Q1: Are there any issues with the glass inside? Does it have steam or become foggy?
A: Typically, we use high-quality 5mm+12A+5mm double glass. Rest assured, our expertly crafted double glass ensures no steam or fog forms between the layers.
Q2: Do all these doors and windows come with frames for wall mounting?
A: Yes, all our doors and windows come with frames, making wall mounting a breeze.
Q3: If the glass breaks without any reason, should I worry about the rest breaking?There is no need to worry; our glass only breaks under significant impact forces—it will not 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:
Sliding doors appear less attractive with single glass. The wider glass space would require excessive silicone if single glass is used.
5mm double glass is safer than 6mm single glass.
5mm double glass offers superior 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 use glass silicone because double rubber lacks strength and is more prone to detachment.
