Rock wool sandwich panel with PU edge

Glostar IW 50/75/100/150mm Rock wool sandwich panels with PU edges feature a high-density rock wool core and steel facings. Specially designed with polyurethane (PU) edge sealing, these panels offer enhanced edge protection and improve the overall thermal insulation performance of the panel system.

Compared to conventional rock wool sandwich panels, the PU edge-sealing design adds an insulating layer at the panel joints, helping to minimise heat transfer through the edges.

This product is suitable for industrial plants, warehouses, pharmaceutical facilities, food processing plants, cleanrooms, and other thermally insulated building systems

A1 Fire Resistant Rock Wool Core

The high-density rock wool core provides excellent fire resistance and is suitable for projects with strict fire safety requirements.

PU Edge Sealing

Polyurethane is applied to the panel edges to provide additional edge protection and improve the insulation performance around panel joints.

Excellent Thermal Insulation

The combination of rock wool insulation and PU edge sealing helps reduce heat transfer through the panel system.

Strong Structural Performance

The sandwich panel structure combines steel facings with a rigid insulation core to provide reliable strength for wall applications.

Sound Insulation

The rock wool core also provides good acoustic insulation, helping reduce noise transmission in industrial and commercial buildings.

Customizable

Panel thickness, steel thickness, surface coating, color, length and other specifications can be customized according to project requirements.

1. Q: What is the core advantage of your PU-edged rock wool/glass wool panels compared to standard rock wool panels?

A:Our unique design combines the best of both materials. The mineral wool core provides superior fire resistance (typically Class A)and sound absorption. The polyurethane (PU) edge seal adds exceptional airtightness and water resistance, prevents moisture from entering the core, enhances structural strength at the joints, and significantly improves overall thermal efficiency by eliminating thermal bridges at the edges. This extends the panel's lifespan and durability.

2. Q: How does the "cavity and tongue-and-groove" design specifically improve performance?

A:This European-standard design is key to our panel's high performance. It ensures a precise, tight fit during installation, creating a continuous barrier. This directly results in superior airtightness (reducing energy loss from air leakage) and watertightness (preventing water infiltration), leading to a more stable indoor environment, lower energy costs, and protection of the building structure.

3. Q: What are the primary fire safety and thermal insulation ratings?

A:The panels leverage the non-combustible mineral wool core, providing high fire resistance (typically meeting Class A1/A2 standards per EN 13501-1). The PU edge and excellent joint seal contribute to overall system integrity under fire. Thermally, the low-conductivity mineral wool core offers strong insulation, and the sealed joints minimize heat loss. We provide specific fire test reports and U-value/R-value calculations for each panel configuration.

4. Q: Is installation more complex than with standard panels?

A:Not at all. The integrated tongue-and-groove system is designed for easy and fast installation. The interlocking mechanism guides panels into place, ensuring proper alignment and a seamless appearance. It simplifies the process, reduces installation time, and guarantees the performance of the joints. We provide detailed installation manuals and video guides.

5. Q: What makes these panels suitable for long-term outdoor use in varied climates?

A: Three key factors: 1) Material: High-quality, weather-resistant coated metal skins (e.g., PVDF/HDP). 2) Core & Seal:The hydrophobic mineral wool core and the water-resistant PU edge seal prevent moisture absorption and retention. 3) Design:The sealed joint system protects against driving rain and air penetration. This combination ensures compliance with stringent weather resistance standards globally.

6. Q: Can you customize the length, thickness, and color?

A: Yes, we offer extensive customization. We can produce panels in various lengths to suit your project layout, in different thicknesses to meet specific thermal or acoustic requirements, and in a wide range of colors (standard RAL colors or custom-matched). Please provide your project specifications for a detailed quote.

7. Q: What is the minimum order quantity (MOQ) and typical delivery time for export?

A:Our standard MOQ for export orders is typically one 20-foot or 40-foot container. Delivery time depends on order quantity and customization level, but generally ranges from 3 to 5 weeks after final confirmation. We offer FOB, CIF, or other agreed Incoterms and ensure secure, wooden-crate packaging for ocean freight.

8. Q: Do you provide technical support and documentation for international projects?

A:Absolutely. We provide a comprehensive technical dossier including product datasheets, material specifications, fire & thermal test certificates, CAD details, and installation guides. For large projects, we offer dedicated remote technical support and can arrange for pre-shipment inspection if required.
