Q1: Are there any potential issues with the glass inside, such as steam or fogging?
A: Typically, we use 5mm+12mm+5mm double glass.Our double glass is professionally crafted, ensuring no steam or fogging occurs between the glass layers.
Q2: Do all these doors and windows come with frames to mount on walls?
A:Yes, all the doors and windows include frames. Installing them on walls is straightforward.
Q3: If the glass breaks without any apparent reason, should I be worried about the rest breaking?
A: The glass will 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 recommended to use 5mm double glass because:
A sliding door with single glass looks unattractive. The wide space for glass would require excessive silicon filling.
5mm double glass is safer than 6mm single glass.
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 as double rubber isn't strong enough and is more prone to falling off.
