I've got a general question about potentially using SIPs.
I'm going to be building a 42' x 42' timberframe barn here in Maine that I want to make sure is very well insulated. I understand that the timberframing provides all of the necessary structural support, so I wouldn't have to rely on a shell made from SIPs or ThermaSteel to provide structural walls. What would you folks suggest I use as a shell on the timberframing if I wanted to maximize the insulative qualities of the shell itself? It would be great to have walls that are an R-40 or above. I also want to make sure that whatever option I go with is not going to be vulnerable to delamination.
Thanks in advance for the feedback.

| I think SIPS are considered the ultimate sheathing for timber frame construction, by the timber framers. Since they can be non structural in nature, you can order them with drywall or some other interior skins in lieu of the osb. (Or in addition to the osb, if you wish). They also do not have to be 'certified' as structural panels, which could reduce the cost of these panels. I know that General Panels' Johnson City TN plant specializes in this type of panel. Contact Butch Johnson for more information on the options available. (bjohnson@generalpanel.com or 423-747-8710). |

Thanks for the feedback.
Being in Maine, I'd most likely opt for a supplier who's local--or at least in N. New England--so I can avoid the excessive freight charges. I'm assuming I've got a number of options up this way in addition to Foard Panel.
I appreciate the recommendation.

John,
Here's another option to consider. You can use the SIP's as the structural component of you building and use other wood to make the timber frame look. Now you can have the timber frame look, an excellent insulated shell, and I think it will be better insulated and less expensive than clading a timber frame.

I appreciate the
suggestion. I'm committed to going with a classic timber frame
construction for the barn. I'm building for posterity. I feel confident that in
another 100 years, the structure itself will still be just as sturdy as
it will be the day it's erected. No one knows for sure how a SIP
will age over 100 years, or for that matter what its structural
integrity will be. I'd rather go with the tried and true.
I'm curious though, how would going with a SIP construction with a faux timber frame interior be 'better insulated' than going the route I'm proposing? I'd still choose to use the same SIPs. . .

I have worked with a company called Ray-core (www.raycore.com) that may help with some of your obstacles. They manufactures a SIP that integrates studs into the panel so you get awesome structural strength will getting a R-42 on 2x6 walls. Their website says that you can get R-52 out of a 2x8 panel, but I have not used the 2x8 myself, at least not up to this point. I realize support is not your biggest concern, so maybe that can do studs on 24" centers or possibly 48" on center. From my understanding of their product, the less studs you use, the greater the increase in R value.
These panels would also solve your problem about delamination because they do not laminate like a traditional SIP, they inject the foam while in a press so there is no chance of delamination, as opposed to gluing foam to OSB. They come pre-wrapped in reflective vapor barrier so thay is also going to give you a bonus.
Check them out, it worked great for me and I think it would help with several of your issues. They are easy to work with and will help give you ideas without any obligation.
Good luck |
