Energy-efficient insulated siding added to VSI Certification Program
Certified insulated siding must meet or exceed the industry standard for quality and performance (ASTM D7793), as verified by an independent, accredited quality control agency.
In anticipation of pending changes to the 2015 International Residential Code and the 2015 International Energy Conservation Code, the Vinyl Siding Institute has added insulated siding to its VSI Product Certification Program. These codes, once passed, will require insulated siding that has been certified. Certified insulated siding must meet or exceed the industry standard for quality and performance (ASTM D7793), as verified by an independent, accredited quality control agency.
Insulated siding, vinyl siding with manufacturer-installed rigid foam plastic insulation permanently adhered to it, forms a thermal bridge of continuous insulation around a home, so heat cannot escape through the studs and framing materials. The new international standard for insulated vinyl siding (ASTM D7793) also requires a minimum thermal resistance rating of at least R-2.0 and performance tests for weathering, windload, and impact resistance.
Colors of insulated siding can also be certified through VSI’s Program to meet or exceed ASTM D6864 or D7251, the industry standards for solid and multi-hued colors, respectively. Certified colors will resist major changes over time and exposure to the elements in a variety of climates, as verified by a two-year, outdoor weathering study.
“Certified insulated siding will readily appeal to homeowners who want energy efficiency,” said VSI President and CEO Jery Y. Huntley. “Aesthetically, insulated siding comes in a wide variety of colors to boost a home’s curb appeal. Functionally, the continuous insulation has been proven to help improve a home’s thermal performance — which can mean lower utility bills.”
