Kömmerling O70 & C70 Windows

C70 and O70 systems are highly regarded as one of the easiest to fabricate and install and can be complemented with a front/rear door, patio door or a conservatory.


The O70 system, with its revolutionary ovolo profile has been designed to enhance any home, offering a unique combination of classic appearance and state-of-the-art performance. The curved slimline frames and opening sashes create a ‘softer’ appearance adding a little design flair to any installation in the home.

The C70 chamfered system is a 5-chambered modern system. This system benefits from the cleaner lines of a modern chamfered suite of profiles for the design conscious.

Both C70 and O70 are extruded using lead-free PVCu Greenline compound – enabling complete exclusion of heavy metals from the entire production processes.
