Insulated vinyl siding is a vinyl panel with rigid foam permanently bonded to the back.
Foam-back vinyl is the most energy-efficient siding option for New England homes. The foam fills the gap between your siding and wall sheathing. This reduces thermal bridging through wall studs and creates a stronger, flatter panel face.
What MA, NH, and ME Homeowners Need to Know About Insulated Vinyl Siding
- Foam Bond: Rigid foam is permanently bonded behind each panel. This design fills wall gaps that standard hollow-back vinyl exposes to heat loss.
- Thermal Performance: Quality foam-back vinyl can add an R-value of up to 5 with a one-inch foam layer. That’s meaningful added insulation for cold New England climates.
- Air Tightness Boost: Installing insulated siding can improve a home’s air tightness by an average of 25%. Tighter walls help reduce heating and cooling costs year-round.
- Impact Resistance: Foam backing makes panels up to 5x more impact resistant than hollow-back vinyl. That’s a real advantage for homes facing hail, wind, and winter storms.
- Market Popularity: Vinyl siding holds between 38% and 41.5% of the total U.S. siding market. Insulated versions represent the premium tier within that category.
- Zero Painting Required: Vinyl siding needs only mild soap and water for periodic cleaning. No painting, caulking, or staining is needed over its lifetime.
