ENERGY STAR® Home Sealing – Improving the envelope of your home
For the average U.S. household, about half of the energy costs go toward heating and cooling. These costs can be significantly reduced by improving the “envelope” or outer shell of your home. ENERGY STAR recommends a process of effective air-sealing techniques and additional insulation called Home Sealing to improve the envelope of your home.

What are the benefits of an energy-efficient envelope?

  • improved comfort by reducing drafts
  • savings on heating and cooling bills
  • reduced noise transmission into your home
  • fewer gaps and cracks for pollen, dust, and pests to enter

As an ENERGY STAR partner, Progressive Foam Technologies’ flagship product, the Fullback Thermal Support System, along with other EPS products produced by Progressive Foam, are ENERGY STAR qualified products as a part of the Home Sealing effort.

The Vinyl Siding Institute
The Vinyl Siding Institute (VSI) is the trade association for manufacturers of vinyl siding and suppliers of raw materials, equipment and services to the vinyl siding industry. As a member, Progressive Foam has worked closely with members of the Technical and Marketing Committees to test our products for approval for use with their vinyl siding. Progressive Foam has obtained approval from all the producer member companies of the VSI.

UL® Classified
Progressive Foam contracts with Underwriters Laboratories (UL) to serve as our ongoing third-party testing agency. We test our products routinely under this protocol. In addition, periodic non-scheduled inspections are conducted by UL personnel to ensure that our foam either meets or exceeds the performance requirements for density, flexural strength, compressive resistance and flammability specified by various building codes.

The “R”-value, permeability and structural integrity of Progressive Foam products are covered by a lifetime warranty which can be transferred with ownership of the building where they are installed.
