2/11/15 - Structural Insulated Panels (SIPs) are large and unwieldy. They have to be lifted into place with a crane. However, one of the many really nice features of SIPs is that after they arrive, they can be tipped up in place, secured, and Voila! There are walls! They have a finished flat surface on the exterior and the interior that is plumb. They are flatter, straighter, and consume far less wood fiber than conventional framing. (I had a little help with that one!) The insulation is already in the walls along with the raceways for the electrical wiring. The door and window openings are already in place. Thus, a future resident can look out her bedroom window (opening) for the first time. It’s pretty exciting!
