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?

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!

I used this foam board to insulate a small wellhouse that already had the pipes and pump heat taped. Just wanted to protect it from strong cold wind. The foam sheet was easy to cut with a long sectioned style box cutter with repeated angled cuts along the desired line. The foam board also has pre-scribed lines to assist in cutting the board lengthwise into 16 or 8 inch wide strips but I found that the resulting ragged edge was harder to use even though it was straight!

The pre-scored lines make these sheets much easier to manage. Just press and snap at the lines. The extruded board is also easier to cut with less mess than the pressed white styrofoam.
