The key difference between regular and insulated vinyl siding is a foam backing—insulated vinyl adds a layer of rigid foam that improves energy efficiency and wall rigidity. Coastal Windows & Exteriors is a woman-owned exterior remodeling company serving 730+ towns across Massachusetts, New Hampshire and Maine, with 7,000+ installations completed since 2011 and both standard and insulated vinyl siding options.
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 performance built into the panel itself. That extra layer can make a meaningful difference in comfort and heating costs.
What 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. It’s a smart upgrade for older homes 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 temperature swings.
- 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.
