Thermal Shield · Middle Tennessee

Control the
envelope.

We plan and install spray-foam assemblies for Middle Tennessee homes, shops, pole barns, and commercial buildings — sealing the roof, shell, and foundation so conditioned air stays where it belongs.

The Problem

Heat, humidity, and the air you can't see.

Most comfort and moisture problems in a building come down to one thing: an envelope that isn't sealed.

Air leakage

Gaps and cracks let conditioned air escape and outside air in. Fiberglass and batt insulation slow heat movement but do not stop air — so the envelope leaks.

Humidity & condensation

Middle Tennessee humidity enters walls, attics, and crawlspaces, then condenses on cool surfaces. Over time that moisture feeds mold, mildew, and rot.

Uneven comfort

When the envelope leaks, some rooms run hot while others stay cold. HVAC works harder to keep up, and the building never feels settled.

Pole Barns · Post-Frame

Turn a pole barn into a building that works.

Uninsulated post-frame buildings swing wildly in temperature and sweat with condensation. Spray foam creates a continuous envelope that helps control condensation, stabilizes comfort, and protects what you store — whether it is a workshop, garage, equipment, or living space.

  • Condensation control on metal roofing and framing
  • Comfortable workshops, garages, and conditioned space
  • Sealing around posts and purlins for a true envelope
  • Assembly planning around how you use the building

How We Plan the Envelope

Assess. Specify. Install.

A deliberate process — not a one-foam-fits-everything approach.

01

Assess the building

We walk the structure, review the assembly, and identify where air, moisture, and heat are moving. No blanket recommendations — we start from what your building actually needs.

02

Specify the right assembly

We recommend where open-cell, closed-cell, or a combination fits each part of the envelope, sized to your cavity depth, climate, and goals.

03

Install and verify

We prep and protect the site, apply the foam, and walk the finished work with you to confirm coverage before cleanup.

Open Cell vs. Closed Cell

The right foam for the assembly.

Both foams air-seal. The difference is density, R-value per inch, moisture behavior, and cost — so the choice depends on the assembly, not the building.

Open Cell

Structure
Soft, flexible, expansive
Typical R-value
~R-3.5–4 per inch
Vapor behavior
Vapor-permeable
Best fit
Large cavities, sound control, value

Closed Cell

Structure
Dense, rigid, controlled lifts
Typical R-value
~R-6–7 per inch
Vapor behavior
Class II vapor barrier
Best fit
Tight cavities, moisture, high R in less space

Questions

What an estimate includes — and what to expect.

Straight answers to the questions we hear most.

Cost depends on square footage, foam type, and access. We provide a site-specific estimate after a free assessment — no blanket numbers.
