I’ve got an 1860’s timberframe barn with vertical T&G siding. I want to insulate it and move my WW shop into it. Because of the cracks and knotholes in the siding, I feel Tyvek inside the sheathing wouldn’t hold up to weather. I’ve considered 1/4″ PT plywood, roofing felt, foam board, etc.
What can I apply to the inside of the siding and between the posts for keeping weather out and heat in?
There is also an open crawl space under the T&G maple floor that also needs insulation. Ideas?

My suggestion: Keep it as a dance hall and gin mill!!...more profit in that!!!

Dale, seems like a tough question for us to answer over the Net. The question of a field inspection comes to mind. Now exactly how MUCH of the original gin-mill stocks remain? Our advise seems much more cogent after a few libations!
Seriously, sprayed in place Urethane Foam? You'd have to employ a insulation contractor to do so, and the cost is higher, but it may solve your problem. Or how about adding battens to the T&G siding for a board and batten effect, closing the seams, and conventionally insulating afterward.

DALE,
I JUST GOT DONE INSULATING A BARN SUCH AS YOURS. I STARTED WITH TYVEK AND THE FURRED OUT THE INSIDE WITH 2X4S AND THEN INSTALLED 1 1/2" ISO INSULATION BETWEEN THE 2XS AND THEN COVERED THE ENTIRE INTERIOR WITH THE TONGUE AND GROOVE PINE. AFTER THAT I CAULKED ALL THE JOINTS WHERE THE T&G TOUCH THE BEAMS TO GIVE IT A FINAL SEAL. IT LOOKS REALLY NICE AND I PROBABLY HAVE AN R15+ VALUE.
*DaleMy first question is how much do you intend to spend on this project? Insulspan panels are what we use in the timberframe bussness. They are expencive but allow you to insulate and sheet in one step. They are attached to the outside of the frame over your boards with 10 or 12 inch spikes or screws. This gives a great effect in that you can see all of the frame and the wall boards from the inside, the outside is osb. Properly installed they are structural but with a frame inside of them they are very strong They come 4 or 8 feet wide and as long as you need or can handle, and the thickness depends on what "R" factor you require. The ones we use are R 26 and except a 2X6 for the walls and R42 and except a 2X8 for the roof. The panels themselves are 5 1/2 " of styrofoam sandwiched between 7/16 asponite so nailing is no problem. The only thing is the price, in Canada we pay about 5 bucks a square foot for the stuff. Another suggestion is to baloon frame the outside and insulate that, but by the time you buy the wood, insulation,outside sheeting or siding, and the labour of a proper vapour barrier the insulspan gets looking a lot better. It sounds like a cool old building, good luck with what ever you decide.
