Insulated vinyl siding improves home air tightness by 11% on average with 5.5% energy savings in re-siding projects.
This upgrade reduces heating and cooling costs while enhancing comfort year-round. Insulated vinyl siding costs more than standard vinyl’s $17,590 average but it delivers superior energy efficiency and ROI benefits. So, yes, you should consider insulated vinyl siding for your home!
What New England Homeowners Need to Know:
- Air Tightness Improvement: Insulated vinyl siding makes your home 11% more airtight on average. That means fewer drafts, less air sneaking in, and steady indoor temps all through those brutal New England winters!
- Energy Savings: You’ll see about 5.5% in energy savings on heating and cooling after a re-siding project with insulated vinyl. When Massachusetts households are spending roughly $600 a month on energy, that adds up fast!
- 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.
