What type of insulated panel has a layer of insulating foam between two OSB or plywood panels?

The type of insulated panel that has a layer of insulating foam between two OSB (Oriented Strand Board) or plywood panels is known as a structural insulated panel (SIP). These panels are specifically designed to provide both structural support and insulation, making them highly efficient for construction. The combination of the outer wood materials and the foam insulation allows for high strength and thermal performance, which is crucial in various building applications.

Structural insulated panels are widely used in residential and light commercial construction, providing benefits such as reduced air leakage, improved energy efficiency, and a quicker construction process. They serve as both the framing and insulation in walls, roofs, and even floors, making them a popular choice among builders and architects aiming for sustainability and energy efficiency in their projects.

The other options, though they indicate some type of insulated panel, do not accurately describe the specific construction of a panel with insulating foam sandwiched between two OSB or plywood layers. Understanding the function and composition of structural insulated panels is essential for making informed decisions about construction materials in a building project.
