It was a great spring day in the Twin Cities, so our family took a little outing to the house to verify all the rough-ins and finalize blocking locations. Our friends, the Kosirs stopped in for a tour as well.
The house is now all wrapped in a futuristic-looking silvery Tyveck thermawrap. This drainwrap protects the sheathing from water penetration but is vapor permeable so it allows water vapor from the inside of the house escape. This is a good thing. We don't want mold growing behind out wallboard or exterior siding. It also acts as an extra thermal barrier. We've combined with the "dri-side" clip system so that there is an air space between the back of our siding and the membrane - allowing for better venting and slightly better thermal performance - giving us an extra R2 value on the exterior wall. Combined with the spray foam insulation - we'll have R30 walls and an R50 roof system. The window installation is complete. The sunshades (to be installed just above the windows on the front/south side) are fabricated and ready to be sealed and installed next week. Metal siding should start going up next week also.
