FAQ

     

Q: What should I look for in terms of glass properties?

A: For starters, many windows are constructed with single-strength glass. Additionally, the windows are made with double-strength glass, which means each pane is 3mm thick instead of the industry standard 2mm. Glass is stronger, more protective and won't crack or break as easily. Windows are approximately 80 percent glass, so it's important to choose a glass wrap that will help protect your home from trapping outside heat in the summer and losing heat inside in the winter. For best energy saving results, please contact us, YY's window experts can help you choose the best glass package for your home and country.

Q: Are replacement windows a good investment?

A: From day one, YY Windows starts to pay off on your investment. You can expect to use less fuel each year for heating and cooling. New windows will enhance your home's exterior appeal, which can help increase its resale value. In most cases, you can expect to recoup more than half of your replacement window costs upon sale.

Q: What is the difference between double glazing and triple glazing?

A: If they were all made from the same material and to the same quality standards, triple glazing should be around 20-30% more energy efficient. However, there are a number of variables that affect the comparison between double-glazed and triple-glazed:
The spacing between panes is correct.
The type of gas or coating used as an insulator.
Type and quality of material.
Custom made levels for your home.

Q: What do I need to consider when replacing windows?

A: Choosing the style of replacement double glazing can be a confusing choice when shopping for new windows. Many factors need to be considered, including:
a. What is the age or period of your property? Choose styles, materials and colors according to the styles, materials and colors that suit your home. Some properties may be depreciated if you have the wrong window style installed. For example, wooden windows on Georgian properties were replaced with uPVC casement windows.
b. What windows would look particularly good on your neighbor's house or similar property?
If your budget allows, it's best to replace all the windows at once for a uniform look. This also helps increase the value of your property.
c. It may be worth asking your neighbors if they are also considering window replacements, as the consistency of several neighboring properties also contributes to the added value. YY also offers bigger discounts for buying multiple properties at the same time.

Q: How do crank operated windows work?

A: Crank operated windows can be easily opened or closed by rotating the handle, and the direction of rotation determines how the window opens and closes.
