Open Cell Spray Foam Insulation Across Miami-Dade & Broward

Searching for open cell foam insulation near me in South Florida? Open cell spray foam insulation is a low-density, flexible polyurethane foam that expands aggressively at the moment of installation. As one of Miami's trusted open cell spray foam contractors, Atlas Insulation installs open cell foam spray insulation that locks itself into every void in the cavity - around wiring, plumbing, ductwork, and framing - creating a continuous air seal that fiberglass and traditional batts simply cannot match. The open cell spray foam insulation r value typically runs R-3.5 to R-3.8 per inch, and at 5–7 inches it meets or beats Florida code.

Because open cell foam insulation has a softer, more flexible structure than its closed-cell counterpart, it also performs exceptionally well as an open cell spray foam sound barrier. That is why wall open cell spray foam insulation is the default recommendation in homes where bedrooms back up to living rooms, where there is a home theater, or where a nursery shares a wall with a noisy laundry. It expands roughly 100 times its liquid volume, which means even unevenly framed cavities get fully sealed.

As a leading open cell spray foam insulation company, Atlas Insulation offers affordable open cell spray foam prices and fast open cell insulation service for residential and light-commercial properties throughout Miami-Dade, Broward, and Palm Beach County. Call (305) 858-3155 for a free quote open cell spray foam insulation estimate and learn the current open cell spray foam cost.

Best Applications for Open Cell Spray Foam in Miami:

  • Open cell spray foam roof insulation - Sprayed under the roof deck to bring the attic into the building envelope and stop heat gain at the source.
  • Wall open cell spray foam insulation - Bedrooms, home theaters, home offices, and nursery walls where soundproofing matters as much as thermal performance.
  • Cathedral & vaulted ceilings - Open cell spray foam fills sloped rafter bays where batts cannot conform.
  • Around plumbing & wiring - Open cell foam spray insulation wraps cleanly around obstacles that fiberglass leaves uninsulated.
  • Bonus rooms & over-garage spaces - Seals the floor cavity above unconditioned garages with reliable open cell spray foam insulation r value performance.
  • New construction framing - Maximum coverage installed during the build process by experienced open cell spray foam contractors.

Frequently Asked

Open cell spray foam answers, in plain English.

Open-cell spray foam is most commonly used for attic insulation under the roof deck, soundproofing interior walls between bedrooms and home theaters, sealing around plumbing chases, and insulating cathedral ceilings. Its expansion fills every gap in the cavity, which is why it outperforms fiberglass batts on air sealing.
Open-cell spray foam significantly reduces airborne noise transmission. Its lower density and open-cell structure absorb sound waves rather than reflecting them, which makes it one of the best choices for interior walls between bedrooms, home theaters, nursery rooms, and any space where quiet matters.
The open cell spray foam insulation r value typically rates around R-3.5 to R-3.8 per inch. While that is lower per inch than closed-cell spray foam (around R-6.5), open cell foam insulation can be installed at greater thickness - typically 5 to 7 inches in a 2x6 wall - giving total R-values that meet or exceed Florida code for residential walls and attics.
Yes, when installed correctly. Open-cell foam is vapor-permeable, meaning moisture can pass through and dry to either side, which actually helps prevent trapped condensation in many Miami wall and roof assemblies. Atlas Insulation will assess your specific assembly and ventilation before recommending open-cell vs. closed-cell.
As one of Miami's open cell spray foam contractors, Atlas Insulation installs open cell spray foam insulation starting at 99¢ per square foot. Final open cell spray foam prices depend on cavity depth, total square footage, accessibility, and any existing insulation removal.
