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

Questions & Answers

Can it be installed before insulation and drycwall on remidel home.

We are doing a remodel. Can we put this up between studs before we install the insulation and dry wall ?
Asked by: Okie
It is meant to be placed under siding on the outside of the plywood. It is just extra insulation. Not meant for in between studs.

I am using this product on my concrete basement walls. Does it matter which side goes against the wall?

Asked by: R61457
Hello, When installing the Foamular, it does not matter which side goes against the wall. I would recommend installing the printed side towards the living space just in case you would need to locate which product or size is installed down the road.
