House Wrap

House wrap is a common type of insulation on new homes. The material is designed to keep out moisture and reduce drafts while simultaneously allowing the walls to breath. The wrap comes in rolls and is stapled directly onto the wall sheathing.

Sheet Insulation

Fan fold comes in foam sheets and is nailed directly to the sheathing. While fan fold has minimal insulation value, it does even out wall defects and cuts down on drafts.
