Q1: Are there any problems with the glass inside? Will there be steam or fogging issues?
A: Typically, we use 5mm +12A+5mm double glass. Rest assured, our double glass is manufactured professionally, ensuring no steam or fogging issues 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, making wall installation seamless.
Q3: What if the glass breaks without any apparent reason? I'm concerned the rest might break too.
The glass would break only due to an impact force; 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 recommended to use 5mm double glass because
Sliding doors look unattractive with single glass. The wide space for the glass requires a lot of silicon if single glass is used.
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 be glass silicon because double rubber isn't strong enough and is more likely to fall off.
