Brief Description:Plastic PP anchors for ETICS. 50–200mm, tough, weather & ageing resistant. Fix stone wool, EPS, XPS for wall, roof & curtain insulation. Factory bulk supply.

Haochen Insulation is a specialist manufacturer of anchoring accessories for building insulation. We supply a complete portfolio of insulation fasteners, including plastic expansion insulation fixings and one-piece insulation fixings. Suitable for a wide range of insulation applications such as external wall, internal wall, roof and curtain wall insulation works, these fixings secure stone wool boards, XPS boards, EPS boards and foam boards. They are standardised anchoring components offering broad compatibility, reliable stability and versatile use across building insulation projects.

Plastic expansion insulation fixings are the predominant fastener type for External Thermal Insulation Composite Systems (ETICS). Operating on the mechanical locking principle of the expansion sleeve, the sleeve expands automatically against the bore wall once inserted into pre-drilled holes, creating tight engagement and high pull-out resistance to prevent loosening or dislodgement after installation. Compared with conventional split-style insulation fixings, our one-piece plastic expansion insulation fixings are produced via monolithic injection moulding with no joint gaps. This delivers superior structural integrity, markedly improved tensile and breakage resistance, alongside simpler site handling and faster installation rates. The design inherently eliminates common construction defects associated with split fixings, such as loose sleeves, sliding steel pins and full assembly detachment, enhancing the overall stability of the insulation layer and raising finished project quality.

This product range is fabricated from high-toughness modified plastic, delivering consistent structural strength and excellent resistance to low temperatures, ultraviolet radiation, ageing and corrosion. Capable of enduring harsh outdoor exposure including solar irradiation, freeze-thaw cycles and weathering over extended service periods, the fixings resist embrittlement, deformation and functional failure, meeting requirements for long-term exposed anchoring on external facades. Suited to high-rise external wall insulation, internal render insulation, roof thermal insulation and curtain wall finishing schemes, they provide precise anchorage for diverse insulation boards. They mitigate frequent site issues including hollowing, lifting, displacement and delamination of insulation layers, safeguarding the structural integrity of the complete insulation system.

Haochen insulation fixings are available in a comprehensive size range, with standard lengths spanning 50mm to 200mm. Ample stock is maintained, and custom extended or special-size variants can be manufactured to order. All plastic expansion and one-piece insulation fixings are produced to engineering standards and undergo independent testing for pull-out strength, weathering performance and locking capability. They deliver ample anchoring force, secure locking and exceptional durability, suitable for small and large-scale insulation projects including residential dwellings, commercial buildings, industrial facilities, existing building refurbishment and curtain wall installations.

As a direct original manufacturer, we remove middleman mark-ups. We accommodate bulk project orders and ongoing supply contracts for building material distributors, with short lead times, competitive pricing and consistent, uniform product quality. Whether for routine internal or roof insulation works, or high-specification external facade and curtain wall insulation projects, Haochen plastic expansion anchoring fixings deliver robust, long-lasting anchoring solutions. They are the preferred auxiliary insulation accessory for main contractors and building material suppliers.
