How Heat Moves Through Your Home
Conduction, Convection, and Radiation in Plain Terms
Conduction is heat slipping through solid materials, convection is heat hitching a ride on moving air, and radiation is heat traveling as waves. Effective insulation resists conduction, air sealing reduces convection, and reflective layers curb radiant gains or losses.
Why the Building Envelope Matters
Your building envelope is the protective shell of walls, roof, floors, windows, and doors. When properly insulated and air sealed, it slows heat transfer, reduces drafts, and stabilizes indoor temperatures. Tell us where your home feels drafty, and we’ll help prioritize fixes.
A Quick Story: The Attic That Changed a Winter
One reader sealed attic leaks, added baffles, and topped up blown-in cellulose to the recommended R-value. Their furnace cycled less, upstairs stayed quiet, and winter bills dropped sharply. Share your attic success—or frustration—and inspire someone planning their weekend project.
Choosing Insulation Materials with Confidence
Fiberglass, Cellulose, or Mineral Wool?
Fiberglass batts are accessible and familiar, cellulose packs dense coverage and recycled content, while mineral wool offers fire resistance and sound control. Consider R-value per inch, moisture tolerance, and installation method. Comment with your climate and we’ll suggest a smart match.
Spray Foam Smarts: Open-Cell vs Closed-Cell
Open-cell foam excels at air sealing and sound dampening, while closed-cell adds higher R-value per inch and moisture resistance. Use open-cell in interior cavities, closed-cell for rim joists or exterior sheathing. Always prioritize safe installation and proper ventilation during curing.
Attics, Walls, and Floors: Priorities That Pay Back
Before adding insulation, seal gaps around light fixtures, top plates, and hatches. Install baffles for ventilation, then reach code-recommended R-values. This reduces stack-effect heat loss dramatically. Tell us your attic height and access, and we’ll propose a practical plan.
Attics, Walls, and Floors: Priorities That Pay Back
Thermal bridging happens when studs carry heat through walls. Add continuous exterior insulation, use advanced framing, or dense-pack cellulose to minimize gaps. Combine with a smart air barrier and housewrap for durability and comfort in every season.
Vapor Control by Climate Zone
Cold climates often need interior vapor retarders, while warm-humid regions benefit from exterior drying pathways. Choose materials that allow safe drying in at least one direction. Ask about your zone, and we’ll suggest layer orders that protect structure and comfort.
Fresh Air Without Losing Heat
Balanced ventilation with an HRV or ERV supplies filtered air while recovering heat or cooling energy. Pair tight insulation with controlled ventilation to avoid stuffiness. Curious which unit suits your home’s size and climate? Post details and we’ll recommend options.
Mold Prevention Wins
A homeowner sealed a damp crawlspace, added rigid foam to walls, and installed a dehumidifier. Musty odors vanished, insulation stayed dry, and energy use stabilized. Share your moisture mystery, and we’ll help identify sources before you insulate over the problem.
Air Sealing: The Invisible Upgrade
Where Homes Leak Most
Common culprits include recessed lights, attic hatches, plumbing and wire penetrations, fireplace surrounds, and rim joists. Use caulk, gaskets, and foam appropriately. Tell us your home’s era and we’ll highlight typical leak points to check this weekend.
