Building in NW GA soon, I'm researching SIP build vs stick, it looks like the way to go. I see them in osb and metal, not sure which is better or cost less. This is a vacation home not full time, it will be on a slab. How are the panels connected to the slab, do make cut outs for the anchors? If I get local carpenters to do the panel install perhaps not having experience would I really save money over having the SIP manufacturer use their crew. I see these crew do it in day. Also there are issues with mountain roads to get a semi in but that's another issue. The build has perfect southern exposure for passive solar and views. Any known SIP manufactures within a reasonable distance? So far I found SIPS team in Ga, there must be more. What is you guess to build a 24X32 1 1/2 story shell. I have the slab cost done. tks

gosolar3, of course you have to weigh some options and make an informed decision. I would urge you to look into steel skins because they have a number of advantages when compared to OSB skins. Steel SIPs do not rot, nor do they promote mold growth or flame spread. Termites cannot damage steel, and the foam is typically borate treated. Steel SIP spans are greater, but they weigh less than OSB so you don't need that crane. This is important especially to you if you have limited access at your site.

Typically steel SIPs slide into a metal track (U-channel) which has been connected to the slab with wedge anchors. The panels are then screwed on both sides of the track.

You're right, an experienced crew can get the shell erected really fast. On the other hand, someone with basic skills can do a good job with them, too. I guess this choice comes down to time; you'll have to pencil out the numbers when you get some detailed bids. But in Georgia you're right in the middle of the steel SIP industry.

gosolar3, as I’ve never worked with steel SIP’s, I really can’t make a comment on them. I would think they would be more expensive than OSB/ EPS panels and harder to work with. AnOSB/ ESP panel can be easily modified on site. The cost of the panels will be determined by the cost of the panels plus shipping. If termites are a concern, the OSB panels can be treated. To connect OSB panels to the concrete, a capillary break must be put down first on the concrete. Pressure treated plywood works well for this. This keeps the OSB from contacting the concrete. Untreated wood that comes into contact with concrete will rot. Slice the plywood into strips an inch wider than your bottom plate that the SIP panel will fit over. This will keep the OSB from direct contact with the cement. Glue and bolt the pressure treated plywood and bottom plate to the concrete. Now you’re ready to place the OSB panel on the bottom plate. I usually train the general contractor’s crew on the proper assembly techniques on site. Then I have a trained crew in that area.

They were about .50 a sq less But I don't think I like them they are only avail in 4' widths. I'm getting a price of $4.25 for 4 1/2" sound right?

gosolar3, $4.25 sounds about right. I might suggest going to a 6-1/2" wall and a 8" roof panel. I imagine that your main concern is keeping your house cool in the summer heat. The thicker roof panels will help to keep the summer sun's heat from coming through he roof (and your air conditioning costs from going through the roof). It's not that much more expensive and I think it will be well worth the cost.

Good point, but I think I need one on site for the ridge beam which will be 24' long up a 1 1/2 story peak. Can't see how that can get muscled up that height. Chris when is a good time to call you, I see you sell panels.

Scissor lift for ridge beam. Box beams can even be built in place; in that case you would just need 2 guys with ladders.

For Steel sips, I want to cover the outside with cedar lap siding, how do you attach it to the metal skin?

Maybe a drawback, perhaps sheet metal screws. Steve may have a solution

RossG3, all claddings walls or roof are by screw attachment for cedar lap siding I would recomend a sharp point wafer head screw directly to skin
