The Internorm KF 405 Window – UPVC or UPVC/Aluminum Window
The Internorm KF 405 window can be of all UPVC in classic white or a combination of UPVC/Aluminum. It has a captivating and a consistent design and comes with a straight, square-edged, narrow window frame. This consequently reflects the minimalistic architectural design of the window. The frame is flush-mounted both inside and outside — in weather-resistant aluminum on the outside, and low-maintenance UPVC on the inside.
The Technical Details
The window looks almost frameless and modern due to the three sided rendering of the frame . It is also characterized by i-tec glazing with all around bonding of the glass pane. This ensures excellent stability, thermal insulation and security with the locking system being concealed. The thermal insulation and the sound proofing of this window depend upon what the frame is made up of and upon the type of glazing. Inside, it has 2 gaskets in sash profile (stopper gasket and centre gasket) which help with airtightness and thermal insulation. Frame connections are created through butt welding.
The window frame covers the the opening sash from the outside. Hence, this glass sash makes it look like there is no difference in the outside view between fixed and opening parts.
Protection Systems
Of course, as the other Internorm windows, the KF 405 can also be complemented with sun and insect protection systems.
The venetian blinds give the option of optimal control and deflection of light and heat via adjustable slats. Further, the attachment roller shutter and drop-down fly screen can provide additional protection from sun or insects.
