When it comes to windows and doors, the old saying “you get what you pay for” has never been truer.

At first glance, unauthorised or unaccredited suppliers might seem like a great way to save money. But in reality, the risks can be costly, not just to your wallet, but to your home’s comfort, performance, and compliance with Australian standards.

Here’s what’s at stake:

No compliance with AS2047

In Australia, it’s illegal to sell or install windows and doors that don’t meet AS2047 compliance – the national standard for water penetration, structural strength, and air infiltration. If your windows aren't certified, they can void your insurance, lead to council issues, and ultimately require replacement.

Unproven performance in Australian conditions

Australia’s climate is no joke – from high UV exposure to cyclones and bushfires. Products that haven’t been locally tested often degrade faster, warp, leak, or fail to insulate properly. That means more heat loss in winter, heat gain in summer, and higher energy bills all year.

No accountability or support

Unauthorised suppliers aren’t part of recognised networks, which means if something goes wrong, you’re on your own. No warranties. No local backup. No peace of mind.

Why it matters

Choosing a trusted, accredited provider gives you the confidence that what you're installing is:

ICP accredited
Made with a tropical mix (for long-term UV resistance)
Locally tested in Townsville and across Australia
Backed by trained, authorised fabricators
Compliant with AS2047 and BAL ratings

At Kömmerling Australia, we only partner with certified local fabricators who meet these standards because we believe quality, safety, and performance should never be optional.

If you're unsure about your supplier, ask us. We'll point you in the right direction, even if it's not us.
