- IECC Performance: Compared to homes built to 2009 International Energy Conservation Code standards, insulated vinyl cuts heating and cooling energy use by 2-7%. It’s a real upgrade in thermal protection.
- Cost Comparison: Standard vinyl siding runs about $17,590 nationally, and insulated vinyl adds $2,000-$4,000 to the project. Here’s the thing though, you’re getting 97% ROI, plus ongoing energy savings that offset the extra cost over time.
- Ten Times Refrigerator Savings: This one puts it in perspective. The annual energy savings from R-2.5 insulated siding equal roughly 10 times what you’d save by swapping your old fridge for an ENERGY STAR model. For existing homes, it’s 5.5 times the savings!
- Cold Climate Benefits: New England throws everything at your house, extreme temperature swings, harsh winters, coastal weather that never lets up. Insulated vinyl siding is built for exactly that, keeping your home comfortable and energy-efficient through every season.
