Q1: Are there any issues with the glass inside, such as steam or fogging?
A: Generally, we use 5mm +12A + 5mm double glass. Rest assured, our double glass is manufactured with precision, ensuring no steam or fogging occurs between the double glass
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all our doors and windows include frames. Mounting them on walls is perfectly feasible.
Q3: The glass broke for no apparent reason. I'm worried the rest might break too.'m afraid the rest will be broken
The glass will only break if subjected to a significant impact force; otherwise, it won't break on its own.'t break itself.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is better to use 5mm double glass because
a sliding door with single glass looks unattractive. Using single glass creates a wide gap 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 isn't strong enough and is more likely to fall off.
