How Quelfire Supports M&E Contractors

We Understand Your Challenges

As an M&E contractor, firestopping may not be your primary trade, but it often falls within your scope of work. Whether sealing around pipes, ducts, or electrical services, you’re expected to integrate firestopping into wider installations. This adds complexity, as each service type requires its own specific solution, and you still carry the responsibility of ensuring compliance with building regulations and tested evidence.

  • Multiple Service Types

    Pipes, ducts, and cables all need to be sealed differently, with different tested systems. Knowing which product is correct for each penetration can be confusing, especially when you’re balancing this alongside your core trade responsibilities.

  • Late Consideration of Firestopping

    Firestopping is often left until the later stages of a project. By the time you come to install, some services and openings are already in place, which can make applying solutions exactly as designed more difficult and time-consuming.

  • Lack of Awareness or Training

    Because firestopping isn’t always your main focus, your teams may not have the same level of knowledge or experience as a specialist contractor. Without the right awareness or training, there’s a higher risk of products being installed incorrectly - or missed altogether.

  • "I think I can speak for the whole of Pyrotect both Sales & Contracts that you and your team have certainly met our expectations and on many occasions surpassed. Whilst in a highly scrutinised and somewhat demanding industry, we thank the Quelfire Team for your level of detail, reaction times & continued support."

  • "As accredited installers, there’s a necessity for us to deal with a vast array of manufactures throughout the year. Quelfire however, have firmly stamped their position as our most trusted and frequently used manufacturer. Aside from a truly exceptional level of customer and technical support, they boast one of, if not the, broadest collection of test data available. You really get a feel that they are listening to the needs of the installer and our clients, with virtually all scenarios being met with already tested, or soon to be tested solutions."

  • "Quelfire have a wide range of tested details and scope of application, I haven't yet come across an instance where Quelfire didn't have a tested solution which another manufacturer did. The technical team is second to none and always want to help as best as they can, even if they can't offer a direct solution they are keen to offer advice to point me in the right direction. I always receive an answer to any technical query within 2 hours and the majority of the time a lot quicker. In the past 16 months I have placed numerous orders and every single one has been delivered to site the next day and undamaged."
