The S9000 uPVC windows system is distinguished primarily by their ability to build large structures without the need of additional bars. As standard, windows made in the S9000 system are welded using the V-Perfect technology. The STV technology of gluing the pane dry was also used – the pane is glued to the sash rebate. Additionally, the profiles are colored with acrylcolor technology.
