Summary: Insulated vinyl siding has foam insulation laminated to the back of regular vinyl siding that makes the siding more energy efficient, more durable, more sound proof, easier to install, and impact resistant.
Regular vinyl siding is subject to damage from impact, wind, and weather.
There is also a hollow space between the siding and the exterior wall that traps moisture and limits energy efficiency.
Insulated vinyl siding improves the appearance of your home, as the waviness associated with vinyl siding is reduced.
According to the National Association of Home Builders Research Center, the cost of insulated vinyl siding is about the same as the cost of non-insulated vinyl siding over ¾ inch foam sheathing.
Installation is easier as insulated vinyl siding is more rigid and won’t bow and sag as easily as vinyl siding, making it easier to measure, cut, and nail.
