Polyurethane Foam (PUF) panel is a layer of material that is sandwiched between GI metal sheets. These panels have many applications and are generally used for making living shelters, especially prefabricated homes, and portable cabins. PUF panels are good heat insulators so they can protect the inner environment from ambient heat and sunlight and can keep the indoors cool. This means lesser energy will be used to keep the premises inside the structure cool which can save costs incurred in indoor cooling during hot weather.
