Fire protection pipe wrap K-flex K-FIRE PIPE WRAP 110 mm – firestop insulation sleeve

K-flex K-FIRE PIPE WRAP 110 mm is a flexible fire protection sleeve designed to provide passive firestopping for pipes of approximately 110 mm diameter. The sleeve is intended for installation around pipe penetrations in walls and floors to limit the spread of fire and smoke and to help maintain compartmentation in commercial and residential buildings where certified firestop barriers are required.

Advantages

This fire protection pipe wrap is flexible and conforms to the pipe surface for a tight fit that reduces gaps. It is designed for ease of installation around existing services and through penetrations without the need for extensive modification of the surrounding structure. The material properties provide thermal resistance and intumescent action to help seal the penetration under fire exposure, helping to maintain the integrity of fire-resisting constructions.

Suitable for

• Passive firestopping of single pipes with nominal diameter around 110 mm
• Wall and floor penetrations in commercial and residential buildings
• Retrofit installations around existing services
• Applications requiring certified firestop barriers and compartmentation

Key specifications

• Nominal pipe diameter compatibility: 110 mm
• Product form: flexible sleeve/wrap for pipe penetrations
• Function: passive firestopping / fire protection
• Installation location: around pipes in walls and floors
• Performance characteristic: intumescent/thermal sealing action under fire exposure

How to use

Measure the outside diameter of the pipe and confirm compatibility with the 110 mm sleeve. Slide the K-FIRE PIPE WRAP around the pipe so that the sleeve fully covers the penetration opening; in retrofit situations open the sleeve along its split and wrap it around the installed service. Position the wrap centrally within the wall or floor opening so that it aligns with the construction thickness. Fix the sleeve to the substrate or pipe as specified by the manufacturer's instructions, ensuring there are no large gaps between the sleeve and the surrounding structure. Complete any additional sealing or support works required by the firestop system design.

Usage recommendations

Use this sleeve as part of a full firestop system that matches the building’s fire safety requirements and certified installation details. Always follow local regulations and the manufacturer's installation guidance. For penetrations with multiple services, changes in pipe material, or for specific fire-resistance ratings, consult the system documentation or a firestopping professional to confirm suitable details and achieve certified performance.
