Brief Description:Insulation fixings for ETICS. 3-part design: nylon disc, sleeve & galvanised steel pin. High tensile strength, weather & ageing resistance, low thermal bridging. Fix stone wool, XPS, EPS on masonry & hollow brick. 8–20cm, custom lengths, factory supply.

Haochen insulation fixings, also referred to as engineering plastic expansion anchors, are dedicated mechanical anchoring components for External Thermal Insulation Composite Systems (ETICS) and indispensable core ancillary materials for contemporary building insulation works. Suitable for insulation installation on internal and external walls, roof structures and building curtain walls, these fixings securely fasten stone wool boards, XPS boards, EPS boards and other insulation panels. Compatible with a wide range of substrates including solid masonry, hollow brick and perforated blockwork, they are widely deployed across new-build and refurbishment projects such as residential dwellings, commercial buildings, industrial plants and existing housing renovation schemes.

This range of insulation fasteners is manufactured via monolithic injection moulding. Lightweight in construction with stable structural performance and balanced physical properties, they combine cost-effectiveness with simple installation procedures. No complex site operations are required, making them the preferred option for small-to-medium routine projects including ceiling insulation, internal wall insulation and temporary thermal insulation works, meeting standard fixing requirements for general building applications.

For high-spec external works, upgraded material formulations deliver markedly enhanced mechanical performance with substantial improvements in toughness, tensile load capacity and impact resistance. Boasting excellent temperature tolerance, ageing resistance, UV stability, weathering resistance and corrosion protection, the fixings withstand harsh service conditions such as prolonged solar exposure, freezing frost and seasonal temperature fluctuations. They resist cracking, embrittlement, deformation and dislodgement, maintaining consistent long-term performance to satisfy stringent requirements for high-rise facade insulation, exposed roof insulation and premium curtain wall thermal systems.

The product adopts a proven three-part assembly, precision fabricated from a nylon retaining disc, expansion locking sleeve and galvanised anti-corrosion steel pin. Operating on a mechanical expansion interlock principle, once inserted into pre-drilled substrate holes the anchor conforms closely to the bore wall, distributing load evenly and forming a firm lock. It creates a robust connection between substrate and insulation panel, mitigating common site risks such as hollowing, displacement, delamination and water ingress, thereby improving the structural integrity and service life of the insulation assembly. Furthermore, the pairing of electrically insulating nylon with galvanised steel effectively reduces thermal bridging, cutting heat loss and preserving the building’s thermal performance.

Haochen Insulation is an original manufacturer of insulation fixings. Our standard product range covers lengths from 8cm to 20cm with ample stock maintained for prompt despatch. Custom extended and special-size variants are available, with anchor selection tailored to site substrate conditions and insulation panel thickness. Every batch undergoes pre-delivery testing for pull-out strength, weather resistance and compressive performance to enforce rigorous quality control, ensuring compliant and dependable performance. Direct-from-factory supply eliminates intermediary mark-ups, delivering competitive pricing. We accommodate bulk project orders and long-term supply contracts for distributors, delivering robust, durable and cost-effective complete anchoring solutions for all types of building insulation schemes.
