The right siding does help insulate a house in New England. This is especially true of foam-back options with built-in rigid insulation, installed by Coastal Windows & Exteriors.
Insulated siding reduces heat loss and improves your home’s energy efficiency by creating a continuous thermal layer across your walls. Unfortunately, standard hollow-back siding offers almost no R-value. Foam-back and energy efficient siding options directly address that gap.
What MA, NH, and ME Homeowners Need to Know About Siding and Insulation
- Air Tightness Gain: Installing insulated siding can improve a home’s air tightness by an average of 25%. That improvement reduces drafts and lowers heating and cooling costs year-round.
- Under-Insulation Problem: About 89% of U.S. homes are under-insulated. Upgrading to insulated siding is one of the most accessible ways to address wall-level heat loss.
- Foam-Back Advantage: Foam-back vinyl is the most energy-efficient siding option available. The rigid foam layer adds R-value and creates a stronger, flatter panel face compared to standard vinyl.
- Energy Bill Impact: Massachusetts households spend roughly $600 per month on energy bills. Improving wall insulation through energy efficient siding directly reduces that ongoing cost.
- Weather Barrier Role: A quality house wrap installed beneath new siding reduces air infiltration and supports overall insulation performance. It works alongside foam-back panels for a complete thermal system.
- Popular for Good Reason: Vinyl siding holds between 38% and 41.5% of the total U.S. siding market. Its affordability and insulation options make it the top choice for energy-focused homeowners.
