Rough framing has been inspected by the city for code compliance and the HERS (Home Energy Rating System) inspector for a tight building envelope. Which means plugging all gaps in the framing so there are no easy paths for air to transfer from the interior to exterior.

The insulation is brown instead of pink because the binder is made from renewable resources instead of petroleum based products. The binder is combined with sand and recycles glass to make the insulation. This results in 70% less energy used to make it and it doesn't contain toxins like phenol,formaldehyde, or acrylics.



R-21 is installed in the walls. 'R' is a measure of thermal resistance so basically the higher the R value the better your insulation is and more energy efficient your home is. The current code is for R-13 but we used six inch framing on the exterior of the building so that we have a deeper cavity for better insulation. Over the life of the building this is a far more significant than something like bamboo floors or other claims at being 'green'.
