Quench is a pre-fitted fire-stopping system that removes the need for fire-stopping on-site.

Firstly, to answer the question: What is fire stopping?

What is fire stopping?

Fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly.

Firestops are designed to maintain the fire-resistance rating of a wall or floor assembly intended to impede the spread of fire and smoke

On doorsets, this is typically mastic, a rockwool type insulation that’s fitted, or a fire foam.

The problematic part with these is you need to use the fire-stopping element that has been specifically tested with that product.

Quite often these fire-stopping products come only fire-tested for a very small range of different situations and products. This then leads to incorrect fire-stopping products, which causes a fire risk.

At Selo, our WHY is to simplify complex and bespoke building methods and we wanted to do away with the fire risk and save the installer time and money.

Thus, Quench was born.


Quench is a trademarked and patented system where the system is pre-fitted to the door frame. The doorset can then be installed and no further fire-stopping or work is required.

The doorset comes with a label and inspection hole that shows Quench has been fitted.

This guarantees the fire rating, and you don’t have to worry about whether the correct fire stopping has been used, giving you complete peace of mind.
