Handan Donghong Fiberglass & Color Steel Manufacturing Co., Ltd. is one of the leading manufacturers and suppliers of pu edge sealing rockwool roof panel in China. If you're going to wholesale cheap pu edge sealing rockwool roof panel made in China, welcome to get quotation from our factory. All customized products are with high quality and competitive price.
Product Description
The panel features a steel face and back (0.4–0.8mm), a high-density rockwool core (≥120 kg/m³, Class A), and rigid PU edge sealing. During production, the rockwool fibers are oriented vertically through a 90-degree rotation process, significantly improving compressive strength. The PU edge sealing enhances edge density and nail-holding capacity while effectively preventing thermal bridges.

Product Advantages
PU Edge Sealing Rockwool Roof Panel offers outstanding fire safety with its Class A non-combustible core. Its low thermal conductivity and PU edge sealing reduce heat loss and improve energy efficiency by approximately 15% compared to standard rockwool panels. The PU edge has high hydrophobicity (≥98%), preventing moisture penetration and condensation. Thanks to the 90-degree fiber orientation, compressive strength is increased by 50%, while edge nail-holding capacity is enhanced by 2–4 times. The panel is non-toxic, eco-friendly, lightweight, and easy to install.
Main Applications
PU Edge Sealing Rockwool Roof Panel is widely used in industrial plants and steel structure buildings, providing reliable insulation and fire protection. It is also ideal for cold storage facilities requiring strict temperature control. In addition, the panel is commonly installed in stadiums, exhibition centers, airports, and railway stations, where large-span roofs and sound insulation are essential. Agricultural greenhouses and clean rooms also benefit from its durability and energy efficiency.
FAQ
Q1: What thickness should I choose?
A1: For cold storage, 100–150mm is recommended. For standard industrial roofs in mild climates, 50–75mm is sufficient. Thicker panels provide better insulation.
Q2: Is the panel truly waterproof?
A2: Yes. The PU edge sealing has high hydrophobicity (≥98%) and prevents moisture from entering the rockwool core. The concealed clip connection system further ensures excellent water resistance.
