Air sealing before insulation
Air leaks can make insulation underperform. Before adding insulation, many Reno homes benefit from sealing gaps around attic penetrations, can lights, plumbing chases, duct openings, attic hatches, rim joists, and crawl space penetrations.
Air sealing helps reduce drafts, improve comfort, protect conditioned air, and make new insulation more effective.
Common air leak areas
- Attic hatches, can lights, fans, and top plates
- Rim joists, crawl spaces, and floor penetrations
- Duct chases, plumbing openings, and garage gaps
- Rooms that feel drafty even after heating or cooling
