What our commercial spray foam insulation work includes
Scope also covers open-cell spray foam insulation and closed-cell spray foam insulation.
- Metal building roof decks and walls. Closed-cell foam is usually the fit here because it resists moisture and adds thermal performance per inch on steel that can run below the dew point.
- Interior demising and sound-sensitive walls. Open-cell foam fills the cavity and helps attenuate airborne sound, and it costs less per inch than closed-cell for interior, conditioned space.
- Rim joists, penetrations, and transition details. Either foam type fills irregular gaps at transitions where sealing continuity matters more than raw R-value.
- Standard framed office or retail walls. A plain framed wall with good access and no moisture exposure often does not need foam's air-sealing capability or its cost per inch.
Buildings we install it in
We install it in warehouses and distribution centers, factories and plants, cold storage facilities, and office buildings, along with other commercial and industrial property.
Projects we scope differently
- A standard framed wall with easy access and no moisture or air-sealing problem to solve is usually a poor fit for foam's cost per inch.
- A roof or wall that is actively leaking should not be sprayed over.
- Large, open ceiling planes where loose material can be blown in quickly are rarely cost-effective to fill with foam.
New construction and retrofit coordination
On new construction. On new construction, spray foam usually goes in after the building is dried in and rough mechanical, electrical, and plumbing work is through the cavity, since foam has to bond to a clean substrate and cover the framing and penetrations in one pass. We confirm which foam type the assembly calls for, mask adjacent surfaces and equipment, and apply to the specified thickness. Inspection typically follows before the wall or ceiling closes up, since foam is not visible again once finishes go on.
In an existing building. In an existing building, the cavity has to be opened or already accessible before foam goes in, so the work usually follows a demolition step or targets an area already exposed for another trade. We isolate the work area, mask finishes and equipment nearby, and run ventilation during application and through the manufacturer's stated re-entry period before anyone without protective equipment returns to the space. Occupied floors near the work zone are coordinated with facility staff ahead of the date.
Access, phasing, and safety on site
- Containment. Overspray drifts, and cured foam does not come off finishes, equipment, or flooring once it sets. We mask and cover the whole work zone, not just the surface being sprayed, before application starts.
- Safety. Spray foam application involves isocyanates, so the work area is ventilated during application and kept clear of other trades and occupants for the re-entry period the manufacturer states for that product.
- Scheduling. Because of the required re-entry period, spray foam work is usually sequenced so no other trade needs the space until ventilation clears it, which shifts the days immediately around the spray date more than other systems.
- Fire-rated facings and barriers. Spray foam is a foam plastic, so the building code (IBC Section 2603) generally requires a thermal barrier between it and the building interior, commonly 1/2-inch gypsum wallboard, unless the specific assembly has been tested and approved without one. That applies to open-cell and closed-cell alike. Where foam plastic sits in an exterior wall on Type I to IV construction, the assembly generally also needs to be tested to NFPA 285. Which applies depends on the wall construction and use, and the design professional and the AHJ determine it, not the foam type.
Why project teams choose Insulation Company
On many projects this work is scoped alongside commercial air sealing and metal building insulation, and one written estimate can cover both.
- The commercial and industrial division of Polar Insulation, headquartered in Wewahitchka, FL
- New construction and retrofit work, for contractors, developers, owners, and facility teams
- A written estimate before any work is scheduled
- Proposals include a W-9, state contractor licensing details, and a certificate of insurance
From estimate to installation
Send drawings or photos and the building address. The price is built from open-cell or closed-cell, thickness required, and substrate condition and prep. The written estimate names the system, the coverage area, the R-value target, any removal, and the schedule.
- Review the assembly and goals. We look at the drawings or the existing wall and roof construction, the moisture exposure, and whether the job needs air sealing, added R-value, or both.
- Select open-cell or closed-cell. Based on the assembly, moisture exposure, and available cavity depth, we specify which foam type fits, since the two are not interchangeable on performance or cost.
- Prepare and mask the area. Adjacent surfaces, equipment, and finishes get covered, and the substrate is checked for cleanliness and dryness before any foam is applied.
- Apply foam to specified thickness. Foam is sprayed in passes to reach the target thickness called for by the assembly and the performance goal.
- Ventilate through the re-entry period. The area stays ventilated and closed to other trades and occupants for the period the foam manufacturer states before normal access resumes.
Questions from facility and project teams
Should I use spray foam or a different insulation system?+
Foam earns its cost when a job needs air sealing and insulation together, or when the cavity is irregular and hard to fill with batts or boards. A standard framed wall with easy access and no moisture problem often does not need foam at all.
Can spray foam go over a wet or leaking surface?+
No. Foam has to bond to a substrate that is clean and dry, and spraying over a wet or leaking surface traps the moisture rather than solving it. The leak or moisture source gets fixed first, then the substrate is checked before spraying.
What do you need to price a commercial spray foam insulation project?+
Drawings or photos, the building address, and the areas involved. The estimate turns on open-cell or closed-cell, thickness required, and substrate condition and prep.
