Product introduction
PU edges rockwool sandwich panels are advanced composite building panels that integrate a rockwool core for exceptional fire resistance and thermal insulation, with polyurethane (PU) reinforced edges to enhance sealing, moisture barrier properties, and structural durability.

|
20mm Plug-in |
The socket incorporates precision fastening grooves for accurate and efficient installation. |
|
|
10mm Plug-in |
The insulated core of the socket maintains tight connections, effectively blocking thermal conduction. |
|
|
Seamless Plug-in |
The socket exterior features an air chamber structure, achieving equal-pressure rain screen functionality to prevent water infiltration. |
Product advantages
☆Fireproof performance
The rock wool core material is a non-combustible material with an ultra-high 1000℃ fusion temperature, which can effectively block the flame in a fire and minimize the fire loss.
☆Insulation and energy saving
Rock wool has a low thermal conductivity (0043w/m·k) and good thermal insulation performance. Excellent node design ensures sealing performance and thermal insulation effect.
☆Good sound insulation
The sound insulation volume is ≥ 30DB, which effectively reduces the interference of external noise.
☆Watertightness/airtightness
Using polyurethane edge sealing, the tongue and groove are flat and can effectively prevent water from entering; the joints of the board are sealed inside to maintain good airtightness.
☆Sturdy and durable
Use high-quality rock wool materials or glass wool, with high water-reliability and long-lasting stability.
