Replacing cladding is only half the battle.
The other half is making sure the products you install are genuinely fire-rated, certified, and installed to the letter of the NCC — with documentation to prove it.
In the wake of Grenfell and the NSW cladding audit, the bar for product compliance has been raised significantly. Insurers, fire engineers, certifiers, and strata managers are all asking harder questions about what’s actually going on the building — and whether it can be proved.
At Atomic Projects, we install NCC-compliant, fire-rated cladding systems across Sydney residential and commercial buildings, with every product selection, installation step, and QA record traceable from purchase order to sign-off.
1. Products We Install
We specify and install cladding systems that meet NCC Group 1 or Group 2 material classifications depending on building type and fire engineer’s specification:
- MondoClad — solid aluminium panel, non-combustible, Group 1
- Alucobond A2 — FR-core ACP, Group 1 classification
- Vitracore G2 — FR-core ACP with CodeMark certification
- Equitone — fibre cement board, non-combustible, Group 1
- Weathertex — hardwood fibre and wax board, NCC-compliant
All products are specified with current CodeMark certificates or ABCB-accepted test data, and supplied with manufacturer’s compliance documentation for the QA package.
2. Installation Standards
Our installation process is governed by:
- NCC Volume 1 Section C (Fire Resistance)
- Manufacturer’s installation guidelines (mandatory for warranty and CodeMark compliance)
- Fire engineer’s specification and cavity detailing drawings
- Our Inspection and Test Plan (ITP) with hold points at each stage
3. Key Installation Steps
- Substrate and batten verification — confirm frame condition and batten spacing match panel system requirements
- Sarking and moisture barrier installation — per fire engineer’s spec
- Cavity barrier installation — ITP Hold Point 2 sign-off required before proceeding
- Panel installation — per manufacturer’s drawing set, with correct fixing spacing and edge distances
- Flashing and sealant installation — per detail drawings; all joints sealed before inspection
- Final facade inspection — ITP Hold Point 4 sign-off required before scaffold removal
4. Why Atomic Projects
Our compliant cladding installations give you peace of mind that the job has been done right — with no hidden defects, full documentation, and systems ready for certifier sign-off.
Frequently Asked Questions
How do we know the products you’re installing are genuinely NCC-compliant?
We only specify and install cladding products with current CodeMark or ABCB-accepted fire performance data that aligns with NCC Section C requirements for the building’s construction type. Every product comes with a manufacturer’s compliance certificate included in the project QA package. Where required by the fire engineer, independent third-party testing data is obtained before product selection is finalised.
What’s the difference between Group 1 and Group 2 materials under the NCC?
Group 1 materials are non-combustible — they don’t ignite or contribute to fire spread. Group 2 materials have low ignitability and limited fire spread characteristics, acceptable in certain applications under specific conditions. The required classification depends on your building’s Type of Construction, rise in storeys, and fire engineer’s specification.
Can you install over the existing substrate, or does it always need to be replaced?
It depends on substrate condition. Where existing battens or framing are structurally sound, moisture-free, and correctly spaced, we can install directly. Where there’s moisture damage, rot, corrosion, or non-compliant spacing, the substrate must be rectified first. We always carry out a substrate assessment before committing to an installation programme.
Do you handle design, or do we need a separate facade consultant?
We can work either way. For straightforward residential strata projects, our team handles system selection, detail design, and installation as a design-and-construct package. For complex or high-rise projects, we work collaboratively with your consultant team to deliver the installation scope.
What warranty do you provide on the installed cladding system?
We provide a workmanship warranty on installation, and the product manufacturer provides a separate material warranty (typically 10–25 years depending on the product). Both warranties are included in the project handover documentation, alongside contractor’s all risk insurance coverage throughout the works.
