When our clients ask why we refuse to work with uncertified fabricators, this is the reason. It’s not a badge. Nor is it a marketing label. It’s a tangible, measurable contrast to the way aluminium windows and doors are designed, manufactured and installed. With GREFET, certification is a question of accountability and consistency, not cutting corners.
What Sets a Certified Fabricator Apart from the Rest of the Industry?
Aluminium window fabricators would not just handle processing and production of aluminium windows. They see them as components in a system. With GREFET, our qualified fabricators are trained to adhere to system technology guidelines on profiles, hardware, gaskets and tolerances. This ensures:
- Accurate alignment and smooth operation
- Consistent structural performance across projects
- Reduced on-site adjustments and rework
Experience alone is typically the only source of non-certified fabrications. There is value in experience, but without being homed in on a good system, results will be different.
Process Over Invention
Improvise your way through today’s problem and you’ve likely just set in motion tomorrow’s disaster. Fabricators who are certified have documented means of doing the following:
- Cutting, machining, and assembly standards
- Quality checks at every stage
- System-performance-oriented installation approaches
And that’s why windows don’t just look good on handover day. They are still playing years later with heavy use and outdoor weather.
Technical Training
Certification isn’t a one-time event. It’s ongoing. GREFET-approved installers receive ongoing technical instruction to keep up with advancing systems, new hardware and enhanced installation techniques. This training directly impacts:
- Airtightness and water resistance
- Load-bearing performance in large openings
- Sound insulation and overall comfort
When the fabrication teams understand “why” behind each detail, execution gets better automatically.
Quality Control That’s Auditable
Anyone can claim quality. Certified fabricators can prove it. We reassess our certified sites through regular auditing, reviewing the process, and measuring performance. This leads to a feed-backing mechanism for issues being detected early and fixed before installation – not after.
For architects and homeowners, that means with less issues & fewer service calls, increased confidence in the final building.
What makes a certified fabricator vs Non whilst as Others: Accountability to the Brand and the Client
And certified fabricators do not work in isolation. They represent the system brand.
For GREFET, certification enables joint responsibility. Fabricators commit to:
- Using approved profiles and accessories
- Following installation guidelines
- Maintaining service and support standards
This alignment is necessary for the system to work as advertised, not watered down.
Why Certification is So Important Now
As buildings are becoming more performance orientated, aluminium windows are not simply openings. They’re key interfaces among form, climate and daily life. Certification is the bridge between design intent and performance in reality.
At GREFET, we know that the best system is only as good as the hands that produce and install it. This is why certification is not optional for us. It’s fundamental. For in the end, what distinguishes a certified fabricator from everybody else is rather simple. Accuracy, repetition, and results you can trust.
