FireFly Fire Collars

October 2, 2026

Service penetrations are an essential part of modern buildings, but openings created for pipes and services can affect fire compartmentation.


Fire collars are one of the products used within passive fire protection systems to help protect pipe penetrations through fire-resisting walls and floors.


Blazeout supplies FireFly fire collars as part of our wider range of FireFly firestopping products.


What is a FireFly Fire Collar?

A fire collar is designed for use around suitable pipe penetrations where an intumescent firestopping solution is required.


When exposed to fire, intumescent materials react and expand, helping to close the opening created when combustible components within a penetration are affected by heat.


The correct collar must always be selected for the specific pipe type, diameter, construction and tested system.


Fire Collars and Compartmentation

Firestopping around service penetrations is an important part of maintaining compartmentation.


A correctly specified fire collar can form part of a tested system designed to protect pipe penetrations through fire resisting construction.


For installers, it is important to follow the manufacturer's installation requirements and use the collar within its approved application.


Whether you're working on a new construction project, refurbishment or remedial firestopping work, Blazeout can supply FireFly fire collars alongside a wide range of associated products.
