Discover Superior Roof Insulation: B2 Grade Fire-Retardant Polyurethane Foam Board

In the realm of modern construction, energy efficiency and fire safety are paramount. For architects, contractors, and builders seeking a reliable, high-performance insulation solution, the answer lies in specialized materials. Today, we focus on a standout product that combines excellent thermal properties with crucial fire safety features: the B2 Grade Fire-Retardant Polyurethane Foam Board from Langfang.

Engineered for excellence, this polyurethane roof insulation board is designed specifically for XPS exterior wall insulation systems. Its core strength lies in the material: high-quality polyurethane formed into a microcellular structure. This unique morphology is key to its impressive thermal performance, boasting a low thermal conductivity of just 0.035 W/(m·K) at ambient temperature. This means it provides exceptional thermal resistance, significantly reducing heat transfer and helping to maintain consistent indoor temperatures, which translates to lower energy costs.

Beyond insulation, safety is a non-negotiable feature. This board is classified as B2 Grade for fire retardancy. In practical terms, this means the material is self-extinguishing; when the source of flame is removed, it will cease to burn. This flame-out self-extinguish property adds a critical layer of protection to buildings, making it a responsible choice for various commercial and industrial applications.

The mechanical properties further solidify its reliability for roofing and wall applications. It offers a balanced strength profile with both compressive and flexural strength at 177 kPa, ensuring it can withstand typical loads and stresses. The board also maintains performance under strain, with a low-temperature flexure of ≤9% and an elongation at break of 8%. With a standard size of 1200*600*70mm and a rectangular shape, it is designed for efficient installation and coverage.

Manufactured by Xin Zhi Xing Yuan in Langfang, a hub for quality polyurethane products, this insulation board (Item#: YC2023040603) is a testament to focused expertise. It is suitable for use in environments with temperatures up to 200°C. As a versatile component, it is also available for custom fire-resistant (OEM) orders, allowing projects to specify requirements precisely.

For professionals looking to enhance their project's thermal efficiency and fire safety compliance, this B2 Grade Polyurethane Foam Board presents a compelling solution. It effectively fulfills the dual function of insulation and fire protection. Please note that pricing is exclusive of taxes and shipping, which are calculated based on order volume.
