Q5: Do you know what is a U-Factor/Value?
The U-factor/Value measures how well a fenestration product prevents heat from escaping a home or building.
The lower the U-Factor/Value is, the better a product is at keeping heat inside the building, thus is a better insulator.
The most energy-efficient window we made is Germany’s PHI-certified passive housing standard window and door, in which Uw is 0.79 W/ m2* K(metric), which turns into a U factor is 0.14 ( imperial).
Q6: What are Solar Heat Gain Coefficients?
That measures the fraction of solar energy transmitted and tells you how well the product blocks heat coming into the house caused by sunlight.
SHGC is measured on a scale of 0 to 1; values typically range from 0.25 to 0.80.
The lower the SHGC, the more a product is blocking solar heat gain. Blocking solar heat gain is particularly important during the summer season in warmer climates.
By contrast, people in cooler climates may want solar heat gain during the cold winter months to lessen the cost of heating the home.
Q7: What is the warranty on doors and windows? What do we do in case of problems?
A: 10 years quality warranty is provided, including frame unfading or peel-off, hardware, and accessories working properly under correct operation. 10 years warranty for German hardware. In case of our quality problem, we will provide a replacement by international courier.

Q12: PVC and aluminum, which is better?
A: It’s hard to simply say one is better. Each one has its advantages. PVC is good at insulation and is more economic. Aluminum is better in hardness and security.
Q13: What are the advantages of choosing aluminum casement windows?
A: The aluminum alloy casement window is sealed with multiple locking points, which can greatly enhance the sealing performance of the window. After the sealing performance is enhanced, its heat preservation and sound insulation performance will also be improved.
Q14: What are the advantages of choosing Vinyl / UPVC windows?
A: Environmentally friendly and sustainable – protects nature；
Fusion welded frames and sashes impede leaks；
Enhanced tightness, against air/ water/sound and thermal insulation, which exceed the requirements of Australian Standards.
Q15. Are you supplying standard sizes of windows/doors or customized products?
A: Both are available. We have distributors overseas, some of them are getting standard sizes of aluminum windows/doors from the YY factory, and we also supply customized products for lots of end customers, developers, and builders.
