❓ Frequently Asked Questions
Are there any problems with the glass inside? Having steam or going foggy?
Usually, we use 5mm+6A+5mm double glass. Our double glass is made professionally, ensuring no steam or fogging occurs between the panes.
Do these doors and windows come with frames to mount on walls?
Yes, all the doors & windows include frames and are ready for installation on your walls.
Can I use 6mm single glass instead of 5mm double glass?
We recommend 5mm double glass because it is safer, more soundproof, and provides a better aesthetic fit without requiring excessive silicone filler.
What is the difference between 90 degree and 45 degree connecting?
90 degree windows are connected by screws, while 45 degree windows are assembled by corner braces. The 45 degree corner is a newer style that is easier to overhaul.
