Glostar sandwich roof panel is a next-generation roofing solution that combines structural strength, thermal efficiency, and fire safety. As a leading insulated roof panel, it is engineered with a non-combustible rock wool core and high-strength steel facings, delivering exceptional performance for industrial and commercial buildings. This sandwich roof panel is designed to replace traditional built-up roofs with a single-component system that saves time and labor.
Unlike conventional roofing materials, our sandwich roof panel provides continuous insulation without thermal bridges. Every sandwich roof panel in our production line undergoes strict quality control, ensuring consistent thickness, flatness, and edge sealing. For projects that demand an insulated roof panel with long-term durability, Glostar offers up to 200mm thickness options.
Safety is non-negotiable for any roofing application. That is why this sandwich roof panel is manufactured as an A1-class fire resistant roof panel. The rock wool core is completely non-combustible, giving the full system 1 to 4 hours of fire resistance. When you specify a fire resistant roof panel from Glostar, you meet the strictest building codes for factories, warehouses, and cold storage facilities. This fire resistant roof panel does not melt or produce toxic smoke, providing critical evacuation time in case of fire.
Every sandwich roof panel in this series passes the same fire test standards, making it a reliable fire resistant roof panel for global projects. Whether you need a 2-hour or 4-hour fire resistant roof panel, we can supply the exact configuration.
Roof leakage and heat loss are the two most common complaints from building owners. Glostar solves both with a true waterproof roof insulation panel. The panel features a specially designed lap joint with pre-applied sealant, creating a continuous watertight barrier. As a waterproof roof insulation panel, it prevents water ingress even under standing water or wind-driven rain. At the same time, this waterproof roof insulation panel maintains a thermal conductivity as low as 0.046 W/(m·K), keeping interiors warm in winter and cool in summer.
When you choose a waterproof roof insulation panel, you eliminate the need for separate waterproof membranes and insulation layers. This sandwich roof panel acts as structure, insulator, and waterproofing all in one. Contractors report that installing a waterproof roof insulation panel from Glostar is 30% faster than traditional multi-layer systems.
Modern construction schedules demand fast, predictable installation. Glostar offers a complete prefabricated roof panel system, cut to exact project lengths and delivered ready to install. Every prefabricated roof panel is manufactured in our ISO-certified facility with CNC-controlled cutting, ensuring millimeter accuracy on site. Using a prefabricated roof panel reduces on-site cutting waste, lowers labor costs, and shortens the construction period by 10% or more.
The prefabricated roof panel system includes matching trims, fasteners, and sealants – all from one supplier. When you order a prefabricated roof panel from Glostar, you receive a complete package with no missing parts. This prefabricated roof panel approach is ideal for large-scale projects like logistics centers, aircraft hangars, and exhibition halls.
No single keyword tells the full story. A true sandwich roof panel must be an insulated roof panel to save energy. It must be a fire resistant roof panel to protect lives and assets. It must be a waterproof roof insulation panel to prevent leaks and condensation. And it must be a prefabricated roof panel to meet tight construction deadlines. Glostar is the only manufacturer that designs every sandwich roof panel to fulfill all five requirements simultaneously.
