Q1: Are there any issues with the glass, such as steam or fogging?
A: Typically, we use 5mm+12A+5mm double glass. Rest assured, our double glass is professionally made, ensuring no steam or fogging issues between thelayersof glass.
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.
Q3: What if the glass breaks without any apparent reason?I'm
concerned that the rest might break too.Theglass would only break due to impact force; it won't break on its own.
Q4: Can I use 6mm single glass instead of 5mm double glass?
A: It is better to use 5mm double glass because
single glass on a sliding door looks unattractive. With single glass, we would need to use excessive silicon to fill the wide space. Additionally,
5mm double glass is safer than 6mm single glass,
and it provides superior soundproofing.
Q5: Can you use rubber instead of glass silicon?
A: Yes, but only on one side; the other side must use glass silicon. Double rubber isn't strong enough and is more prone to falling off.
