Shandong Lvran New Materials Co., Ltd. is a professional manufacturer dedicated to the R&D, production and sales of high-performance construction new materials, mainly supplying high-grade waterproof backer boards and B1 fire-retardant XPS extruded polystyrene boards. With a solid foothold in the building materials industry, we focus on product innovation and strict quality control, aiming to deliver reliable, eco-friendly and cost-effective solutions for global construction, decoration and energy-saving projects. Boasting 10 years of rich professional production experience, we own standardized workshops, automated production lines and a complete quality management system to ensure stable product output and consistent quality. Our multi-functional waterproof backer boards stand far above traditional OSB boards and gypsum boards in comprehensive performance. Integrated with excellent heat preservation, waterproofing, moisture-proofing and sound insulation capabilities, these boards solve the common defects of conventional panels such as water absorption, mildew, deformation and poor thermal insulation. Featuring simple installation and no complicated secondary processing, our products greatly streamline construction procedures and effectively shorten the overall construction cycle, helping clients cut labor and time costs significantly. Our waterproof backer boards have a wide range of application scenarios, including residential and commercial kitchens, bathrooms, basements, ceilings and wall partitions. We specially launch dedicated bathroom waterproof boards available for bulk wholesale, with complete specifications and customizable sizes to satisfy demands of engineering orders, distributors and decoration contractors. Manufactured from carefully selected premium raw materials via sophisticated processing techniques, the boards feature compact internal structure, outstanding sturdiness and long service life. Their superior waterproof performance can thoroughly block water and vapor penetration even in long-term humid environments. Every product undergoes rigorous multi-level testing before delivery, so you can enjoy fully guaranteed quality and stable long-term use. Our B1 fire-retardant XPS extruded polystyrene boards are ideal core materials for modern energy-efficient buildings. Adopting advanced high-density closed-cell foaming technology, the products form a dense and stable internal structure. This unique structure endows the boards with industry-leading thermal insulation, outstanding water repellency, great mildew resistance and permanent moisture resistance. Thanks to the stable molecular composition, the physical properties of XPS boards will not degrade under changing temperature and humidity. In addition, our XPS boards possess remarkable compression resistance and strong impact resistance, which can withstand long-term load pressure without deformation. They are widely applied to building wall insulation, roof thermal protection, floor frost heave prevention and municipal plaza pavement projects. With certified B1 fire retardant grade, the boards can effectively inhibit flame spread and enhance overall building safety. All our products comply with international environmental standards, being non-toxic, odorless and pollution-free. We always stick to customer-oriented service and sincere cooperation, looking forward to establishing long-term win-win partnerships with clients worldwide.
