sealing insulation that blocks heat, moisture, and allergens
Would you leave your windows wide open during an Arizona summer? Skipping attic air sealing before installing insulation is basically the same thing.
At Thermo Shield, we specialize in sealing the gaps, cracks, and openings in your attic that allow your conditioned air to escape — costing you comfort and increasing your utility bills.
Many existing homes have unsealed gaps—think plumbing penetrations, drop ceilings, and ductwork—that let valuable conditioned air escape. Traditional insulation simply can’t address those gaps alone. That’s where spray foam insulation comes in.
Spray foam doesn’t just insulate—it seals. Applied to the attic floor or the underside of the roof deck, it forms a continuous barrier that prevents air leaks, regulates temperature, and controls moisture.
Spray foam creates a tightly sealed, energy-smart envelope for Any Home.
Whether you’re upgrading an existing attic or building new, both open- and closed-cell spray foam options deliver long-term comfort and year-round energy savings.
Spray foam insulation performs in both attic types. In vented attics, it seals the floor to keep air from escaping.
In unvented attics, it’s applied to the roof deck to turn the attic into a conditioned space, helping reduce energy loss and improve HVAC efficiency.
The benefits?
Keep conditioned air inside, where it counts.
Homes lose an average of 25% of conditioned air through duct leakage—especially when ducts are in unconditioned, vented attics.
Spray foam stops that loss in its tracks by turning the attic into a conditioned zone. That means less HVAC strain, lower energy bills, and better indoor air comfort year-round.
