Q1: Are there any issues with the glass inside, such as steam or fogging?
A: Typically, we utilize 5mm +12A + 5mm double glass. Rest assured, our double glass is professionally manufactured, ensuring no steam or fogging between the doubleglasspanes.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all our doors and windows include frames, making wall installation seamless and straightforward.
Q3: What if the glass breaks without any apparent reason? I'm worried the rest might break too.'m concerned the rest will shatter
The glass only breaks due to impact forces and won't break on its own.'t shatter spontaneously.
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. There is a wide space for glass, and if you use single glass, we will need to fill it with a lot of silicone.
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 silicone?
A: Yes, but only on one side; the other side must be glass silicone. Rubber alone isn't strong enough and is more likely to fall off compared to glass silicone.
