Why Proper Fire Sealing Can’t Be Ignored

Durofire A – The Fire-Rated Sealant

To begin with, Queensland’s construction market operates under strict NCC fire compliance guidelines. However, despite these clear regulations, many tradies face costly realisations when:

1. Fire Containment Failures
   Not only do standard sealants fail catastrophically under heat (as verified by CSIRO testing), but what’s worse, they actively permit toxic smoke spread. Durofire A solves this by providing 4-hour fire resistance with zero smoke penetration.

2. Movement Accommodation
   At first glance, acrylics appear cost-effective, yet in practice, they inevitably crack with minimal movement (per ASTM C719 standards). Durofire A’s ±25% joint movement capability prevents this completely.

3. Workability Issues
   While intumescent products do provide protection, on the other hand, they’re notoriously difficult to work with (according to FPAA guidelines). Durofire A applies smoothly like standard acrylics while delivering superior fire performance.

Durofire – The Fire-Rated Sealant Solutions

Thankfully, Durofire A overcomes all these challenges simultaneously. Developed specifically to meet AS 1530.4 requirements, it delivers exceptional performance because:

✔ First and foremost, it provides 4-hour fire resistance
✔ Moreover, its ±25% joint movement capability far exceeds ASTM C920 benchmarks
✔ Unlike traditional intumescents, it offers smooth, effortless application
✔ Finally, it dries to a perfectly paintable finish

3 Critical Applications Where Durofire A – The Fire-Rated Sealant Excels

1. Penetration Sealing That Actually Performs

Whereas standard silicones fail at 300°C (UL Certified), Durofire A actively expands under heat to completely seal:

• Specifically electrical conduits (tested to AS/NZS 3013)

• Particularly plumbing penetrations

• Notably HVAC ducts (compliant with AIRAH DA08)

Expert Insight: “For optimal results, first install Backer Rod, then apply 12mm sealant depth. Most importantly, never exceed 2:1 width-to-depth ratio.”

2. Uncompromised Acoustic Performance

Although cheap sealants degrade STC ratings, Durofire A consistently maintains 60+ STC in:

• Especially apartment party walls (meeting BCA Section F5)

• Similarly hotel corridors

• Likewise office partitions

3. Cost-Effective Remedial Solutions

Traditionally, failed seals demanded complete recladding. By contrast, Durofire A bonds directly to:

• Even existing plasterboard

• Including Hebel blocks (CSR approved)

• Additionally painted concrete

Technical Specifications: Industry-Leading Performance

Durofire A – The Fire-Rated Sealant: Preparation Guide

Surface Preparation Protocol

1. Initially, clean with Cleaner to ensure proper adhesion

2. Subsequently, install backer rod for joints >12mm

3. Lastly, verify conditions via BOM data

Application Best Practices

• Always use 600ml sausage guns for consistent beads

• Crucially, tool within 15 minutes to achieve smooth finish

• Most importantly, maintain minimum 6mm depth throughout
