Ribbing: Various ribbing styles are available
Rabbet: TOPOLO patented rabbet joint is waterproof and convenient for the sealing and gluing of PIR panels. It can save energy and extend the lifespan of reefers, fridges, and other end products.
Jointing: The joints of TOPOLO PIR panels are free from sealing agents like brown paper and non-woven fabric. The PIR foam from two panels contacts directly, which ensures the best insulation performance.
Bonding: We have an advanced gluing system and patented equipment to support the bonding quality between PIR foam and the panel skin.
The pretreatment of corona on the panel skin also strengthens the adhesion of the skin with the foam.
