COR 70 Hidden Sash

Hidden sash CORTIZO system that combines high performance with a minimalist design.

COR 70 Hidden Sash TILT & TURN

A new, visually sleek and aesthetically pleasing design of Cor 70 tilt and turn windows makes them look just like a painting! The slim visible sightline has only 66mm, allowing to maximise glazed surface to let plenty of daylight inside. As an added benefit these windows come with a vast array of upgrades to conceal all unsightly hinges and even incorporate the handle into the frame (ask for Arch Invisible handle upgrade wen speaking to your sales advisor), making it almost impossible to distinguish it on the frame once in locked position!

Tilt before turn function allows for a safe way of ventilation and also ease in maintaining and keeping them clean on the outside.

Slim Frames

Narrow sightlines of only 66m, to offer visual aesthetics without compromising on thermal performance.

Thermal performance

Despite slim frames, this window can still achieve U-values from 1.0 W/m2K!

Versatile Design

Vast array of upgrades and design options with arch invisible handle!
