My husband has been looking everywhere for this product. The website says it is "In Store Only" but it is not available within 100 miles from any zip code I enter - and I have entered codes out of state. Please let me know how this can be ordered for our basement project, or if another similar product has replaced this. Thank you in advance.

Answer: 
i contacted the representative at my local home depot pro desk. They did not have a clue as to what i was asking for. They finally had to call owens corning directly. i need 10 sheets for one wall in my basement. owens corning will only ship a quantity of 128 sheets or more. What good is it having a user friendly product if you cannot buy it.

Basement walls with a beveled bottom portion of the wall

This question is from FOAMULAR 1-1/2 in. x 2 ft. x 8 ft. R-7.5 InsulPink Furring Lap Insulation Sheathing

In my basement, the bottom four inches or so are sloped inward, probably due to some masonry designed to prevent water entry at the wall seam. In addition, there is additional masonry (1/4 inch or less) on the bottom four feet of the wall, probably for the same reason. the result is a wall that is not flush from top to bottom. Would this product be able to be attached directly to the basement wall or would you suggest framing the walls and using another product as a moisture barrier/insulator? If so, what product would you suggest? Thank You!

Answer: 
Dear Scott: Yep, sloped walls create a number of problems. A couple of suggestions:
(1) Poly moisture barrier: Start with a thick poly moisture barrier, laid against the concrete wall and carefully sealed at the top, sides and seams with DAP 230 -- to block air and moisture leaks.
(2) Foam board: Mount 1" foam board on the concrete wall, down to the level where the wall begins to slope inward. Seal all Read More
Dear Scott: Yep, sloped walls create a number of problems. A couple of suggestions:
(1) Poly moisture barrier: Start with a thick poly moisture barrier, laid against the concrete wall and carefully sealed at the top, sides and seams with DAP 230 -- to block air and moisture leaks.
(2) Foam board: Mount 1" foam board on the concrete wall, down to the level where the wall begins to slope inward. Seal all of the edges and joints carefully with DAP 230. Then add a second 1" layer of Foamular, which will probably reach down to the floor. If a gap remains, fill it with the 'Windows and Doors' version of Great Stuff, which remains flexible.
(3) Build your 2x wood wall in front of the foam board, so that the studs do not touch the concrete. To boost insulation, fill the stud bays with Roxul rock wool, which provides R 4.2 per inch.
(4) Also cover your floor with a poly vapor barrier and at least 1" of foam board -- and seal all of the joints and edges carefully with DAP 230 and Great Stuff. Lay 3/4" plywood on top as the nailing / glue surface for your flooring, with the panels perpendicular to the foam board seams. Seal the plywood carefully with DAP 230.
(5) If there is any hint of a water problem in your basement however, start with DriCore panels -- and make sure there is a drain / sump pump to remove water leakage. Then install the foam board and plywood, if you have sufficient head room.
(6) (4) Also read up on fire blocking, which is required at the top of basement walls, stairs, etc. Do a Google search for "How to firestop your basement" from Contractor Kurt. Roxul rock wool is a good solution (also available at Home Depot). You can stuff it into the gap at the top of the wall and into the end of floor joist bays. Rock wool is much denser than fiberglass, molds kind of like clay, and stays where you put it.
I hope this is helpful,

Answer: 
Scott, it's hard to say if the 1 1/2" thick Insulpink will be flexible enough to be adhered directly to the contours of your wall. Also, I'm thinking, if you were able to adhere the Insulpink directly to the wall, you would run into the same problem when trying to adhere the drywall. We definitely recommend adhering Foamular directly to the foundation wall without any air gaps. If there are air gaps, Read More
Scott, it's hard to say if the 1 1/2" thick Insulpink will be flexible enough to be adhered directly to the contours of your wall. Also, I'm thinking, if you were able to adhere the Insulpink directly to the wall, you would run into the same problem when trying to adhere the drywall. We definitely recommend adhering Foamular directly to the foundation wall without any air gaps. If there are air gaps, there will be a chance that warm moist air could get behind the Foamular and hit the cold foundation wall possibly creating condensation issues. It is up to you if you want to try this, and it's hard for me to assess the situation without physically being able to inspect. Another option would be to use Foamular 150 adhered directly to the foundation wall, frame a wall against the Foamular, and add a Kraft Faced insulation filling the cavity with the Kraft facing towards the inside of the room, covered with drywall which is properly sealed. I hope this information is helpful. If you have any further questions, please feel free to contact a representative at your local Home Depot ProDesk and they will be happy to assist you.

