Rigid foam board is a type of thermal insulation panel made from polymer-based materials such as EPS, XPS, or PIR. These boards are designed to reduce heat transfer through building envelopes, improving overall energy efficiency. Rigid foam board is widely used in walls, roofs, and foundations because it provides consistent insulation performance, high compressive strength, and good moisture resistance. Construction professionals prefer rigid foam insulation because it is lightweight, easy to install, and available in a variety of thickness options to meet different building requirements.
