How Insulated Siding May Help
- Continuous Coverage: Foam backing helps reduce heat loss through wood studs that traditional siding leaves exposed.
- Air Tightness Boost: Insulated siding may improve a home’s air tightness by an average of 25% per ENERGY STAR.
- Year-Round Comfort: Indoor temperatures may feel steadier across the coldest Januarys and warmest Augusts.
- Potential Utility Relief: Households spend about $600 each month on energy bills, so any envelope improvement matters.
- Long-Term Value: 89% of U.S. homes are under-insulated, which means most homeowners stand to gain comfort and potential savings.
