Description
Description
QB50 QuelStop Ablative Coated Mineral Wool Fire Batt is a coated mineral wool board used to reinstate the fire rating of wall and floor constructions where they have been penetrated by services.
Standards & Approvals
Standards & Approvals
QuelStop Fire Batt is used to maintain the fire integrity of compartment walls or floors, typically where oversized holes have been formed for services. A single or double batt may be required depending on a number of factors and it can also be fitted as a pattress fit (or face fit) too.
QuelStop Fire Batt is always installed in conjunction with QuelStop Intumescent Acrylic Sealant which is applied to all cuts, joints and exposed edges.
Where combustible, non-combustible services and insulated services penetrate the QuelStop Fire Batt seal the following additional products may be required:
- QuelCoil Intuwrap
- QWR Fire Collar
- QRS Fire Sleeve
- QuelStop HPE Graphite Sealant
- QuelStop Intumescent Acrylic Sealant
- QIF Insulated Fire Sleeve
- QI Intufoam
For full details on the size of seals, the spacing of services, batt overlap requirements, seal details etc refer to all available documentation, installation details and the Quelfire Technical team.
QuelStop Fire Batt can be installed in many different ways. In all cases the surfaces, letterbox and services must be clean of contaminants and dust free and the batt must be installed with QuelStop Intumescent Acrylic Sealant and in conjunction with the supporting documentation provided. To give some idea of the scope of the system, some indicative installation details are:
QuelStop Fire Batt in a letterbox opening with multiple services used in conjunction with other Quelfire products including QuelStop HPE Sealant and QRS Fire Sleeves
QuelStop Fire Batt as a pattress (or face fit) installation used in conjunction with other Quelfire products including QuelCoil Intuwrap to insulated non-combustible pipes.

*Please note that custom made items can expect to have longer lead times. Next working day is typical but can depend on outside factors not controlled by Quelfire.

Firestopping Product Spotlight: QB50 Fire Batt
In this short video, Alec Purdie (Technical Manager) highlights our QB50 Fire Batt. It is made from mineral wool and coated with an ablative coating and has been tested in a number of applications and supporting construction types as discussed in this video.

Firestopping Tested Detail: Pattress Fire Batt with Overlap
We have tested a wide variety of services from bundles of PE-X pipes to CPVC sprinkler pipes and even TracPipe®. However, one of our unique features is our overlap: we tested with a minimum of 50mm on the sides and top. For those low ceilings, we have tested details with a minimum of 30mm overlap.

Firestopping Tested Detail: Single-Sided Access (QuelStop Fire Batt)
As Alec Purdie (Technical Manager) explains, there will be instances onsite where firestoppers cannot get to both sides of the supporting construction. We now have test evidence where you can install the QuelStop Fire Batt from one side only.
Frequently Asked Questions
What is Fire Batt?
What is Fire Batt?
Fire Batt is a high-density mineral wool board, coated on one or both sides with a fire-resistant sealant, designed to reinstate fire resistance in wall and floor penetrations
How does Fire Batt work?
How does Fire Batt work?
The mineral wool core provides thermal and acoustic insulation, while the ablative coating reacts to fire, creating a robust barrier that prevents flames, smoke, and heat from spreading.
Can Fire Batt be cut to size on site?
Can Fire Batt be cut to size on site?
Yes – it can be cut using a sharp knife or saw to suit the required opening, making it flexible and adaptable for different service penetrations.
Do I need to use Fire Batt with other firestopping products?
Do I need to use Fire Batt with other firestopping products?
In many cases, yes. For example, service penetrations may also require wraps, collars, or sealants to ensure the full system is compliant with test evidence.
Does Fire Batt provide acoustic benefits as well?
Does Fire Batt provide acoustic benefits as well?
Yes – in addition to fire resistance, Fire Batt also offers sound insulation, helping to maintain acoustic performance across walls and floors.
How is Fire Batt fixed in place?
How is Fire Batt fixed in place?
It’s typically friction-fitted into the opening and sealed around the edges with the manufacturer’s approved fire-resistant mastic; in our case, that would be our QSS Acrylic Sealant.
