New insulated siding can make a real difference in how comfortable a home feels all winter. Coastal Windows & Exteriors is a woman-owned exterior remodeling company that has completed 7,000+ installations since 2011, serving 730+ towns across Massachusetts, New Hampshire and Maine with professional insulated siding installation. Energy savings are possible and indoor comfort often improves with professional installation.
How new siding contributes to a warmer, more comfortable home:
- 9 out of 10 U.S. homes are under-insulated — Adding insulated siding is one of the most accessible ways to address this gap.
- A 1-inch foam layer adds an immediate R-value increase of 5 — Continuous insulation blocks heat loss across the full wall, not just between the studs.
- Heating and cooling energy use may reduce by 2 to 7% — Compared to older uninsulated walls, insulated siding can deliver meaningful seasonal savings.
- Fewer drafts and cold spots throughout your home — Thermal bridging at the studs is eliminated, so walls feel consistent and comfortable all winter long.
- Air infiltration reduction cuts energy consumption — Sealing the wall cavity reduces the amount of conditioned air that escapes your home.
What Comfort Improvements Can Homeowners Expect?
- Top Recommendation: CraneBoard® Solid Core Siding® for homeowners who want the greatest comfort improvement — its foam core stops heat loss directly through the wall studs.
- Best for Budget: Standard insulated vinyl siding for homeowners who want noticeably warmer rooms without the cost of a full solid-core upgrade.
- Best for Drafty Older Homes: Foam-back re-siding paired with new house wrap for homes with aging walls and little existing insulation.
