What type of adhesive caulk can be used to adhere to sheathing to wood studs? (of course nails would be used too, but this is just for initial stick and hold to provide time while installing to nail it fast).

What type of adhesive caulk can be used to adhere sheets to another sheet to double up a layer for extra R-value?

I have been told that some types of adhesive caulks will dissolve the foam and others are "safe" to use on the foam.

Thank you!

Answer: 
As a rule of thumb, rigid foam insulation can be adhered with any construction adhesive that is low VOC/low solvent so as not to dissolve the foam. Most of these will say they are suitable for use with polystyrene, polyethylene, or rigid foam board, and include Liquid Nails Heavy Duty construction Adhesive (LN-903), Loctite PL375 Heavy Duty, and OSI F-38 Drywall Adhesive.

Do NOT use polyurethane adhesives as these are solvent based and will eat the foam.
That being said, the RMax product is foil faced on both sides protecting the foam from the adhesive, so most any adhesive will be fine. The before mentioned LN-903 is a good all-around choice.

Hi DanFrontier, you're correct about some adhesives can melt the foam board. I have listed a couple of links below to show you the foam board adhesive. This is really good adhesive.

For an attic space, cut in strips the width of the space between ceiling rafters (usually 22-1/2") and adhere to the back of the drywall ceiling between the rafters using adhesive.
For both methods, use spray foam (polyisocyanurate) like great stuff and seal the edges of each foam panel with the surrounding joist/rafter for a high-quality "poor mans" spray foam result. Read Less

Hello yogendra;
Here is a link to the installation guide for Thermashealth. On page 3 you will see instruction on how to install on ceiling and information about exposure to flames. You must check your local municipal for codes. This is flamable and must be covered with at least 1/2 gypsum board.

Rated 4.7 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by Best Price Best Quality Best Value I take my hat off for Home Depot. I have searched everywhere for affordable RMAX. Home Depot is the only place that even comes close to providing prices that are reasonable. I don't cut corners on quality but don't want to have to take out a bank loan when having to pay for needed supplies. Home Depot has served us well in this regard. I will be back again and again. Thank you. August 10, 2016
Rated 5.0 out of 5.0 by Better then Great stuff Amazing product this is the standard for high performance insulation. Very easy to work with for my first time,score and snap like drywall or use very large dewalt razor knife and straightedge to cut all the way thru. I taped seams using 3m 8088 or Siga wigluv and fastened with 3.5'' deck screws and Rodenhouse Plasti-Grip ci Prong Washer. It should be available at every HD but its not. Closest in stock HD to me was 1200 miles away so I drove and got a full penske truck load. 1 pallet special order minimum at my New Orleans HD and $13more per sheet not cool! But its the best price thru HD for polyiso anywhere. December 30, 2015
Rated 5.0 out of 5.0 by Good product I insulated a laundry room with the R13 foam board and the job came out great. The cold room is now warm. Much easier than framing and sheetrocking. It is still hard work to move all of the electrical and plumbing, but was made easier using Sharkbite couplings. Not so bad. Homeowners were very pleased with the end result. Material is strong enough to adhere strips of wood for shelving. Tape seems with clear tape. Adhere to wall with large construction adhesive. Much more cost effective over spray on foam. Use hand saw to cut material. Cut outside as there will be thousands of foam particles that will fall off. I will use again. Material is waterproof and is reflective on both sides. A plus. December 24, 2014
Rated 4.0 out of 5.0 by great material very rigid product, easy to cut with a jigsaw. Used between existing joists and easy to press-fit when cut properly, no fasteners required. Cooled room by at least seven degrees over the batt insulation it replaced. Foil took a chalk line well. Easier clean up than coarser foam board, less static. It was pricey, but the thickness saved me a lot of install time. June 16, 2015
Rated 5.0 out of 5.0 by R13 in only 2 in. I purchased this rigid insulation to insulate a cinder block basement wall. The sheets were easy to cut and I achieved R13 in only 2 in. of space as compared to extruded polystyrene, which is only R10, and for the same money. My only disappointment was that I planned to use construction adhesive to install for the short term, but this stuff had a slight bow from the store shelf and the polyiso it is too rigid for the adhesive to adhesive to flatten it out, so I ended up using furring strips and 1/4" x 3-3/4" flathead Tapcons to anchor to the block rather than adhesive, which was my long term plan anyway. Not the products fault, but thought you should know how it behaves. Also, tape the seams with the nashua foil tape and fill any large gaps with great stuff (same polyiso product). January 5, 2015
Rated 4.0 out of 5.0 by Good material. Installs easy Installs quite easy. Use extra fine tooth wood saw to cut to size. When picking up material from store INSPECT IT for damage to the corners and sides! The do not pay much attention to the fact that this board is quire fragile and it gets damaged easy if mishandled. REMEMBER YOU PAY $35!!!!! + TAX A PIECE FOR THIS STUFF! January 27, 2015
