The key difference is a foam backing. Insulated vinyl siding adds a layer of rigid foam that improves energy efficiency and wall rigidity.

The key difference is a foam backing. Insulated vinyl siding adds a layer of rigid foam that improves energy efficiency and wall rigidity.

Standard vinyl siding is a proven, low-maintenance option that protects your home and never needs painting. Insulated vinyl siding does all of that and adds energy-efficient foam siding performance built into the panel itself. For homes across New England, that extra layer can make a meaningful difference in comfort and heating costs.

What Essex County Homeowners Should Know About Vinyl Siding Options

  • Standard vinyl: Regular Exterior Portfolio vinyl siding is a durable, co-extruded PVC panel engineered for low maintenance. It never needs painting, resists moisture, and carries an industry-leading Double Lifetime Warranty.
  • Insulated difference: Insulated foam siding adds a layer of rigid foam bonded directly to the back of the panel. CraneBoard® Solid Core Siding offers significantly more insulating power than fiber cement, wood, engineered wood, or brick.
  • Air tightness gain: Installing insulated siding can improve a home’s air tightness by an average of 25%. That reduction in air infiltration directly lowers heating and cooling costs year-round.
  • Energy efficient siding: Insulated vinyl is the most energy efficient siding option available for New England homes. It’s a smart upgrade for older homes on the North Shore with drafty walls or minimal exterior insulation.
  • Wall strength added: The foam core also improves the rigidity and impact resistance of the panel. That added stability helps insulated vinyl hold its shape through the temperature swings common north of Boston.
  • Same great colors: Both standard and insulated EP Vinyl come in the same Chromatix® color palette — including Espresso, Graphite, Indigo, Aspen White, Metropolitan Gray, and more. You don’t sacrifice style for energy performance.

Standard vs. Insulated Vinyl Siding: What’s Right for You?

Top Recommendation: Insulated foam siding for New England homeowners prioritizing energy efficiency and long-term comfort — the most energy efficient siding option available.

Best for Budget: Standard Exterior Portfolio vinyl siding at $18,000 average installed, with a 97% ROI and zero painting costs.

Best for Older Homes: Insulated vinyl for homes with minimal wall insulation — the 25% air tightness improvement delivers real, measurable energy savings.
