When Interior Insulation Is Used

Interior insulation is an option when walls can't be accessed for cavity insulation, when adding to existing cavity insulation, or when renovating with new interior finishes. It reduces floor space slightly but can significantly improve comfort.

It's also used in basements and conditioned crawl spaces where interior insulation is part of the assembly. We assess your walls and recommend the best approach.

Materials and Assembly

Rigid foam, mineral wool, and other products can be applied to the interior. A vapor barrier or vapor retarder may be needed depending on climate. Drywall or other finish is applied over the insulation.

We ensure proper vapor control to prevent condensation within the assembly. We follow building science principles for durable performance.

Installation Process

We prepare the wall surface and install the insulation layer. We seal seams and penetrations. We coordinate with drywall or finish contractors if needed.

Interior insulation reduces room dimensions slightly. We discuss the trade-offs and ensure the assembly is correct for your climate.
