Description
Add more R-value to your exterior wall with this additional 3/4″ rigid foam insulation! The standard GHC home comes with R-19 exterior wall insulation, but if you add this option you’re looking at around R-21. That equates to more than a 10% increase in heat retention for your home!
If this option is ordered, the house will overhang a standard foundation by 3/4″. Should you want your home flush with your foundation, be sure to adjust your plans by 1.5″ on both the width and length of your plan.
