Fire Batts: That Fit Fast and Perform Under Pressure
BOSS Batts are high density mineral fibre fire rated batts treated with an ablative coating. They are designed to provide reliable passive fire protection in walls and floors by sealing wide linear gap seals, blank openings, large oversized apertures with service penetrations or localised substrate thickening.
Because they are lightweight, easy to cut on site and simple to install, BOSS Batts offer a practical and cost effective fire stopping solution for a wide range of building types.
Core Benefits
- Strong fire resistance with high FRL performance of up to FRL -/240/180.
- Quick and simple installation with on site cutting, friction fitment and pattress mounting
- Suitable for electrical, plumbing and HVAC services
- Helps with acoustic insulation as well as fire separation
- Versatile applications and installation methods
- Cost effective compared with complex, multi product fire stopping systems
- Compatible with a wide range of BOSS firestopping products including: FyreBox™, FireMastic-HPE™, FireMastic-300™, P40-MAK Wrap, MaxiCollars, UniWrap®, FireSilicone-EMA, Thermal Defence Wrap.
Typical Applications
BOSS Batts are commonly used in:
- Apartment buildings and residential projects
- Retail centres and commercial offices
- Data rooms and communication spaces
- Industrial facilities and plant rooms
- Mixed service penetrations in risers and corridors
They are well suited to sealing openings where multiple services pass through fire rated walls or floors, or where linear gaps seals up to 200mm are required.
How They Are Installed
- Cut the batt to the correct size so it fits tightly into the opening.
- Paint cut edges of the Batt with Ablative Coating.
- Insert / friction fit the batt into position by tapping with a rubber mallet.
- Seal any joints or perimeter gaps with FireMastic-300™.
- Treat any service penetrations with relevant other BOSS Fire products in accordance with the tested systems.
This creates a clean, compliant and repeatable fire rated system that can be installed efficiently by site teams.
FAQ
Q: What are BOSS Batts used for?
A: BOSS Batts are used to seal service penetrations, linear gaps and openings in fire rated walls and floors. They help prevent the spread of fire & smoke between building compartments.
Q: Can BOSS Batts be cut on site?
A: The batts are designed to be cut easily with standard hand tools so installers can shape them to suit different openings and gap requirements.
Q: Do they work with multiple service types?
A: Yes. BOSS Batts are suitable for electrical cables, data bundles, plumbing pipes, conduits, HVAC lines and mixed service penetrations.
Q: Are they suitable for both new builds and retrofits?
A: Yes. They are commonly used in new construction and can also be installed during upgrades or when older penetrations need to be brought back to compliance.
Q: How do BOSS Batts achieve fire resistance?
A: The high density mineral fibre core and ablative coating work together to slow heat transfer and maintain integrity during a fire. When installed correctly, the system provides strong fire separation between compartments.
Q: What fire rating can they achieve?
A: BOSS Batts can achieve high FRLs of up to -/240/180 depending on the wall or floor type and the service configuration. The exact rating depends on the substrate and overall systems that is installed.
Q: Do BOSS Batts provide acoustic benefits?
A: Yes. The dense fibre structure offers useful sound reduction, making them effective for both fire and acoustic separation.
Q: Do they require additional sealants?
A: Cut edges of BOSS Batts should be treated with ablative coating and perimeter joints and gaps must be sealed using FireMastic-300™ to complete the system.
Q: Can services be added later?
A: Yes. Installers can cut and adjust the batt if new services need to pass through the same area, provided the fire rated system is reinstated correctly.
Q: Who typically installs BOSS Batts?
A: Fire stopping contractors, electricians, plumbers, HVAC trades and general builders commonly install BOSS Batts as part of their service penetration work. In Queensland, firestopping products must be installed by licensed QBCC installers.
Why BOSS Batts Make Sense
Modern buildings contain large volumes of electrical, plumbing and HVAC services. Managing these penetrations can become time consuming and costly when using traditional fire stopping methods.
BOSS Batts help simplify the process by providing a standardised, easy to use and versatile solution that reduces labour, improves consistency and maintains compliance. They also support future service changes without major disruption to fire rated construction.
