Polyurethane sandwich panel is a highly efficient and energy-saving building envelope material. Also known as PU panels or anti-leakage sandwich roof panels, it is a new type of energy-saving board advocated for modern construction.
Lightweight & Aesthetic: Generally 10 kg/m2-14 kg/m2, equivalent to 1/30 of a light wall, requiring no surface decoration.
High Strength: Excellent stiffness and shock resistance. Generally, buildings using these panels do not require traditional beams and columns.
Superior Insulation: 35 mm thick panel provides thermal performance equivalent to an 1130 mm red brick wall.
Rapid Construction: Prefabricated assembly shortens construction periods by more than 40%.
Fire Safety: Class B combustion performance. Forms a "Graphite Foam" layer under fire to protect the internal structure.
Thermal Stability: Rigid foam polyurethane remains stable up to 120 °C, significantly higher than polystyrene (70 °C), preventing secondary foaming and cracking.
Combustion Principle: As a thermosetting material, PU forms a carbonized layer that blocks heat and oxygen. Unlike thermoplastic materials, it does not melt or drip, preventing flashover accidents.
Application Versatility: Can be sprayed, poured, or factory-foamed, offering more diverse application fields than molded alternatives.
Used extensively in large industrial plants, cold storages, garages, mobile houses, exhibition halls, gymnasiums, shopping centers, airports, power plants, villas, and hospitals.
Frequently Asked Questions
What is the fire rating of these panels?
The panels feature Class B combustion performance, with rigid foam forming a protective carbonization layer when exposed to flames.
What temperature range can they withstand?
They are designed to operate efficiently in environments ranging from -45 to 50 degrees Celsius.
How thick are the sandwich panels?
We provide a specification range from 50mm up to 250mm depending on your insulation requirements.
Why choose Polyurethane over Polystyrene?
Polyurethane offers higher thermal stability (up to 120°C), better fire resistance as a thermosetting material, and superior insulation thickness-to-performance ratio.
Are the panels customizable?
Yes, the panels can be customized to meet specific project requirements for construction and insulation.
What is the standard delivery time?
Typically, production and delivery take approximately 10 days after the receipt of the advanced payment.
