How to Guide

Homeowners consistently rank energy efﬁciency as a high priority

when purchasing a new home. That’s understandable, since the heating

and cooling bill is the second highest monthly payment after the

mortgage for many families. Most say they are willing to

spend more for a home that will deliver energy

savings year after year.

Cavity insulation is a good start, but it’s not

enough. Wood framing, ducts, wiring and

plumbing – all poor insulators – make up more

than 25 percent of a wall’s surface. In a typical

home, that’s the equivalent of leaving an entire wall

uninsulated. With an R-value* of approximately 3.0 at

nominal 1/2", STYROFOAM™ Brand Residential Sheathing

Extruded Polystyrene Insulation on exterior walls boosts the

effective R-value of the wall by 20%.

Protection Against Moisture And Air Extruded polystyrene foam insulation like STYROFOAM™ Brand Residential Sheathing is inherently resistant to moisture, which can wreak havoc on other building materials. Moisture can compromise the performance of cavity insulation and damage drywall, wood framing and OSB or plywood sheathing.
