Q1: Are there any issues with the glass inside? Are you experiencing steam or condensation?
A: Typically, we use 5mm +12A + 5mm double glass. Rest assured, our double glass is professionally crafted to prevent steam or condensation between the layers.
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: What if the glass breaks for no apparent reason? I'm worried the rest might break too.
A: The glass would only break due to impact force. It won't shatter on its own.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is preferable to use 5mm double glass because:
1. Sliding doors with single glass look less appealing due to the need for excessive silicon filling.
2. 5mm double glass is safer compared to 6mm single glass.
3. 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 have glass silicon as double rubber is not strong enough and tends to fall off more easily.
