Adding Insulation to Siding

If you’re looking to improve your home’s energy efficiency, adding insulation to your siding is a smart investment. While some siding materials come with built-in insulation, other popular options like James Hardie fiber cement siding and LP SmartSide engineered wood siding do not. Fortunately, you can enhance the insulating properties of these materials by installing rigid foam beneath them.

Insulating your siding helps prevent thermal bridging, a common issue where heat escapes through the wooden studs in your walls. By adding rigid foam over the plywood sheathing before installing new siding, you can create a continuous insulating layer that reduces heat loss and improves overall efficiency.
