In this package, we are specifically making sure to build your project environmentally friendly as well as maximize energy conservation in the finished product. Although we are resource-efficient in all of our packages, this package allows for increased attention towards sustainability. Normally, code enforces an R-value of 24. When we build a house from our environmental package that has an R-value of 40 or higher, it takes less energy to exist as a whole. This package will bring your heating and cooling costs lower.
