Q1: Are there any issues with the glass, such as steam or fogging?
A: Typically, we use 5mm+12A+5mm double glass. Rest assured, our double glass is crafted professionally to prevent steam or fogging between thepanes ofglass.
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 perfectly fine.
Q3: The glass broke for no apparent reason. I'm afraid the rest will shatter too.'m concerned the remaining glass will also break.
The glass breaks only when subjected to impact force. It won't't shatter by itself.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It's better to use 5mm double glass because:
Sliding doors look unattractive with single glass. The wide space for glass with single glass requires excessive silicon.
5mm double glass is safer than 6mm single glass.
5mm double glass offers better soundproofing than 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, as double rubber isn't strong enough and is more prone to falling off than glass silicon.
