Update 5_31_11 Great progress made on the house. There are a few items I wanted to share regarding energy efficiency. The windows are DP 50 ( DP =design pressure) and are low E Argon (argon is a inert gas), south central energy star compliant. the manufacturer is Ply Gem, Mira aluminum clad premium series. If you remember the Green Building post I had written (see Blog dated 5_18-11), low E windows in combination with radiant barrier sheathing have the most impact on economical, energy efficient building. The picture looking up into the roof trusses shows the radiant barrier sheathing. This particular product is LP Tech Shield. It blocks heat in the roof sheathing from entering the attic enclosure. It boasts lowering the attic temperature 30 degrees F in the summer, which equates to about a 17% cut in air conditioning bills. It also reduces heat load on the air handling system located in the attic space. Between any gaps or cavities, a polyurethane yellow foam is being used called Great Stuff. The advantage of the polyurethane foam over a latex foam is absorption of water versus the sealing effect of the Great Stuff. Look at the storage space behind the bonus room. This picture does not really do the house justice. Leading from the bonus room door, the space runs over 3/4 of the way towards the rear of the house. The “knock” on the use of roof trusses has always been storage space. This house proves that, if provided for in the trusses design process, there is plenty of space to be gained. Dramatic inside looks from the entry window and the tower windows adds to the spaceousness of this house’s design.
5_5_11 Update: Trusses being set today make the house take a dramatic visual change. There is a bonus room over the garage area, but the striking feature of this house is the openess and expanse of the great room, dining room and kitchen areas. The bottom chord of the truss slopes up from the inside of the 2×6 walls to form a cambered ceiling, which rises over 4′-0″ at an 8/12 pitch, goes flat, then returns to the standard plate height at the bedroom walls. There is a open boxed storage area as well, leading from the bonus room to the rear of the house. The steep pitches add to the towering effect of the roof system, while blending the differing plate heights together.
Update 5_2_11 Went by the job to discuss delivery of the roof trusses tomorrow and couldn’t help but take some photos of the recently set tower panels. These 14′-0″ tall panels give the house a medieval effect. The arches built into the panels are specifically planned to house the windows order to fill the rough opening. This is another example of predictable results. Predictable results relieve the burden of worries from the framer / general contractor. The continuous load path from the roof above is compensated in the wall panel carrying it. There is no need to go back to install stud clusters underneath girder trusses because the panels have been constructed with the level above it in mind.
Great looking house package arrived to Sunset Beach, North Carolina. The Thistle is an upscale premier location to showcase wall panels and component construction. This is actually the second panel house in this location. Lot 62 is located behind the beautifully crafted clubhouse and is the only house under construction at the present time. To be first is to be noticed is what I always say, but then who listens to me anyway. Small crew erecting, but it doesn’t distract from the ratio of man hours against what gets accomplished. Indeed quite a feat to have two people (the day I was there) make as much progress as what is illustrated in these photos. Ten foot walls is the standard, the right front which was not yet set is a fourteen foot “tower”. Massive open area in the dining, kitchen and great room gives this plan an expansive feel. Double sole plates used in NC, bottom being treated. The interior walls were compensated for by being 1 1/2″ shorter and just having the single treated plate. the 2×6 exterior walls came unsheated per contractor request.
