Advanced panels designed with a focus on a clean environment.

Our urethane insulation panels are advanced panels that are ideal for creating a clean environment, equipped with high insulation properties and excellent functionality. The greatest strength of this product lies in the rigid urethane foam used as the core material. With an extremely low thermal conductivity, it exhibits high insulation effectiveness and maintains the set room temperature with high precision. Furthermore, by adopting a structure with a convex-concave fitting method that firmly connects the panels, it ensures reliable airtightness. It also excels in moisture resistance, waterproofing, and earthquake resistance, effectively protecting the indoor space from external environmental changes. This rational structure is highly workable on-site and easy to assemble, contributing to a significant reduction in construction time. The surface material uses Galvalume steel sheets that are durable and corrosion-resistant, and it comes standard with antibacterial coating, making it safe for use in places where hygiene management is required. Thanks to the factory's advanced manufacturing technology, it can flexibly accommodate various shape processing, such as openings for windows and round holes for piping. This reduces processing effort on-site and achieves a high-quality space with high precision. It is a reliable original panel widely applicable from commercial to personal products.
