The Middle Ground for Medium Insulation Needs
The 40mm Thermal Board fills an important gap in our product lineup. Some projects find 30mm not thick enough. Others find 50mm too thick. The 40mm thickness is just right. Our Luckyfoam 40mm Thermal Board provides stronger insulation than 30mm. It saves more space than 50mm. It uses less material than 50mm. This board works well for interior wall insulation. It works well for floor soundproofing and insulation. It works well for roof insulation layers. We have been making XPS boards since 2003. We are one of the earliest XPS manufacturers in Southern Zhejiang. Our factory covers 15,000 square meters. We have three production lines. We produce 50,000 cubic meters per month. Our annual output exceeds 300,000 cubic meters.
Data You Can Depend On
The 40mm Thermal Board measures 1800 by 600 mm. The thickness is fixed at 40mm. The compressive strength is 200 kPa. The thermal conductivity is ≤0.034 W/(m·K). The water absorption rate is ≤1.5%. The dimensional stability is ≤1.5% after 48 hours at 70°C. The density is 25 to 32 kg/m³. The standard color is blue. We can also customize yellow, pink, and white. We hold ISO 9001 and ISO 14001 certifications. We are a green building materials enterprise. We have partnered with Manridge Group for years. We have supplied to the Samsung project in Xi'an. We have supplied to the SK Hynix project in Wuxi. We have supplied to the BOE project in Chongqing. Our 40mm Thermal Board performed well in these demanding projects.
Used in Many Different Applications
The 40mm board has many applications. We supplied it to Wenzhou International Electromechanical City. We supplied it to some cold storage ground insulation projects. We supplied it to some basement moisture-proof and insulation projects. Customers choose this thickness for its good cost-performance ratio. It insulates better than thinner boards. It costs less than thicker boards. We have 40mm boards in stock. We ship in 7 to 10 days. We offer a one-year warranty against non-human damage. We support mixed orders. We support OEM. We support EXW, FOB, and DDP terms. We accept RMB and USD payments.
