Product Overview

Choosing The Right Insulation

Faced Insulation

Faced

Face insulation uses kraft paper vapor barrier to control moisture transmission between 
walls and floors 

*Check your local building code for requirements
Unfaced Insulation

Unfaced

Unfaced insulation does not have a vapor barrier; used over existing insulation in the attic, or where moisture control is not needed

Rolls Insulation

Rolls

Continuous rolls are easy to transport and can be cut to length; great for large areas

Batts Insulation

Batts

Come in pre-cut lengths for faster installation and each package contains more square feet than rolls; ideal for framed cavities

Blow-In Insulation

Blow-In Insulation

Installed using blowing machines, best for adding additional insulation in attic

Regional R-Values

Is this paintable so the pink and directions don't show? Indoor use, indoor Latex paint?
Asked by: MT
Yes, latex works great, you can peel the plastic top sheet off. Foam cuts great with a hot knife.

I was thinking of glueing or screwing this to the ceiling of my garage because are living room is above it and I feel like are living room never feels like it should and that it is harder to heat and cool. Will this product work or help enough to be worth it?
Asked by: Staylor
Hello Staylor, Foamular may be used in this application. We recommend using screws with caps to preserve the integrity of the product. Also, Foamular must be covered with a thermal barrier such as drywall. Thank you for your inquiry!

Can this be used for the underside of an outside deck that I just in closed. I put in a subfloor over decking and tiled it.. underside is exposed on one side only..de k is 6ft off ground.
Asked by: Joe
Hi Joe, while Foamular may be used in this application, we do not recommend leaving it exposed as it is a combustible product. Thank you for your inquiry!

FOAMULAR 150 2 in. x 4 ft. x 8 ft. R-10 Scored Squared Edge Rigid Foam Board Insulation Sheathing is rated 4.9 out of 5 by 88.

After researching the net for insulation not only for a crawl space and a basement I felt this would be the best product for the application. This was easy cutting this Formular 150 R-10 2" insulation in any dimension via a Olfa knife, circular saw and or a table saw. I completed most of my cuts prior to installation and installation was much easier and time efficient. I have already completed the installation 11/23/18 on the crawl space (encapsulated the crawl) and have already observed a savings in heating costs by 18% and the floors are much warmer by 8 degrees. I no longer smell the dank crawl space and the interior environment of the house has improved 100%. I am not encapsulating the basement; however, I will use this on all of the walls and fascia boards to effectively do the same as the crawl. I have calculated the return on investment at approximately 18 to 24 months. I would highly recommend this product and it definitely met my expectations.

I use this stuff to air seal walls and ceiling spots. Cut to size and then seal in w/ my Great Stuff PRO gun. On brick walls I fill the void between brick and studs with ROXUL safe n sound and then seal the stud void w/ foam. This gives me a fire block, fills the void eliminating a home for bugs/critters, makes wall air/water tight. Also if you expose studs go ahead and treat them w/ borate to kill any termites that try to nibble on your framing..just paint the bottom 2-3ft w/ it. This 2 inch variant of the Foamular translates to less cutting for me. It takes 3 inches to fill a 2x4 stud wall, I wish they sold the 3" thickness then I'd only have to cut one time. This does does dull utility knives quickly just a heads up buy an extra pack of blades. Attached picture shows this product along with the other foam that has a radiant barrier. I use 2 layers of foamular along w/ the radiant barrier version in most areas.

Used this in the attic for the areas that didn't have the height for proper R value. Underneath my AC system was only 8" from the ceiling. 3 sections of this gave me r30 value. The builder didn't even put insulation under the AC system. That's was a huge loss of heat in the winter. Also cut smaller sections to be used near roof edges and on the top plate. r-10 on the top plate is much better than nothing at all.

I am putting it up on my basement walls, painted block and using the PL 300 Foam Board adhesive it sticks great. It's sturdy to work, it with takes a beating hauling it around and cutting it is very easy. A hand saw and a jab saw for small cuts gets the job done. Keep a shop vac handy it is messy.
