Q1: Are there any issues with the glass, such as steam or fogging?
A: Generally, we use 5mm+12A+5mm double glass. Rest assured, our double glass is crafted professionally to ensure no steam or fogging between the double glass.
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 straightforward.
Q3: What if the glass breaks for no apparent reason? I'm afraid the rest will break too.
Glass typically only breaks 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 advisable to use 5mm double glass because:
1. Sliding doors appear unattractive with single glass. The wide space for glass will require extensive silicon filling if single glass is used.
2. 5mm double glass is safer than 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 be glass silicon, as double rubber lacks the necessary strength and can fall off more easily than glass silicon.
