Profile Features

Glass Sash

The KF 320 is unique among our uPVC systems in that the design tricks the naked eye. At first glance, it appears as a fixed piece of glazing, but discreet handles and a glass sash allow it to open and close as our other systems do.

Flush Profile

Flush sash windows and doors are fast becoming popular for end users, making them an excellent option for your commercial project. A narrow, square edged design is incorporated to complement the flush fitting KF 320 uPVC system.

Triple Gaskets

All Internorm windows, including the KF 320, have triple gaskets around the perimeter. In doing so, weatherproofing is achieved to a reliable, comprehensive, and long lasting standard. End users are protected against the elements with Internorm products.

Surrounding Bonding

Our I-tec Glazing is fitted with surrounding bounding upon installation. This enhances the thermal efficiency of the KF 320 uPVC system, while simultaneously making the window harder to damage or break into, improving security standards.

Handles

Straight line handles are the standard offering for the KF 320. They are easy to operate for the end user and add a stylish finish these uPVC systems. They are superb for all commercial projects, whatever the sector.
