Product Details
Polyurethane sealing rockwool sandwich panels for roof are a preferred material for modern building envelope systems, integrating high-efficiency thermal insulation, superior fire resistance, and durable sealing performance. This product employs a unique “sandwich” structure, using high-quality rock wool as the core material, with high-strength color-coated steel sheets laminated on both sides. Through an advanced continuous production line, the edges of the panels are integrally sealed with polyurethane material.
Core Characteristics and Advantages
Superior Thermal Insulation Performance: Rock wool core material has an extremely low thermal conductivity, effectively blocking heat transfer, significantly reducing building energy consumption, and meeting the stringent requirements of green building and energy-saving design.
Top-Tier Fire Safety Rating: Rock wool is an A1-class non-combustible material that does not produce molten drips or toxic fumes when exposed to fire. Combined with polyurethane sealing edges, it effectively prevents the spread of fire and smoke, providing a crucial fire barrier for the building.
Durable Waterproofing and Airtightness: The core innovation lies in the polyurethane sealing process at the four edges. It completely eliminates the potential for cold bridging, water seepage, and air leakage at the seams of traditional rock wool sandwich panels, forming a continuous and complete sealing system. Significantly improves the overall water tightness and air tightness of the roof, ensuring no leakage during long-term use.
Strong and durable, with a highly efficient structure: The upper and lower metal panels and dense rock wool core are bonded together with a high-strength adhesive to form an integrated load-bearing structure, possessing excellent compressive and bending strength and rigidity. Polyurethane sealing edges further enhance the integrity of the panels, resulting in a flat, aesthetically pleasing roof with strong load-bearing capacity after installation.
Easy installation, economical and efficient: Standard panel design allows for flexible and quick installation. Polyurethane sealing edges ensure a tighter and more reliable connection between panels, simplifying joint treatment, improving construction efficiency and project quality, effectively shortening the construction period, and reducing overall costs.
