75mm Rock wool Pir Sealing Sandwich Roof Panel

1 Product Parameters

2 Product Features

Propanel’s 75mm roof panel integrates a high-density rock wool core (A1 non-combustible, EN 13501-1) with PIR edge sealing, achieving 0.022W/m·K thermal conductivity for superior insulation. This dual-layer system ensures stable indoor temperatures (-40°C to +100°C) while cutting HVAC energy use by 35% versus conventional roofing. The rock wool core provides 120-minute fire resistance, meeting strict industrial safety codes, while the PIR-sealed edges block moisture ingress (water absorption <1.5%) and thermal bridging, extending service life to 40+ years.

Structural & Installation Advantages

• Load-Bearing Capacity: Supports 2.5kN/m² uniform load (tested per EN 14509) with 0.6mm galvanized steel facings (AZ150 coating).

• Quick Assembly: Lightweight 14kg/m² design enables 50% faster installation than concrete decks, reducing labor costs.

• Weatherproof Design: PU-sealed joints resist 3,000Pa wind uplift (ASTM E1592), ideal for cyclone-prone regions.

Sustainability & Compliance

• 100% recyclable rock wool core with zero VOC emissions.

• Certified to LEED v4 and BREEAM standards for green building credits.

• Backed by 30-year warranty against structural degradation.

3  Advantages of Propanel's Rock Wool 

Propanel’s rock wool PIR sealing sandwich panels outperform conventional EPS, PU, and glass wool cores across critical performance indicators. Engineered with a high-density rock wool core (≥120kg/m³) and precision-molded PIR edge sealing, this panel delivers A1-class non-combustibility (EN 13501-1) – it withstands open flames without toxic emissions, providing 120+ minutes of fire resistance for safe evacuation and rescue operations.

Thermal Performance That Endures
While rock wool's 0.038W/m·K thermal conductivity rivals glass wool and exceeds EPS, its real advantage lies in high-temperature stability. Unlike PU, which degrades above 120°C, rock wool maintains consistent insulation performance up to 1000°C – critical for industrial workshops, foundries, and fire-rated compartments. This stability reduces HVAC load fluctuations by 25% versus polyurethane in extreme environments.

Acoustic & Chemical Resilience
The panel’s fibrous structure (porosity >95%) absorbs sound waves across low-to-mid frequencies, achieving NRC 0.95 – 40% better than PU or EPS for machinery noise reduction. Chemically inert rock wool resists acid/alkali attack (pH 3-11), preventing embrittlement seen in polystyrene after 5 years of chemical exposure, extending service life to 50+ years.

Sustainable & Sealed Design
Manufactured from natural basalt/dolomite (100% recyclable, zero VOCs), the core pairs with PIR edge sealing that eliminates thermal bridging and moisture ingress (water absorption <1.5%). The integrated sealing system also blocks air leakage, improving building airtightness by 30% versus unsealed panels.

 

 

Application Versatility
Ideal for pharmaceutical cleanrooms, cold storage vestibules, data centers, and high-rise fire barriers. Propanel’s panels are certified to LEED v4, BREEAM, and ISO 14001, delivering a 35% lower carbon footprint than PU alternatives. Backed by 30-year structural warranty and 25-year thermal performance guarantee.

5 RFQS of Rock Wool Sandwich Roofing Panels with PU Sealing

1. What is a rock wool sandwich panel?
Propanel's rock wool panel bonds two steel facings to a high-density mineral wool core, delivering structural rigidity with A1 fire resistance. It provides integrated thermal/acoustic insulation for industrial and commercial buildings.

2. Why choose ROCKWOOL solutions?
Propanel's rock wool achieves A1 non-combustible rating (EN 13501-1), offering 120-minute fire integrity. It withstands 1000°C without toxic smoke, making it mandatory for hospitals, schools, and high-rise safety zones.

3. What is the difference between Rockwool and PUF panels?
Propanel Rockwool excels in fire safety (A1 class) and acoustic control (NRC 0.95), while PUF provides 0.024W/m·K ultra-insulation for cold storage. Choose Rockwool for fire-critical areas, PUF for energy-centric envelopes.

4. Is sandwich panel waterproof?
Propanel's rock wool panels feature hydrophobic treatment (<2% water absorption) with PU-sealed edges, blocking moisture penetration. Tested to EN 1027, they resist 3,000Pa wind-driven rain – ideal for humid coastal climates.

5. How long does ROCKWOOL insulation last?
Propanel rock wool panels maintain thermal performance for 50+ years (tested per ASTM C356). The inert mineral fiber resists aging, corrosion, and biological degradation, backed by a 30-year structural warranty.

5. How long does ROCKWOOL insulation last?

  Rock wool Sandwich panel has a service life of more than 50 years.
