The Katywil Essential House, 1350 sf
Life at Katywil: The houses outside
Designed to be very low maintenance, Katywil houses are cloaked in HardiPlank, made from cementitious fibers, which are pre-painted at the factory, have a 15-year paint warranty, a 50-year performance warranty, are non-combustible, resist rodents, mold, cracking, and, best of all, are environmentally friendly.
The walls themselves are a foot thick, filled with dense-pack, blown-in cellulose, and rated R-45. The roof is also cellulose-insulated with an R-value of 65. Windows are low-e, argon-filled, and triple-glazed to provide maximum passive-solar access and cross-ventilation.
Note the large south-facing, passive solar windows looking across to Stone Mountain and southeast to Catamount.
