Our elegantly designed bifold doors consist of two or more interconnected panels that fold away seamlessly in a concertina style, lying flat against one side when open. These folding patio doors are unparalleled in inviting the most natural light, offering expansive and uninterrupted views.

Q1: Are there any issues with the glass inside, such as steam or fogging?
A: Typically, we use high-quality 5mm+12A+5mm double glass. Rest assured, our double glass is professionally crafted to prevent steam or fogging between the double glass layers.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all the doors and windows include frames. Installing them on walls is straightforward.
Q3: What if the glass breaks without any apparent reason? I'm concerned the rest might break too.
The glass would only break due to an impact force; it won't break on its own.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is advisable to use 5mm double glass because:
1. Sliding doors look unattractive with single glass. The wide space would require excessive silicon to fill.
2. 5mm double glass is safer than 6mm single glass.
3. 5mm double glass offers better soundproofing compared to single glass.
Q5: Can you use rubber instead of glass silicon?
A: Yes, but only on one side. The other side must use glass silicon because double rubber isn't strong enough and is more likely to fall off.
