FastWrap-XLS™
BOSS FastWrap-XLS™ is an advanced, ultra-lightweight fire-rated duct wrap engineered to deliver high-performance fire protection without slowing down installation. Designed for steel ductwork across HVAC applications, the system provides up to 120 minutes fire resistance while maintaining exceptional thermal insulation performance. Its low bio-persistent fibre core and fully encapsulated black foil outer layer ensure safe handling, durability, and a clean aesthetic finish for exposed services.
Unlike traditional wrap systems, FastWrap-XLS™ simplifies installation with a no-banding requirement, butt-joint first layer and identical internal and external fire detailing—helping contractors install faster, reduce labour costs and minimise risk on site. With proven compliance to AS1530.4 and AS4072.1, it delivers a practical, high-performance solution for modern construction where speed, compliance and buildability matter.

Key Benefits
- Up to FRL 120/120/120 performance
- Internal and external fire scenarios for horizontal and vertical ducts
- 25% lighter than comparable wrap systems for faster handling and reduced fatigue
- Ultra-fast installation with butt-joint first layer and simplified fixing methodology
- No banding required, reducing labour time and install complexity
- Black foil encapsulation for clean, exposed ceiling aesthetics
- Moisture, grease and water-resistant outer layer to maintain long-term insulation performance
- Low bio-persistent fibre technology for safer handling on site
- Consistent install method for internal and external fire, reducing errors on site
- Zero clearance to combustibles, maximising usable space
- Ducts up to 3.6m x 3.6m – offering extremely large variability
- 2, 3 & 4 sided wrap configurations – ideal for tight access
- Versatile across HVAC applications – ventilation, smoke extract, kitchen exhaust, pressurisation systems
- Wide variety of substrates – plasterboard & shaftliner walls, concrete and masonry walls, AAC and Speedpanel systems, and concrete floor slabs
Testing
FastWrap-XLS™ has been rigorously assessed by a NATA-accredited laboratory in accordance with AS 1530.4:2014 and AS 4072.1:2005, confirming compliant fire-resistance performance for HVAC ductwork. It achieves FRL -120/120/120 for internal fire exposure and FRL -120/120/60 for external or combined exposure, across both horizontal and vertical duct configurations. The system is approved for installation in a wide range of fire-rated constructions, including plasterboard and shaftliner walls, concrete and masonry walls, AAC and Speedpanel systems, and concrete floor slabs, provided the supporting structure maintains the required FRL. Ducts are approved up to 3.6m x 3.6m for 2, 3 & 4 sided applications. This ensures a versatile, code-compliant solution suitable for real-world building conditions and NCC requirements.
