Q1: Are there any issues with the glass inside the doors? For example, steam build-up or fogginess?
A: Typically, we use 5mm +12A + 5mm double glass. Rest assured, our double glass is professionally manufactured, ensuring no steam or fog between thepanes.
Q2: Do all these doors and windows come with frames to mount on walls?
A: Yes, all the doors and windows include frames. Installing them on walls is perfectly fine.
Q3: What if the glass breaks for no reason? I'm concerned the rest will break as well.
Glass typically breaks only 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
a sliding door looks unattractive with single glass. The wide space for glass would require us to use a lot of silicon if you opt for single glass.
5mm double glass is safer than 6mm single glass.
5mm double glass is more soundproof compared to single glass.
Q5: Can you use rubber instead of glass silicon?
A: Yes, but it can only be on one side. The other side must use glass silicon because double rubber isn't strong enough and tends to fall off more easily.
