Dense packing places loose-fill insulation into suitable enclosed cavities through access openings. It can be an option when exterior walls are already finished and removing the entire wall surface is impractical.
Cavity condition, existing material, wiring and siding or interior finishes influence whether this approach is suitable. Access holes and finish repairs may be required. Ask CJM to include the access method and responsibility for patching in the scope, rather than assuming the work leaves every surface untouched.
What to discuss with CJM
- Review wall construction and existing insulation.
- Agree on access locations, material and finish repair responsibilities.
- Fill suitable cavities and inspect the agreed work areas.
Questions about exterior wall dense packing
What is dense-pack insulation?
Loose-fill material is installed into enclosed cavities at the density specified for that product and application. It differs from loose material spread across an open attic.
Will you need holes in my walls?
Installation needs access to the cavities. The location and repair method depend on the wall and should be explained before work begins.
