R-value tells you resistance to heat flow, but installation quality, gaps, compression, and wind washing can slash real performance. Think carefully about assemblies, not just products, and comment with your target R-values for feedback.
Materials That Matter: From Cellulose to Cork
Cellulose, made from recycled paper and treated for fire resistance, excels at filling irregular cavities and stopping air movement within walls. Its hygroscopic nature aids moisture buffering. Considering cellulose? Post your questions about settling and densities.
Beating Thermal Bridges with Continuous Insulation
Foam, mineral wool, or cork boards over sheathing cut thermal bridging and protect against wind washing. Add a ventilated rain screen to dry cladding and extend durability. Ask about thickness targets for your climate zone.
Vapor Control Layers that Actually Work
Use smart vapor retarders that open in summer and close in winter, paired with airtight layers. Locate them by climate and assembly type to avoid unintended traps. Ask for our schematic guide tailored to your region.
Ventilation Partners: ERVs, HRVs, and Balanced Air
Tight, well-insulated homes need fresh air by design. Energy recovery ventilators balance humidity and minimize heat loss, improving comfort and indoor air quality. Share your ERV settings and we will crowdsource ideal configurations.
Case Note: Basement Comfort Without Mold
A damp basement received rigid foam against the foundation, taped seams, and a continuous capillary break beneath new plates. The space warmed, odors faded, and dehumidifier run-time dropped. Post your basement square footage for targeted tips.
Retrofit Roadmap for Existing Homes
Start with a Blower Door and Infrared Scan
Testing finds the leaks you cannot see. Infrared cameras reveal missing insulation, voids, and thermal bridges. Set a target air change rate, then retest. Comment with your ACH readings to benchmark against similar homes.
Attic Air-Seal, Then Insulate
Seal top plates, chases, and penetrations before adding blown cellulose or fiberglass. Install baffles for ventilation and protect can lights appropriately. Share attic photos and we will help spot common bypasses you might miss.
Walls and Floors: Dense-Pack, Flash-and-Fill Strategies
Dense-pack walls through small holes, or use flash-and-fill with thin spray foam plus cellulose. For floors over crawlspaces, air-seal and insulate the perimeter. Ask about safe drilling patterns and patching methods for neat finishes.
Prioritize high attic R-values, airtightness, and enough exterior insulation to keep sheathing above dew point. Triple-pane windows and robust air barriers finish the package. Share your zone and target sheathing temperatures for guidance.
