Drill and fill insulation involves drilling small access holes into exterior or interior walls and injecting high-performance blown-in insulation into enclosed cavities. The result is a fully insulated wall system without removing drywall or exterior cladding.
This method is ideal for older homes in Peterborough where walls are often under-insulated or have settled insulation over time.
Common applications in Peterborough include:
- Older homes with empty wall cavities
- Retrofit energy efficiency upgrades
- Exterior wall insulation improvements
