LONGER Insulation Integral Board with Permanent Formwork (Focus on Fire Safety & Cost-Saving)

I. Product Introduction

LONGER Insulation Integral Board with Permanent Formwork is a high-performance, cost-effective external wall building material that integratespermanent formwork, thermal insulation and Class A fire resistance — its core advantages lie in superior fire safety, significant construction period shortening and substantial cost reduction, making it a game-changer in modern building construction. Strictly compliant with the Jiangsu Provincial Engineering Construction Enterprise Technical Standard 《Application Technical Specification for JN Composite Insulation Formwork Cast-in-place Concrete External Wall External Insulation System》 (Q/320322 JN001-2024, Record No. 320322-R217-2024), this product completely replaces traditional external wall wooden formwork, eliminating the drawbacks of wooden formwork such as easy deformation, high损耗 (loss), and non-reusability, while integrating insulation function to avoid secondary insulation construction. Taking high-quality Extruded Polystyrene Board (XPS) or Flame-retardant Extruded Polystyrene Board (SXPS) as the core insulation layer, it is compounded with inner surface base coat mortar (with alkali-resistant glass fiber mesh cloth) and outer surface polystyrene particle insulation mortar, precision-manufactured through advanced composite technology. Class A fire resistance (the highest non-combustible grade for building materials) is its standout feature: it undergoes 30-minute continuous fire test with no open flame combustion or flame spread, effectively curbing fire propagation, eliminating potential fire hazards, and fully meeting national and industrial fire protection standards[3]. In terms of construction efficiency and cost control, the integrated design of formwork and insulation simplifies procedures, shortens the construction period by 30%-40% compared with traditional processes, reduces labor input and material waste, and lowers overall construction costs by 15%-25%. During construction, it can be used as external formwork (Type I, permanent formwork process) or placed inside external formwork (Type II, large formwork built-in process); after pouring, it is firmly connected to the concrete structure via pre-embedded anchors to serve as a permanent insulation layer. With excellent mechanical properties, weather resistance, Class A fire safety, and remarkable cost-saving effects, it creates energy-saving, durable, safe and economical external wall projects, fully meeting the needs of green and efficient building development.
