Ultimate Energy Efficiency
High-Performance Spray Foam Insulation in Jacksonville, FL
Protect your luxury home, drastically lower your energy bills, and seal out Florida's brutal humidity with our premium open-cell and closed-cell spray foam applications.
Open-Cell Foam: Maximum Energy Efficiency
Stop letting your expensive air conditioning escape through the roof. We specialize in full attic encapsulation using premium open-cell spray foam. By applying foam directly to the underside of your roof deck, we bring your attic into the conditioned envelope of your home, dropping attic temperatures by up to 40 degrees and drastically lowering your monthly energy bills.
- ✓ Full Attic Encapsulation & Insulation
- ✓ Significant Reduction in HVAC Workload
- ✓ Lower Monthly Utility Bills Year-Round
Closed-Cell Foam: Moisture Control & Rigidity
In Northeast Florida, humidity is your home's worst enemy. Closed-cell spray foam acts as a dense, 100% waterproof vapor barrier that completely seals out moisture, preventing mold and wood rot. Because of its rigid, glue-like density, closed-cell foam also significantly increases the structural sheer strength of your walls and roof, providing incredible protection during hurricane season.
- ✓ 100% Waterproof Vapor & Air Barrier
- ✓ Prevents Mold, Mildew, and Wood Rot
- ✓ Adds Structural Rigidity for Hurricane Protection
Sound Dampening & Crawlspace Sealing
True luxury means a quiet, comfortable home. Spray foam insulation provides incredible acoustic dampening, blocking out street noise, heavy rain, and neighbor disturbances. Additionally, for homes with raised foundations, we apply closed-cell foam directly to the subfloor, sealing out ground moisture and keeping your hardwood floors warm and perfectly preserved.
- ✓ Premium Acoustic Sound Dampening
- ✓ Subfloor & Crawlspace Encapsulation
- ✓ Blocks Pests and Outdoor Allergens

Spray Foam Insulation FAQ
Answers to the most common questions about upgrading your home's thermal envelope.
Do we need to leave the house during installation?
Yes. For your safety, we require the home to be vacant during the active spraying process and for a 24-hour curing period afterward. We use massive commercial ventilation systems to properly exhaust the space and ensure the air is 100% safe before you return.
Will spray foam really lower my energy bills?
Absolutely. By creating an airtight seal and bringing your attic into the conditioned envelope of the home, spray foam drastically reduces the workload on your HVAC system. Many of our clients see their monthly energy bills drop by 30% to 50%.
Does spray foam help keep bugs and rodents out?
Yes, specifically Closed-Cell foam. Because it expands and hardens into a dense, glue-like barrier, it seals off the tiny cracks and crevices in your walls and roof deck that pests use to enter your home.
Which is better: Open-Cell or Closed-Cell?
It depends on the application. Open-cell is excellent for interior walls and standard attic encapsulation because it is great for sound dampening and expands massively. Closed-cell is denser, 100% waterproof, and actually adds structural sheer strength to your roof, making it ideal for coastal hurricane protection and subfloors.
