A soft, expanding foam that fills every nook, seals air leaks and dampens sound in walls, ceilings and attic roofs.
Open-cell foam is lighter and softer than closed-cell and expands to many times its liquid volume. That expansion carries it into the corners and seams that batts leave behind, creating an air seal as it insulates.
It also has an open structure that absorbs sound, so it is a good fit for walls between a media room and a bedroom or ceilings under a busy floor. We use it for interior walls, vaulted ceilings and unvented attic roof decks where its vapor-open nature suits the assembly.
Open-cell foam flows around framing, wiring and plumbing. It is a strong choice in oddly shaped cavities and in older framing that is not perfectly straight.
The open structure absorbs sound better than most materials. Walls and ceilings sprayed with it tend to be noticeably quieter.
Open-cell foam lets some moisture vapor pass. That helps assemblies dry, but it is not a good choice for crawl spaces or below-grade walls where closed-cell is better.
Open-cell foam overfills the cavity, so we trim it flush for drywall. Clean trimming keeps the wall flat and keeps the finished surface looking right.

We walk the attic, walls, crawl space and equipment, measure depths and use thermal imaging when it helps.
We protect the house, seal air leaks, place baffles and fix small problems so the insulation can do its job.
Loose-fill, batts, foam or board goes in to the planned depth, with clean edges and clear markers.
We measure the result, take photos and test air leakage when the scope includes it.
We walk the finished work with you, answer questions and leave the site clean.
It helps considerably, particularly against airborne noise. For heavy impact noise, extra layers may be needed.
It uses less material per volume, but it also has a lower R-value per inch. The right choice depends on the space.
Closed-cell is the better choice there, because it resists moisture. We explain the reasoning during the visit.
Open-cell foam can take on moisture if it gets wet, so it belongs in dry assemblies protected from leaks.
The foam cures quickly, and we give you the manufacturer re-entry time before we begin.
