Icynene spray foam was installed Monday at our AAC block project . It took about 5 hours to do the roof deck and gable ends. This is a sealed attic, eliminating the need to insulate at the ceiling joists. Even the upper chord of the roof trusses were covered, minimizing heat transference through the wood. The attic will not go through temperature extremes, subsequently giving added life to the HVAC equipment. Everything was sealed perfectly.
We gave the house an airing for the next two days. It needed it on account of the outgassing from the spray foam insulation. The weather was dry and we vented it well. The drywall delivery came Wednesday afternoon. The next morning a crew of drywall hangers arrived and by 5:30 p.m. everything was up. We put in special ½” thick ceiling boards, manufactured to span the 24” centers of the joists. The crew did a great job!
Another crew came in Friday morning to cleanup and start the taping/ mud. We aren't doing any steel outside corners. It’s all bullnose returns at the doors and windows. repairing sliding glass doors is not as simple as it looks, we had to secure it with some nails, but mainly a strong adhesive especially manufactured for the plastic bullnoses. This costs a little more than the typical steel 90 degree corners, but there will be considerable savings because the doors and windows will not be cased in wood trim. This produces the feel of a southwestern home. Initially we thought about applying plaster to the AAC block walls, but decided to stay with drywall because of costs. We went through 20 large tubes of adhesive applied to the back of the boards that were hung on the block walls. Since AAC block is lightweight, it can receive the drywall screw. That combined with securing at the top & bottom plates, the door and window bucks (2x8 pressure-treated lumber), and the adhesive, we found that all the drywall was successfully adhered the next day.Finishing the drywall will take about 4 days. We’ve been protecting the floor with sheet plastic. During the past week the well was installed. We’re getting 16 gal/min and we only went down 260’. On Friday, we trenched the house to put in the water line and pump wiring. Soon, we will be trimming out the porch posts & ceilings, then moving on to stucco! In the interior we’re starting the cabinetry and tile! For more pictures of this project click here! To read more about this project click here!

Synergy Building Co. began to clear a house site in December 2008 and poured the footing during Christmas week.
This is an 1800 sq.ft. 3-bedroom, 2-bath solar-oriented, energy efficient house built with AAC block (Autoclaved Aerated Concrete). This 8” thick lightweight solid block has a high insulation value and is fireproof and is an affordable alternative to wood framing.
In addition to a radiant heat slab-on-grade, the house will have wide overhangs to minimize heat gain in summer and a sealed attic with Icynene spray foam on the roof deck. We are looking forward to putting on a stucco exterior finish and give the one-story interior spaces a southwestern feel with bullnose returns to all windows and doors. We even plan to eliminate baseboard, as well as casings, and put an exquisite stained finish on the slab floor. Interior doors are 3’ wide for handicap access. The master bath has a curbless shower and a soaking tub for de-stressing and relaxing. A wood-burning zero-clearance fireplace supplements the radiant heated floor and heat pump. The 1.8 acre lot is 5 miles out of town with plenty of quiet. The 9’-4” ceilings and open kitchen-living-dining allow for a spacious feeling with lots of south-facing light.
Plenty of rain this winter and spring has meant construction is taking 6 months vs. the 4.5 months we originally thought. There were snow flurries at the time we started laying the AAC block. But the lot has been cleaned up, we just drilled 260’ to put in the well and are getting 12 gallons/minute, and we’re leafed out in the past month and looking forward to putting in a water element in the front of the house. Most of the landscaping will have to wait for Fall however. We’re going to avoid putting in a lawn by doing ground cover and water-resistant plantings, mulch, and some hardscapes. We've decided to hire someone from https://ziehlerlawncare.com to help with the landscaping.
Coming up next week is the spray foam and drywall.
