Go Green with Insulated Vinyl Siding

Go Green with Insulated Vinyl Siding

Windows, heating and cooling systems and air sealing and insulating systems are essential elements for building energy-efficient homes and providing customers with indoor air comfort. If a home's building envelope isn't properly sealed, it is difficult to prevent energy leaks. Through thermal bridging, a home's wall studs act as a passageway for heat and air to escape, reducing the insulating value of the entire wall and wasting energy when heating or cooling a home. In fact, according to the U.S. Department of Energy, air leakage can account for 30% or more of a home's heating and cooling energy. "Continuous wall insulation is crucial to fully seal a home's exterior and protect against heat loss," said Jerry Blais, vice president of marketing, Ply Gem siding group.

"Insulated vinyl siding, which is backed with polystyrene foam to increase a wall system's R-value, is one solution that helps reduce the impact of thermal bridging, adding a blanket of insulation over the exposed wall studs." Due to its effectiveness, insulated vinyl siding now complies with energy codes and qualifies for energy programs. The International Energy Conservation Code (IECC) includes insulated siding among materials that can be used as insulation outside the building to provide the required R-values for buildings in the coldest climates. ENERGY STAR also now recognizes insulated siding as a material to reduce thermal bridging and meet checklist requirements of products that help homes qualify to earn the ENERGY STAR Qualified Homes label.

Additionally, Ply Gem insulated vinyl siding products are NAHB Research Center Green Approved. For specific information on how insulated siding contributes to energy performance, builders can access "Insulated Siding as Home Insulation: Guide for Users and Energy Raters," created by The Vinyl Siding Institute (VSI). This free guide, available at, is designed to help trade professionals better understand the benefits of using insulated siding on homes. Beyond energy efficiency, here are other ways insulated siding benefits builders and home owners:

Low Maintenance

Vinyl insulated siding offers the look of real wood but does not require painting or staining. In addition, insulated vinyl siding acts as an exceptional dry wall system, making it resistant to mold growth and deterioration due to moisture absorption.


The foam insulation backing and wide-style clapboard design makes insulated vinyl siding an extremely durable and impact-resistant cladding option that improves flatness on the exterior wall for added aesthetic appeal.


With today's vast selection of profiles and advancements in color technology, builders can enhance exteriors with insulated vinyl siding colors that complement today's home trends. Blue, green or red colored siding provide "pop," which can make a significant improvement in the overall look of a home's exterior. Mastic Home Exteriors by Ply Gem Structure Home Insulation System is a premium insulated cladding option available in different lengths and extended color options to match various architectural styles.
