Performance per inch
Closed-cell spray foam provides effective insulation where installation depth is limited.
Spray Foam
Dense coverage for demanding assemblies
Closed-Cell Spray Foam
Choose dense closed-cell spray foam insulation for compact assemblies that need strong air and vapour control.
The application
Designed around
your building.
Closed-cell spray foam insulation delivers high thermal resistance in a compact depth and cures to a firm surface. This spray foam is often selected for foundations, rim joists, metal buildings, and compact roof assemblies. Where lower vapour permeance is part of the design, closed-cell insulation can combine thermal, air, and vapour control. We verify that the substrate and assembly suit this spray foam before insulation begins.
Why it works
Performance starts
with continuous coverage.
Firm finish
This spray foam insulation cures into a rigid layer on properly prepared substrates.
Air and vapour control
Closed-cell insulation supports assemblies requiring spray foam air sealing and lower vapour permeance.
