Hi there, We are deciding between Culmax, (now Maxlight) and Cortizo. We went to visit Maxlight factory and they look really good. We also visited a site that my builder is putting the Cortizo ones and they equally look great. We will probably go with Cortizo only because they do various options for other doors that we also need. And price will be slightly cheaper. My contractor is the Cortizo importer. So if you look at their website and like them he can give you a quote. Good luck with your choice. We also looked at IQ but way too expensive and the other 2 are as good.
