The same material we use to wrap our bodies—in the form of Gore-Tex clothing—or to ship our goods—in overnight packages—can also wrap our building envelope. Plastic house wrap, coupled with insulating plastic foams and sealants, adds another layer of protection to a home. House wrap has been shown, in the Franklin Associates Study, to reduce infiltration of outside air by as much as 10 to 50 percent. By reducing air infiltration of outside air, we reduce the energy required to heat or cool a home—saving the average homeowner thousands of dollars over the life of a 30-year mortgage. House wrap insulation can also help reduce airborne pollutants that otherwise penetrate your home’s envelope.

Jack Armstrong, of BASF’s Global Building Materials, shows how energy efficiency can be enhanced by smart uses of the many varieties of plastic insulations, sealants, stabilization foams, window glazing, frame cladding and much more. Originally given at a press Conference on the Mall in Washington, DC for the Solar Decathlon, the subject matter goes to the heart of Near Zero Energy Homes.
