Good Building Score: 39

Moderate R-value meets moderate thermal capacity for a low cost insulation capable of high performance, comfort and low carbon. Proper installation is an art as much as a science and takes skill and experience.

Moisture risk and potential settling are the major downsides. Us a Vapor Variable Membrane on the interior to mitigate moisture risk. Ensure 3.5-4lbs/ft3 (feels like a firm mattress) to mitigate settling.

Whenever possible we are switching to Blown-In Woodfiber Insulation for more of the good with reduced risks.
