Wow! We started demolition last Thursday. And this shot was taken from our roof this morning. It feels good, to be so far in so little time. Now we are turning our attention to the inside framing. Next week we will begin rough in for electrical, mechanical, and plumbing. I'm hoping to call for my inspection by Friday so that I can begin drywalling next weekend.Today it was Nate, Jeff, and I again. We worked on filling in some of the loose wood trim and framing details. The house is really starting to look (and feel) great. We're getting a lot of positive comments from the neighbors, which helps us feel that much better about our decision to stay and add-on.
I've been getting a lot of questions about what I'm using for insulation. The walls and roof panels are all SIP's (Structural Insulated Panels). They are made with 1/2" OSB (stronger than typical OSB) and injected with an ozone-friendly poly-stryrene foam. Our walls and roof are 6" thick and have an R-value of 42. Most homes today are built with an R-value of 19 and roof R-value of 38. This means that both our walls and roof are super insulated! They feel great right now, and Kathy commented the other morning how much quieter the downstairs was with the roof up in place. SIPs are just a very efficient and effective way to build a home, even a custom home like our addition.
Not much more to add. I'll take some shots after we have the walls framed in, but it's going to be pretty boring until we drywall and start adding the finishes. Have a fantastic weekend and be thinking of the Zimmer Crew!Ciao!

WOW! That is sooo impressive! I didn't see the Zimmer household pre-construction, (I am sure there are plenty of before shots)I definatley want to check it out when you are done...or, when I come over to help paint...
Hi, Aaron. The insulation is injected polyurethane foam, with R-7 per inch of thickness. Polystyrene (a white, Styrofoam-type insulation) only has an R-value of 3.5 per inch. We don't use it for this and other reasons. Having said that, any type of SIPs is better than insulating with fiberglass or cellulose, because SIPs have closed-cells that do not allow air or water vapor to go through or get into the walls.
