Q1: Are there any problems with the glass inside? Such as steam or fogging issues?
A: Typically, we use 5mm +12A + 5mm double glass. Rest assured, our double glass is made professionally, ensuring no steam or fogging between the double glass.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all the doors and windows come with frames. Installing them on the wall is perfectly fine.
Q3: The glass broke for no apparent reason. Should I be worried about the rest?'m afraid the rest will be broken.
The glass would only break due to impact force. It won't break on its own.'
Q4: Can I use 6mm single glass instead of 5mm double glass?
A; It is recommended to use 5mm double glass because:
Sliding doors look unattractive with single glass. Using single glass creates a wide space that requires excessive silicon filling.
5mm double glass is safer than 6mm single glass.
5mm double glass provides better soundproofing than single glass.
Q5: Can you use rubber instead of glass silicon?
A: Yes, but it can only be used on one side. The other side must use glass silicon because double rubber is not strong enough and is more likely to fall off.
