All our double glazed windows and doors systems undergo both internal quality checks and independent tests by NATA accredited laboratories. Ensuring long-lasting, trouble-free operation with multiple energy-efficient and acoustic benefits is crucial, achieved through stringent quality control in our Sydney manufacturing facility.

uPVC double glazed windows and doors offer more than just aesthetic improvements; they represent technological advancement, superior performance, safety, and security. By having our vinyl double glazed products tested against Australian Standards and building regulations, we guarantee that your windows not only meet but often exceed the minimum standards required by Australian manufacturers.

Our vinyl window and door products undergo several critical tests:

• Water Penetration Test: Ensuring no water leakage into the building.

• Air Infiltration Test: Measuring air leakage to guarantee energy and acoustic performance.

• Ultimate Strength Tests: Testing with negative and positive wind pressures to ensure durability under extreme conditions.

• Deflection Test: Assessing deflection limits under wind pressure.

• Operating Force Test: Confirming that moving parts operate normally without strain.

These tests simulate real-life scenarios including operating force, air infiltration pressure, high wind, rain, and noise, ensuring that the windows can handle both daily use and harsh environmental exposure.
