What our commercial air sealing work includes
- Window, door, and louver rough openings. Gaps between the frame and the rough opening are a direct path for air to move if not sealed after the unit is set in place.
- Roof-to-wall and wall-to-floor transitions. These are places where two different air-barrier materials or trades meet, and continuity depends on how well that transition is detailed and sealed on site.
- Penetrations for pipes, conduit, and ductwork. Each penetration through the envelope is a potential gap unless it is sealed individually with a material suited to that specific penetration type and size.
- Rim joists and structural transitions. These narrow, often overlooked assemblies combine framing, sheathing, and multiple materials meeting at once, making them a common and easily missed leakage point.
Buildings we install it in
We install it in office buildings, warehouses and distribution centers, and medical buildings, along with other commercial and industrial property.
Projects we scope differently
- A building with an actual roof or wall leak letting water in needs that repaired first; air sealing addresses air movement, not an active water intrusion problem.
- A room with an echo or noise problem coming from within the room itself, not air leaking between spaces, needs absorptive acoustic treatment rather than air sealing.
- Sealing gaps in process equipment, ductwork insulation jacketing, or mechanical systems for energy reasons is mechanical work, separate from the building-envelope air sealing covered on this page.
New construction and retrofit coordination
On new construction, air sealing happens in step with framing and rough mechanical and electrical work, sealing penetrations, rough openings, and transitions as each one is created rather than going back over the whole envelope at the end. We coordinate timing with framing, window, and MEP trades so a sealed penetration is not opened again by a later trade, and the air barrier stays continuous through to close-in and any required testing.
In an existing building, we identify leakage paths from a visual inspection, past comfort complaints, or a blower-door or thermal-imaging test if one has been done, then seal the specific penetrations, transitions, and rough openings found. Work is scheduled around occupied hours, and areas are accessed with minimal disturbance to finishes already in place, sometimes reaching penetrations from above a ceiling or behind an access panel rather than opening a whole wall.
Access, phasing, and safety on site
- Access. Many of the gaps worth sealing sit above ceilings, behind equipment, or inside wall cavities, so reaching them sometimes means removing a ceiling tile, panel, or piece of trim and putting it back.
- Scheduling. On new construction, sealing has to happen at the moment a penetration or transition is created and before the next trade covers it; missing that window means opening the area back up.
- Phasing. In an occupied building, sealing is done space by space so finishes, equipment, and activity in adjacent areas are not disturbed while one zone is under way.
Why project teams choose Insulation Company
- 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, the applicable state contractor licensing details for the project's jurisdiction, and a certificate of insurance
How the estimate is built
The price is built from number and type of penetrations, envelope size and complexity, and new construction timing vs retrofit access. The written estimate names the system, the coverage area, the R-value target, any removal, and the schedule.

Questions from facility and project teams
Is air sealing required by code?+
Commercial energy codes generally include a continuous air-barrier requirement met through a material, assembly, or whole-building testing path. Whether a specific building meets that requirement is a determination made by the design professional and the authority having jurisdiction.
Can air sealing be tested?+
Yes, though the testing itself, blower-door or whole-building testing, is typically arranged through the design or commissioning team rather than performed as part of the sealing work. We seal to the identified paths and locations found.
