Superior Thermal Insulation and Energy Savings. PUF panels’ polyurethane foam layer maintains a constant interior temperature all year round. This contributes to reducing the amount of energy used for heating and cooling, which can result in yearly energy bill savings of up to 50%.

Insulated metal panels, or IMPs, are frequently referred to as sandwich panels due to their structure: a layer of foam insulation nestled between two metal sheets.

What is the difference between PIR and PU sandwich panels?

One of the major difference between PU and PIR sandwich panels is the fire/flame resistance property. PU foam is known has limited fire resistance and PU sandwich panel is normally produced with B2 and B3 fire classification. Whereas, PIR not only slows down the spreading of flames but also lowers smoke emission.

Portable structures: Sandwich panels are used to create portable structures such as temporary offices, shelters, and exhibition stands. They can be easily transported and assembled, making them ideal for use in outdoor events and construction sites.
