Introduction to Roof Sandwich Panels
Roof sandwich panels are composite building materials that consist of two outer layers (usually metal sheets such as steel or aluminum) and a core material in between. The core material can be made of various substances like polyurethane (PU), polystyrene (EPS), mineral wool, or rock wool. These panels are widely used in the construction industry for roofing and wall applications due to their excellent insulation properties, lightweight nature, high strength, and ease of installation. They offer significant energy - saving benefits, enhance the overall thermal performance of buildings, and can be customized in terms of color, thickness, and size to meet different architectural requirements.
