Why Wall Insulation Matters
Many Massachusetts homes have uninsulated or under-insulated walls, leading to cold drafts, uneven temperatures, and higher heating costs. Dense-pack insulation fills wall cavities completely for year-round comfort.
The Dense-Pack Method
- Small access holes drilled from exterior or interior (typically 2.5-3 inches)
- Cellulose or fiberglass blown at high density to eliminate settling
- Complete cavity fill verified through density testing
- Professional patching and finish work
This proven technique works in existing homes without major renovation disruption.
Material Options
- Dense-Pack Cellulose - Made from recycled paper; excellent air-sealing properties
- Dense-Pack Fiberglass - Non-combustible; good for specific applications
Material selection depends on wall construction, moisture conditions, and program requirements.
Installation Process
- Site preparation and protection of work areas
- Strategic hole placement (typically every 16" on center)
- Dense-pack installation with density verification
- Hole patching with matching materials
- Cleanup and final walkthrough

- High heating bills despite adequate attic insulation
- Planning exterior siding or interior renovation work
