Glazing Liners

Glazing Liners

Our fire rated glazing liners are designed to reinforce the integrity of glazed elements in fire doors and screens, forming a critical barrier between the glass and the door frame. When used in conjunction with fire-resistant glass, these liners help maintain the fire rating of the complete assembly by expanding under heat to seal gaps and limit the passage of flames, smoke, and heat.

Intumescent Protection for Glazed Openings 

Manufactured from high-performance intumescent materials, our glazing liners activate during a fire, expanding to fill the void around the glass perimeter. This ensures compliance with FD30 and FD60 rated systems and supports the overall fire containment strategy. They are suitable for use in timber, composite, and steel fire doors, and are often paired with fire rated glazing tape to deliver a complete passive fire protection solution. 

Discreet Design, Reliable Performance 

Our intumescent glazing liners are supplied in flexible strip form for easy handling and quick installation. With a discreet profile that sits neatly between the glass and the frame, they deliver protection without affecting the visual appeal of the door. Ideal for both new installations and retrofit projects, they help ensure your fire door glazing systems meet regulatory standards with long-lasting, tested performance.
