Nut, I was going to do 10s, but with the scissor trusses and 1' of concrete wall height, I think it will be enough. The Trusses are 7:12 outside slope, with an inside slope of 4:12. I'd like to keep the overall enormity of the building down.

Read, Radiant slab...

Wiz, We built our last house out of SIPs about 9 years ago. It was not easy. Everything was more money, including the crane that drove up to VT from MA... Uhhhh. It was an awesome house though. Three floors of radiant. Very comfortable. I'd do it again now that I struggled through the first go...

Kaizen... You can get them from a lot of places these days. If you go to Huber's website (below) you will find dealers on one of the links. I asked my lumberyard and they said "no", then I asked "are you sure", then they said "oh, I guess we do". You can get them in 1" R3.3, or 1 1/2" R6.6. They...

Not sure what you saying readhead, but Roxul is ~R15 (2x4), plus the R6.6 sheathing is ~R22. And I get no thermal bridging. I'm happy with that combo. This is for a garage. Is that what everybody's here for?

mt... These panels prevent you from having to wrap the building after it's sheathed. Gets pretty cold in Maine. I'll definitely fill the cavities as well. This thermal break prevents intrusion through the stud walls. It's just an another layer of protection.

Yeah... The sheets are not cheap, but the labor saved (personal sweat) will be worth it. With taped seams, I'm sure I could just use the pink junk in the walls, but won't. I'll go with rock wool, possibly dense pack. Feels a little strange going with 2x4 walls, but it makes sense. I'll go with...

Today I decided to go with 2x4 walls with the Zip wall insulated sheathing. I can get the sheets locally at 1-1/2" for R6.6. That's a pretty crazy total thermal barrier when taped on the outside. There will be no wood transfer of cold indoors. The panels are a little more than going with regular...

I called the seller earlier today and it turns out he does not have the paperwork which supposedly came with the trusses. I said "really, you lost the engineering paperwork?" "Yeah, must of tossed it along the way". I had to back out of that. The good news is that I tried a new lumberyard and...

Thanks DLC. Appreciate that. Great forum.

I appreciate everybody's input. All good stuff. I will: -Discuss transportation concerns with seller -Call truss manufacturer -Make decision

Bud, Was thinking the same. Thanks for the reply. I'll talk to them today about transport and get a better feel for how that part would fare.

Ha 69.... I know what you mean. I don't post on here, but I have been an avid reader for years. I wouldn't be modifying the webs or cutting and chords. I'd just be adding to it. We have "code" here, but it's all just default national code. Inspections occur after it's complete, if they decide...

Yes, I understand a manufacturer will make them correctly... I found a perfectly sized set of new 26' trusses for sale for an excellent price (with gable end walls @ my desired pitch). But I don't want to cut corners on the roof structure and end up with something unsafe, and/or dumb looking in...

Hi. I have a truss question. I can't find a definitive answer on it. If my walls are 24' wide, is it possible to use 26' trusses? The extra 12" on each side would be used as additional overhangs. I'm not sure how far back from the ~6" bearing point a truss can be placed on a wall. If the bearing...

Re: Rick's Audi Double Does anything actaully happen is this garage, or is this fancy space for show only. It doesn't appear as though much happens. Maybe these pics were new before a car was driven into it. IDK... What are all the little bottles lined up on hooks for?
