What Are Fire Batts? Uses, Applications & Selection
Fire batts are specialist boards used within tested fire stopping systems to protect suitable openings and service penetrations through fire-resisting walls and floors. They are commonly combined with sealants or other components as part of a complete system.
Use this guide as a practical introduction, then check the relevant tested system and manufacturer documentation before selecting or installing a product.

Fire Batt Guide
Quick Guide
Fire batts are specialist boards used within tested fire stopping systems to protect suitable openings and service penetrations through fire-resisting walls and floors. They are commonly combined with sealants or other components as part of a complete system.
Key Points
What You Need to Know
Walls
Used in suitable penetration seals through fire-resisting walls.
Floors
Some systems are assessed for floor penetrations.
Cable Services
Often used around cables and cable trays.
Mixed Penetrations
Certain tested systems cover combinations of services.
Key Principle
What Are Fire Batts?
Fire batts are typically rigid or semi-rigid mineral fibre boards with a specialist coating. Their purpose and tested applications vary by manufacturer and system.
They are not simply insulation boards. Fire stopping batts should be selected according to the evidence covering the construction, services and opening involved.
Practical Guidance
Where Are Fire Batts Used?
Fire batts are commonly used in walls and floors where cables, pipes, trays or other services pass through fire-resisting construction.
They may also form part of larger penetration sealing systems where multiple services pass through a shared opening.
Selection & Application
Fire Batts and Sealants
Many systems require the batt to be installed together with a compatible fire-resistant sealant or coating. The sealant may protect perimeter joints, service interfaces or other defined parts of the system.
Mixing products from unrelated systems should not be assumed acceptable unless supported by appropriate evidence.
Important Detail
Choosing a Fire Batt System
Important factors include the wall or floor construction, opening size, service type, service spacing and required fire performance.
Installation depth, coating details and the treatment of services should follow the manufacturer and tested system requirements.

Frequently Asked Questions
Frequently Asked Questions
A fire batt is a specialist board used within tested fire stopping systems to protect suitable openings and service penetrations through fire-resisting construction.
No. A fire stopping batt is a specialist system component with defined evidence and installation requirements.
Many tested systems use batts together with compatible sealants or coatings. The exact arrangement depends on the system evidence.
They can be used in tested systems covering suitable pipes, cables and other services, but the application must fall within the product system evidence.
Components should not be substituted or mixed unless the relevant evidence confirms that the combination is permitted.
