A PUF sandwich panel is a type of building material made from polyurethane foam (PUF) sandwiched between two layers of metal or other materials. These panels are commonly used in construction for walls, roofs, and floors due to their insulation properties and strength.

The polyurethane foam core provides excellent thermal insulation, which can help reduce energy costs for heating and cooling. The metal or other material layers on either side of the foam provide structural support and protection against weather, moisture, and other external factors.

PUF sandwich panels are lightweight, easy to install, and require little maintenance. They are also durable and can withstand extreme temperatures, making them ideal for use in both cold and hot climates.

Overall, PUF sandwich panels are a popular choice for construction projects due to their insulation properties, strength, and ease of use.
