Views:
The steel structure roof of a military airfield in Jiyuan is a key national defence project for aircraft parking and maintenance. Airfield buildings impose strict requirements on roof thermal insulation, fire safety, wind resistance, waterproof sealing and lightweight material performance. After several rounds of technical evaluation and sample comparison, lightweight mortar paper rock wool composite boards from Langfang Haochen Insulation Materials Co., Ltd were selected as the main thermal insulation material for the roof system.

III. Advantages of Selected Product
Class A1 Non-combustible, Meeting Fire Specifications for National Defence Airfields
The board uses high-density basalt rock wool as core material. It achieves Class A1 non-combustible performance with excellent fire stability and can effectively restrain flame spread, complying with fire acceptance requirements for military airfield buildings.
Mortar Paper Composite Structure, Moisture Sealing for Improved Airtightness & Waterproofing
Special mortar paper is bonded onto the surface of rock wool substrate to seal gaps between rock wool fibres. It effectively blocks moisture ingress, reduces thermal bridge loss and improves overall roof airtightness and waterproofing, suited to harsh outdoor conditions at open airfields including strong wind, rainfall and ultraviolet radiation.
Lightweight and High Strength, Suitable for Large-span Steel Structure Roofs
The 140kg/m³ high-density rock wool core delivers stable thermal insulation. The lightweight board greatly reduces the load of large-span steel roofs. It features good overall rigidity and outstanding wind pressure resistance to withstand extreme loads from strong wind, rain and snow.
Factory Integrated Pre-composite Board, Greatly Shortening Roof Construction Period
Integrated composite forming at factory delivers flat, neat panels with stable performance. Standard modular dimensions allow easy on-site cutting and laying, simplifying roof insulation procedures and reducing secondary on-site work to speed up construction of the airfield steel roof.
IV. Highlights of Project Cooperation
✅ As the original manufacturer, Haochen strictly controls rock wool fibre uniformity, board density, thickness and mortar paper bonding quality. Complete qualification documents and third-party test reports are provided for every batch to guarantee project acceptance;
✅ Special batch production and logistics scheduling arranged according to the airfield construction schedule to ensure steady on-time delivery and meet key project milestones;
✅ Professional on-site technical support available to guide board laying, joint treatment and optimise roof insulation construction solutions;
✅ Full set of product technical documents and acceptance materials supplied to support fire inspection, final completion acceptance and document filing.
V. Project Summary
Two specifications of Haochen lightweight mortar paper rock wool composite boards were adopted for the steel structure roof project of this military airfield in Jiyuan. All technical parameters satisfy design standards and national defence engineering codes. Its excellent fire resistance, thermal insulation, wind resistance and waterproof stability have gained unanimous recognition from the main contractor and supervision team. This project confirms that Haochen mortar paper rock wool composite boards are widely applicable for high-standard insulation works such as military airfields, national defence infrastructure and large steel structure buildings, serving as a preferred reliable lightweight fire-resistant insulation material for large-span roof systems.
