For most homeowners, insulated vinyl siding is one of the highest-value exterior upgrades available. Energy savings are possible with professional installation.

Why insulated vinyl siding delivers real value:

Continuous foam insulation covers the full wall: Standard siding leaves gaps at every stud. Foam-back siding seals the entire surface and stops heat loss at the source.
An immediate R-value increase of 5: A single 1-inch foam layer boosts your wall’s insulating power from day one.
Up to 25% of home energy lost through uninsulated walls: Insulated siding addresses one of the biggest energy drains.
5.5% average energy savings documented: A study of five re-siding projects found measurable savings after insulated siding installation.
Added comfort beyond the numbers: Fewer drafts, reduced cold spots, and a more consistent indoor temperature year-round.

Is Insulated Vinyl Siding Right for Your Home?

Top Recommendation: CraneBoard® Solid Core Siding® for homeowners who want the highest thermal performance. Its continuous foam core delivers the strongest R-value available.
Best for Budget: Standard foam-back insulated vinyl panels for homeowners who want meaningful energy improvement without the solid-core premium.
Best for Drafty Older Homes: Insulated re-siding paired with new house wrap for homes with little existing wall insulation.
