PUF Panel
WHAT ARE SANDWICH PANEL SHEETS?
Also known by the generic name of PUF sheets, sandwich panel sheets are prefabricated single pieces of rigid polyurethane foam sandwiched between two metal sheets. The PUF is glued to the metal sheets, providing an insulating effect. While sandwich panel roofing sheets are popular, they also find application in walling.
Because of its construction, sandwich panel sheets have an inherent advantage used for roofing. They include:
- High load bearing capacity at low weight
- Excellent and durable thermal insulation
- Absolute water and vapour barrier
- Excellent air tightness and free of thermal bridges which results in considerable energy savings.
- Surface finished facings providing resistance to weather and aggressive environments
- Capacity for rapid erection without lifting equipment’s; easier installation in hostile weather conditions
- Easy repair and replacement in case of damage
- Long life and very low maintenance cost
- Good sound insulation
- Reasonable fire reaction and resistance
