70 mm systems C70 Gold® externally beaded sash

This externally beaded sash, is 70mm in height and has an ovolo bead detail to the external face of the sash. 

The design also gives the appearance of a deep putty line, to create a more authentic looking single glazed timber window, yet in double glazed PVCu. This sash can also be combined with Kömmerling’s O70 Gold® outer frame and transom to create a fully ovolo finish to the inside. Because of the deeper putty line glazing design, the face of the window has been reduced by 40%. This narrow face width and asymmetrical feature is critical to making an equal sightline design which replicates a single glazed timber window.

Like all of our window and door systems, C70 Gold® is packed with innovative product features. The 5-chambered design is far more energy efficient than the 3 chambered designs of yesteryear, resulting in more cost effective glass options for fabricators, installers and specifiers. With Building Regulations planned to change again in the near future, our PVCu window and door systems will lead the way.

With over 40 rich colours and realistic woodgrains, there are a huge number of finishes in which to enhance the externally beaded C70 Gold® system, making it a feature on any home, apartment or commercial property.
