From soaring summer heat to bushfire zones and energy-conscious building codes, Australian homes face some of the world’s toughest environmental conditions. Kömmerling delivers more than just high-performance uPVC windows and doors – we deliver certified peace of mind.
Bushfire-Resistant and BAL (Bushfire Attack Level) 40 Certified
Kömmerling successfully tested a range of uPVC window and door systems to BAL 40 in 2010. Since then, these products have been independently reassessed and updated to meet the latest requirements of AS3959:2018.
We have solutions that cover Bush Attack Level ratings BAL low, BAL 12.5, BAL 19, BAL 29, and BAL40.
As bushfire regulations continue to tighten, choosing systems built to endure extreme conditions is essential. Kömmerling delivers protection and performance, without compromising on design, energy efficiency, or acoustic comfort.

WERS Energy Ratings – Designed for Australian Homes
When it comes to choosing energy-efficient windows and doors, the Window Energy Rating Scheme (WERS) is the national benchmark.
WERS, managed independently by the Australian Glass & Window Association (AGWA), rates and labels window and door systems based on their annual energy impact on a whole house, across all Australian climate zones.

Kömmerling products have been independently assessed under WERS to confirm their energy performance.
AUSTRALIAN STANDARDS & COMPLIANCE
Kömmerling products are designed and tested to meet the National Construction Code (NCC) and the Building Code of Australia (BCA) requirements.
Compliance for windows and doors is achieved through AS 2047 – Windows and External Glazed Doors in Buildings, which defines performance and testing standards for Australian conditions.
Kömmerling systems are tested in accordance with AS 2047, covering the following key performance areas:
1. Structural – Measures window deflection (SLS @ Span/250)
2. Operating Force – Ensures smooth operation within set limits
3. Air Infiltration – Assesses air leakage through the window or door
4. Water Penetration – Tests resistance to water entry (WPR)
5. Ultimate Strength – Confirms compliance with ULS requirements
Our commitment to testing and compliance ensures our products perform reliably and safely in Australian homes.
