New Ancon A1-25/14 Non-Combustible Clip Delivers Easier Installation Without Compromise

Introducing the third non‑combustible clip in the range: the Ancon A1‑25/14 Insulation Retaining Clip. This new A1-rated, non-combustible clip has been specifically designed for use with Ancon 25/14 channel restraint system. 

Engineered from high‑tensile, A1-rated stainless spring steel, the A1-25/14 clip provides specifiers and contractors with a robust, fire-safe alternative for cavity wall systems. It supports compliance with the latest Building Regulations Approved Document B (ADB), which requires non‑combustible components in certain building applications.  

Offering excellent corrosion resistance and a design life of 60 years, the A1-25/14 clip is engineered for long-term performance. 

Developed in response to customer demand for a non-combustible insulation retaining solution that eliminates the need for drilling and fixing separate components, such as a DHM insulation retainer or similar, the A1-25/14 clip simply snaps onto the Ancon 25/14 channel for fast and efficient installation. Smooth, rounded edges help improve installer safety while ensuring reliable insulation retention. 

Key Features and Benefits 

• A1-rated non-combustible performance for enhanced fire safety.
• High-strength stainless steel design with excellent corrosion resistance and a 60-year design life.
• Quick and simple installation, developed for use with the Ancon 25/14 Channel Restraint System, extending its capability and application range.
• Reduces drilling and typically removes the need for separate insulation retainers, helping speed up installation and improve thermal performance.
