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

Regional R-Values Map

The Department of Energy recommends different insulation
levels based on regional climate zones to increase energy efficiency

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!

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.
