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

Can I use this to insulate my basement ceiling I want to cut it to size and place it inbetween the joists

Asked by: Moe
You could use this to insulate between your joists but it would be more expensive and time consuming than using regular batt insulation. In my opinion your basement ceiling should not need much if any insulation so it would be overkill. Also if you every need to remove the subfloor above then you will end up removing the insulation as well as it would be attached to the subfloor above. Good Luck!!!

Can I insulate the inside of a overhead garage door with this

Asked by: Rob
The product is not designed for this type of application. There are better methods to do this, a quick google search will provide those materials. If you have an attached garage and are trying to keep your home warmer, start by insulating the neighboring portion of your house first. If you believe those walls are properly insulated, I recommend purchasing a heat sensor and verifying your assumption.

Asked by: linda
Do you have termites and/or carpenter ants in your region? They will tunnel through materials without insecticides coating.
