The insulation and air barrier for the home’s thermal envelope were some of the most important remodeling decisions we had to make. We had to weigh performance, cost and availability, energy efficiency and recycled content. The documentation shows that the roof R-value is R-58 and the framed walls are R-32.
Our thermal envelope design and documentation:
Dibble-Twinsprings Thermal Envelope Design
Early Dibble-Twinsprings Insulation Documentation
Updated Dibble-Twinsprings Insulation Documentation
These were the resources we used.
