Insulation Foam Chicago which is available in rigid panels or boards is referred to as rigid insulation. Polystyrene, polyisocyanurate, and polyurethane are just a few of the components used to make it. Expanded polystyrene (EPS) and extruded polystyrene are the two materials most often used in rigid insulation (XPS). The high R-value of rigid insulation, which is a metric of thermal resistance, is well-known. This indicates that it functions well as insulation, retaining heat in the winter and keeping it out in the summer. Applications for rigid insulation in construction include walls, roofs, and foundations. Due to its versatility and ease of cutting to meet the required dimensions, it is a viable option for new construction. It may also be used in conjunction with other forms of insulation. Additionally, it is used to insulate warehouses for cold storage, refrigerated vehicles, and shipping containers. It is also utilized to insulate commercial and industrial structures according to insulation contractors Chicago.
