Rough framing is almost complete

Now that the rough framing is nearly complete, we will be moving on to some new GBI decisions. We are currently getting quotes for sealing the attic, just as we sealed the crawlspace. This has all the same benefits of sealing the crawlspace, but it has additional benefits. First, you no longer need attic vents or fans. Another benefit has to do with removing a limitation normally imposed by building green. Green building frowns on the use of "can" lights (also called recessed lighting) because it creates a gap from the attic into your conditioned space. If your attic was not sealed, you would be creating a bridge from outside air to your inside conditioned air. Thus, if you seal your attic, you no longer need to worry about that, and you can utilize recessed lighting without harm to your home's energy efficiency.

First Floor Framing

The first photo shows the framing from the front of the house and the second photo is from the back. Notice that the first signs of a roof line are seen in the photo of the back of the house; that is the vaulted master bedroom.

Catching Up: First Floor Joists

The first floor's joists are laid. Recent code changes require that the inspection be done before the subfloor is laid, giving us the opportunity to take these photos. This type of joisting is becoming more widely used due to its superior strength and durability. Since it uses less wood than traditional floor framing, it is a GBI choice for resource efficiency.

Catching Up: The Crawlspace Is Sealed

Here you can see the crawlspace sealing that we discussed before. Notice that even the footings are wrapped. Around the outside perimeter a dense foam sheeting is laid and sealed with a foam "caulking".

Catching Up: Gravel In The Crawlspace

Pea gravel is laid down inside the crawlspace for additional drainage and to provide a level crawlspace floor.
