Glostar 50-150mm Thickness Rockwool PU Sandwich Panel for Metal Wall Cladding System
Glostar can provide high quality 50-150mm Thickness Rockwool PU Sandwich Panel for Metal Wall Cladding System. The Metal-faced insulated sandwich panels are connected to the purlin substructure via hidden fasteners within the tongue-and-groove joints, together forming the building envelope; whether installed horizontally or vertically, the tongue-and-groove design is key to ensuring watertightness, airtightness, and wind resistance.

Product Overview
High-performance composite wall panels designed specifically for industrial buildings
Glostar Rock Wool + PU Composite Sandwich Wall Panels are constructed using high-quality color-coated steel sheets and a high-density, water-repellent rock wool core. High-density rigid polyurethane foam is injected into the tongue-and-groove joints on both sides, and the panels are formed through high-pressure foaming and curing combined with a 90° automatic dense rock wool packing process. Offering excellent thermal insulation, Class A fire resistance, and waterproof durability, these panels are easy to install and feature an elegant appearance, making them one of the most widely used cladding system materials in industrial steel structure buildings.
Key Advantages
Six Key Technical Advantages
01 / FIRE SAFETY Class A Fire RatingIt meets the highest Class A fire resistance rating, significantly enhancing the overall fire resistance of steel structures and complying with the world’s most stringent building safety codes. |
02 / THERMAL Exceptional Thermal InsulationDensity of Rockwool Core Material ≥120kg/m³，PU foam is injected into both sides of the tongue-and-groove joints to eliminate thermal bridges, prevent moisture penetration that could compromise insulation performance, and ensure long-lasting durability. |
03 / WATERPROOF Airtight and waterproof sealThe tongue-and-groove joints are filled with rigid polyurethane foam on both sides, effectively blocking heat transfer and preventing water infiltration, thereby achieving a permanent airtight and watertight seal. |
04 / Corrosion-resistance Corrosion Resistance PerformanceThe leachate from the rock wool exhibits a weakly alkaline pH; it is non-corrosive to steel plates and other structural components, thereby ensuring long-term performance and enhanced structural stability. |
05 / INSTALLATION Precise and Quick InstallationThe ultra-long, precision dual-track control molding process ensures minimal dimensional tolerances and precise tongue-and-groove fits, significantly reducing on-site installation time and lowering construction costs. |
06 / ECO Environmentally FriendlyUtilizing the DCMA Smart Production Line, we adhere to high-quality standards and comply with international green building and energy conservation and emissions reduction requirements. |