Answer: 
Dear Kevin:
Yes. Foamular foam board is XPS -- which is water resistant, unlike polyiso foam board which absorbs water. So Foamular is ideal for external applications, e.g. walls and roofs. On the Foamular website you can find related application notes. (It is puzzling that the Owens Corning rep said it is designed for interior applications only, contrary to their website.)

On the Foamular website you can find related application notes. (It is puzzling that the Owens Corning rep said it is designed for interior applications only, contrary to their website.)
A few tips:
(1) You don't need to sheath the wall with plywood over the Foamular. We recently did a deep remodel of a house in Massachusetts, for example, and wrapped the exterior with 2" Foamular panels. On top, we attached 1" x 3" strapping to mount the siding. A photo is attached. This is much cheaper and easier, and provides an generous air gap behind the siding that will allow it to dry.
(2) Use a Ramset (available at Home Depot) to shoot nails through the 1x3 strapping into the concrete block. (Be sure to wear ear and eye protection!) This will also fasten the Foamular panels securely to the block wall.
(3) Carefully seal the top and bottom of each panel to the block wall, to stop hot / cold air from circulating behind it and negating the value of your new insulation. Great Stuff foam and DAP 230 work well, depending on the size of the gap. Look for the 'Windows and Doors' version of Great Stuff in the blue can, which remains flexible as things expand and contract.
(4) Depending on your climate, energy costs and the insulation on the inner side of the block wall, you may want to double-up with 4" of Foamular for R20 -- the current standard for walls.
I hope this is helpful.

Owens Corning Insulpink was designed for interior basement wall applications, but it would be up to you if you wanted to use it as you described.

Your only points of attachment for the plywood would be along the 1x3 furring strip, which depending upon how you attach, may cause issues with the thin strip, but again it's hard to say for sure. Also when you begin nailing in the siding, more than likely you will penetrate the Foamular with all of the nails, and I cannot say if there will be any affect on the Foamular. I cannot recommend this because it is not a typical use for this product, or your application. It is up to you how you want to proceed. Thank you for your inquiry and good luck with your project!

Rated 5.0 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Hunting Cabin built a hunting cabin and instead of closing the 8 foot ceiling I left it open like a cathedral ceiling and placed this insulation between the ceiling rafters, they were 2 feet apart and this worked out great, room looks much bigger, but it is still insulated. Bring on the snow!! August 16, 2016
Rated 5.0 out of 5.0 by Easy to install, great product for money, no mess with traditional insulation Light weight, easy to cut, no mess as with traditional insulation nor small fibers to irritate skin. Using in basement to insulate outside walls in new kitchen build. Saw immediate difference in temperature of basement. We are doing all the work ourselves. July 10, 2014
Rated 5.0 out of 5.0 by Easy to work with and solid This stuff is very rigid (as the name would imply). I was stepping all over it and barely left a mark — good compressive strength. I used it between sleepers over cement and the difference was immediately noticeable. It was incredible easy to cut. I used a razor and circular saw, both with good results. A little pricey, but money well spent. July 21, 2014
Rated 5.0 out of 5.0 by Owens Corning Insul Pink Foamular I liked working with this product. It was easy to cut, there was no irritating dust and it fit easily in the bays between joists. The leftover waste was easily disposed of. The performance of the insulation achieved immediate results in moisture reduction and heat savings. I used it to insulate the space between the basement ceiling and the living space above in an older home with a very damp basement.l September 30, 2009
