The Cottage is coming along well. Walls up, plywood on. Trusses are coming soon and the walls on the Main House will be starting tomorrow. We are doing the exterior walls as two, separate 2×4 walls with a 1″ gap between. This gives us an 8″ wall and about an R-37 insulation level.
R-values (“resistance”) are something that measures how well the house retains heat or cool inside. The higher the value, the better. Code is R-21, so we are about 60% better. This will give our tenants much lower utility costs. Our attic will have close to two feet of insulation. The floors will also have a foot of insulation.
And we are doing the same construction on the Main House.
Both houses will have a mini-split heat pump unit that will heat and cool at an incredibly high efficiency level. So combined with the added insulation, electric bills for both houses should be very low.
Well, it’s getting late. More later.
