Insulated vinyl adds a rigid foam backing to standard panels. It typically costs more than standard vinyl (editorial estimate $6–$11/sq ft installed) and adds modest insulating value to walls, helps bridge studs and makes panels more rigid and impact-resistant.
Savings depend heavily on your existing wall insulation and climate — biggest in cold climates and leaky older homes. Be wary of contractors promising specific percentages without an energy assessment.

Frequently asked questions
Does insulated siding really lower energy bills?
It can modestly, especially in cold climates and poorly insulated homes, but results vary; it's not a replacement for wall insulation.
