Core Joint
Core Joint is an aluminium cassette system manufactured in-house by Gordian using pre-coated aluminium.
The system is designed to provide a consistent external appearance, with clean joint lines and concealed fixings creating a uniform look across the building envelope.
- A1 non-combustible aluminium cladding system
- Tested & compliant with CWCT standards
- UL third-party product certification
- Discreet fix cassette cladding system
- Wide range of colours and finishes available
- 100% recyclable aluminium construction
Core Joint is a mechanically fixed cassette system designed for flexibility across a wide range of projects.
Manufactured using pre coated aluminium, the cassette panels are fixed back to a supporting carrier system, with concealed fixings within the joint detail. This creates a clean, uninterrupted surface while maintaining a drained and ventilated design that protects the underlying structure and supports long-term durability.
Manufactured in different panel sizes to suit the building, Core Joint is suitable for commercial, residential and public sector projects, making it adaptable for both new build and refurbishment applications.
Product Details
-
UL (Underwriters Laboratories) is a globally recognised, UKAS-accredited organisation providing independent testing, certification and auditing services across the construction industry.
Core systems have been independently assessed by UL and meet the requirements of the UL Mark ‘Performance of Curtain Walling and Cladding and Rainscreen Cladding Support Systems’ certification scheme. The UL Mark is recognised by the NHBC as an accepted product certification route alongside organisations such as the BBA and Kiwa within NHBC Technical Guidance 2.1/01.
-
Core systems are manufactured using A1-rated aluminium components, achieving the highest classification for non-combustibility under BS EN 13501-1.
This classification supports compliance across modern façade applications and aligns with current regulatory requirements for external wall construction. The use of A1 aluminium provides confidence in fire performance while maintaining durability and long-term façade stability.
-
Core systems have been tested in accordance with CWCT standards to demonstrate façade performance under a range of environmental conditions.
Testing covers air permeability, water penetration, wind resistance and impact performance, providing assurance of long-term durability and reliable system behaviour. This supports consistent performance across commercial, residential and public sector applications.
-
An Environmental Product Declaration (EPD) provides transparent information on the environmental impact of a material across its lifecycle, based on independently verified data in accordance with recognised standards.
Luxeclad aluminium used within Core systems is supported by an EPD, providing clear information on material sourcing, manufacturing and environmental performance. This supports informed specification and contributes to wider project sustainability requirements, including BREEAM and other environmental assessment frameworks.
