KF 320

Our Internorm KF 320 uPVC windows are available from Thames Valley Windows throughout Berkshire, Surrey, Hampshire, and the Southeast.

The Internorm uPVC KF 320 window system features a slim, square-edged frame that combines minimalist design and advanced technology in a high-performance uPVC triple-glazed window system. This ensures excellent thermal insulation and a significant reduction in outside noise.

The frame is nearly invisible from the outside as it is completely concealed, creating a seamless, frameless, minimalist aesthetic that gives the illusion of fixed glazing but is designed as an openable window.

It’s slim, square-edged frame enhances frameless glass architecture and maximises natural light in your home. It is available in a classic white UPVC version, which offers a timeless look, or the uPVC/aluminium window, which provides a modern twist with its sleek design.

Through the glued edges of the glass pane, I-tec glazing offers excellent security and thermal insulation. I-tec Secure, a standard feature in the new KF 520, achieves a security classification of up to RC3.
