What is Wood Insulated Siding?
Wood insulated siding is a composite exterior cladding material combining the aesthetic appeal of wood with the energy-efficiency benefits of insulation. It’s constructed from a core of rigid foam insulation sandwiched between two layers of wood, typically offering a durable and attractive exterior finish. This combination results in a product that enhances both the visual and thermal performance of a building.
Wood Insulated Siding Composition
Wood insulated siding typically consists of a core layer of expanded polystyrene (EPS) or polyisocyanurate (polyiso) foam insulation. This insulating core is then encased in two outer layers of wood. The outer wood layers provide the weather protection and aesthetic appeal, while the foam core significantly improves the building’s thermal performance. The thickness of the insulation core and the type of wood used can vary depending on the manufacturer and the desired performance characteristics.
Manufacturing Process of Wood Insulated Siding
The manufacturing process involves several steps. First, the foam insulation core is cut to the desired size and shape. Then, the wood cladding, usually pre-finished or primed, is applied to both sides of the foam core using adhesive and mechanical fasteners. The edges are often sealed to prevent moisture penetration. Finally, the panels are cut to the required lengths and packaged for distribution. Quality control checks are implemented throughout the process to ensure consistent product quality and dimensional accuracy.
