#712: What Clients Want, Heat During Construction, and Enclosure Retrofit Sanity Check

Salvaged materials, like old shingles, can be effectively reused to maintain aesthetic continuity and save costs on renovation projects, especially when blending new work with existing structures.

Be prepared for hidden issues in older homes; destructive investigations are crucial for understanding existing wall assembly performance and informing retrofit decisions.

Educate clients on the long-term value of building quality (durability, health, efficiency) over cosmetic finishes to foster better investment in the building envelope.

When heating a house under construction, prioritize methods that do not introduce excess moisture (like torpedo heaters) or harmful fumes; consider electric furnaces, ducted heat pumps, or indirect gas-fired heaters placed outside.

Monitor construction moisture carefully; consider running dehumidifiers even in winter, as the heat generated can contribute to warming a well-sealed building while removing humidity.

For exterior retrofits, ensure adequate exterior insulation for your climate zone (e.g., R-10 or R-12 for 2x6 walls in climate zone 6A) to prevent cavity condensation. Layering foam insulation with offset seams can minimize shrinkage issues.

When moving insulation to roof rafters to create a conditioned attic, ensure air and thermal boundaries align, and consider the type of insulation and roof assembly for proper air sealing and moisture control. If venting is planned, ensure it doesn't compromise the insulation's effectiveness.
