Cavity filling
Open-cell spray foam expands around corners and framing throughout deep insulation bays.

Open-Cell Spray Foam
Choose light, expanding open-cell spray foam insulation to fill deep cavities in above-grade interior assemblies.
The application
Designed around
your building.
Open-cell spray foam insulation expands significantly during installation, filling wall and roof cavities around irregular details. This spray foam is commonly considered for above-grade insulation where sufficient cavity depth is available. Because open-cell insulation remains vapour permeable, its location and vapour-control strategy must fit the building design. We confirm those details before recommending this spray foam insulation for a Belleville project.
Why it works
Performance starts
with continuous coverage.
Sound absorption
The softer spray foam structure can help insulation assemblies reduce sound transfer.
Efficient coverage
Open-cell insulation suits larger above-grade areas where spray foam has adequate depth.
