Whether you’re considering doing it yourself or hiring a contractor, you may be wondering how to install siding. More specifically, you may want to add insulation under your new siding when it is installed to make your home more energy efficient, and are unsure how that will change the installation steps. The United States Department of Energy even says “when new siding is to be installed, it is a good idea to consider adding thermal insulation under new siding.”*

Siding products can have different installation instructions depending on the particular product being installed, so always be sure to follow your manufacturers instructions for your specific siding. Below are written instructions for how to install vinyl siding, fiber cement siding and other siding products over contoured and flat foam insulation products made by Progressive Foam.
