Wall Sandwich Panel PUR/PIR

These PUR/PIR wall sandwich panels are highly efficient heat insulating wall plate systems that feature excellent flexural capacity. They are specifically designed for the walls of high-end buildings.

Product advantages:
1. The polyurethane panels are connected by blind nails and have no exposed screws on their surfaces, promising beautiful and smooth appearances for the walls of buildings.
2. They feature incredible flexural capacity and excellent mechanical properties that can lower the dependence on auxiliary steel structures
3. Their excellent heat preservation performance can cut down on heating and cooling costs.
