PUF panel roofing for existing buildings by Pristine Steel Buildings. PUF panels in prefabricated construction provide insulation and protection for existing buildings. PUF panel sheets are polyurethane foam sheets that can be used in existing buildings for protection and thermal insulation. They are commonly used in institutions, sports arenas, hospitals, industries, and co-working spaces. PUF panels protect the indoor environment from ambient heat and sunlight. They keep the environment cool and protected from extreme weather such as wind, rain, or snow. We ensure that the PUF sheets are installed properly and that the appropriate sealants and caulking materials are installed. Additionally, our team inspects the PUF sheet after installation to ensure there are no visible signs of damage or wear. We also make sure it has been properly sealed and is not exposed to moisture.
