China Rock Wool Insulation Board Manufacturer

Haochen Insulation is a professional China rock wool board manufacturer based in Langfang, Hebei Province. We are a large-scale physical rock wool products factory integrating R&D, production, sales and wholesale. Our main products cover a full range of thermal and fire insulation materials including external wall rock wool boards, thermal insulation rock wool boards, rock wool slabs for curtain walls, aluminium foil faced rock wool boards, rock wool strips and composite rock wool panels. Our products serve various domestic construction, decoration and industrial insulation projects, and have been exported overseas for years. We are a reliable original production base for engineering purchasers and building material wholesalers at home and abroad.

Video Description: This is on-site factory footage of Haochen Insulation. It shows the whole process of rock wool board production line, manufacturing technology, finished goods stockpiling and loading delivery. It intuitively demonstrates our standardised production capacity, stable output and formal production procedures, offering overseas and domestic clients authentic reference of our factory strength.

As an authentic original manufacturer, we fully understand the core concerns of engineering and overseas buyers: product quality, stable supply, cost performance and after-sales support. Haochen Insulation owns standardised workshops and complete automatic production lines. All products are manufactured in-house without OEM or brand outsourcing. Every procedure, from raw material screening, high-temperature melting, high-speed fibre spinning, curing and forming, to cutting, packing and loading, is strictly controlled. We eliminate defective goods from the source to guarantee consistent performance and qualified specifications for every batch of rock wool boards, complying with domestic and international construction acceptance standards.

Premium products rely on premium raw materials. We adopt natural ores such as basalt and diabase as base materials, with no waste admixture, no asbestos and no impurities. The finished rock wool products achieve A1 non-combustible fire classification, and feature outstanding thermal insulation, sound absorption, water repellency, moisture resistance and weathering resistance. They are suitable for most projects including building thermal insulation, fire & sound insulation, equipment heat preservation and steel structure fire protection.

External wall rock wool boards and ordinary thermal insulation rock wool boards are our flagship products with the largest consumption in construction projects. Two fibre orientations are available: horizontal fibre and vertical fibre, all treated for water repellency. Density ranges from 80kg/m³ to 200kg/m³ with complete thickness options. Custom cutting for special sizes is supported. The boards feature good forming, high hardness and strong compression resistance. They resist water absorption, dampness, pulverisation and peeling under long-term outdoor exposure, perfectly fitting thin-coat external insulation systems for high-rise buildings with excellent wind resistance and weather stability for engineering applications.

To meet strict construction requirements of high-rise buildings and curtain wall projects, we specially produce dedicated rock wool slabs for curtain walls. This series has high density, compact fibres, great compressive strength and superior fire retardancy. Widely used for curtain wall fire stopping, floor fire barrier strips and facade fire insulation systems, they are designated thermal & fire insulation materials for large curtain wall and high-end building projects.

For applications requiring moisture proofing, heat insulation and anti-condensation such as ventilation duct insulation, we supply aluminium foil faced rock wool boards. A thick aluminium foil layer is bonded onto the board surface, bringing heat reflection, gas barrier, moisture resistance, corrosion and dust resistance. It improves overall insulation performance and keeps neat construction surfaces, widely used for factory equipment insulation, roof insulation, pipe insulation and indoor moisture-proof insulation.

We also manufacture supporting rock wool strips and composite rock wool panels. Rock wool strips feature standard dimensions and uniform dense fibres, commonly used for building fire barrier strips, fire filling around door and window openings and gap sealing with reliable fire stopping performance. Composite rock wool panels come with pre-finished surface layers, featuring good integrity and fast installation to greatly shorten construction time, ideal for rapid-build integrated insulation projects.

Benefiting from our original factory status, all goods are supplied directly from the plant without markup by intermediate dealers. Factory prices are available for bulk engineering orders, distributor stock replenishment, small construction sites and scattered home improvement purchases. We maintain large stock all year round with full specifications and fast delivery to avoid delays to construction schedules. Both small and bulk orders from home and overseas are accepted steadily.

With years of experience in this sector, Haochen Insulation always takes quality and integrity as our foundation. We refuse falsely marked parameters and low-grade cut-corner products, and focus on supplying high-quality, cost-effective rock wool insulation products. Whether you are a domestic project buyer or overseas business partner, feel free to contact Haochen Insulation for customisation, quotation, product parameters and engineering solution consultation. We provide one-stop supporting service for insulation materials.
