Rockwool Insulation Wall Panel

The Element rock wool sandwich wall panel is a high-quality panel designed specifically for building envelopes. It meets Class A fire safety standards, effectively ensuring fire safety; offers sound insulation of 30 dB; and utilizes hydrophobic materials, achieving a hydrophobicity rate of 99%.

The panel features a concealed screw connection system, exceptional surface flatness, and customizable joint widths, complemented by a durable, baked-on paint finish available in various colors.

Its pure rock wool core-with a density of approximately 120 kg/m³-ensures high structural strength and long-term performance stability. Combining fire resistance, thermal insulation, sound insulation, and weather resistance, it is widely used for wall applications in industrial, commercial, and cold storage facilities.

Excellent Fire Resistance

Rockwool achieves Class A fire rating. It inhibits flame propagation and protects buildings, greatly reducing fire hazards.

Superior Sound Insulation

It delivers up to 30dB noise reduction, effectively blocking sound transmission for quieter indoor environments.

Hydrophobic & Air-tight Performance

Hydrophobic rockwool repels water. Combined with sealed panel joints, it prevents moisture penetration and ensures air tightness.

High Strength & Long Service Life

With a density of ~120 kg/m³, rockwool core has stable mechanical performance, high structural strength and long-term durability.

 

 

Benefits of Rock Wool sandwich Panels

Element PU edge sealed rockwool sandwich panel combines metal facings with 120kg/m³ rockwool core and polyurethane edge sealing. It achieves Class A1/B1 fire rating under GB8624-2012, and its core thermal conductivity λ=0.041 W/(m·K) delivers stable thermal insulation. The thermal resistance (R-value) rises with panel thickness, while the U-value decreases to cut building energy loss.

 

Available in 40–200mm thickness, 900–1000mm width, it supports color-coated steel, stainless steel or aluminum facings with multiple surface profiles. PU edge sealing solves the water absorption weakness of rockwool, forming airtight joints. It also provides 30dB noise reduction, high mechanical strength and flexible custom lengths. Ideal for factories, cold storage and commercial building envelopes.

Rockwool insualtion Panel for warehoue

It reaches Class A1/B1 fire rating complying with GB8624-2012. The rockwool core restrains flame spread and heat transfer, offering solid fire protection for industrial and cold-storage buildings.

PU sealed Rockwool panel

The 120kg/m³ rockwool core has thermal conductivity λ=0.041 W/(m·K). Higher panel thickness brings larger R-value and lower U-value, effectively reducing heat loss and cutting energy consumption.

Vertical Installation for wall panel

PU edge sealing overcomes the drawback of rockwool water absorption. Tight panel joints block moisture ingress. It achieves 30dB noise reduction to improve indoor acoustic environment.

Rockwool Sandwich Panel

Available thickness 40–200mm, width 900–1000mm. Optional facings: color-coated steel, stainless steel or aluminum with diverse surface styles. High structural strength and customizable length simplify installation.
