For Cortizo windows, many of these remain better suited for the European market with features such as opening inwards operation or tilt and turn.

Many of these products aren’t available in the UK where sliding doors as well as bifolding doors are most dominant.

Other Cortizo Aluminium products
The availability of other Cortizo products such as aluminium windows, residential doors or their balcony systems is very much supplier/fabricator dependent.
The vast majority of Cortizo suppliers focus on patio door products but it is also possible to find Cortizo Systems aluminium windows. Another recent innovation by Cortizo for aluminium windows is the Cortizo Arch aluminium window. This is a tilt and turn window working just like any other, but with clever hardware, that’s concealed in the frame.
The benefit of this new window product is very much aesthetics as tilt and turn window handles are by function quite a bit larger than regular casement window products.
Also quite hard to find with other systems are Cortizo horizontal sliding windows. Whilst essentially cut-down sliding patio doors, they nevertheless provide a good solution where this type of window opening is required. And with horizontal sliding sizes up to 2.2m wide and 2.6m high, the door DNA of these windows is evident.
How to buy Cortizo aluminium products.
For the British market, Cortizo provides its aluminium profiles through a network of approved fabricators and installers. Their products are also included in the sliding door ranges of well-known systems companies.
Homeowners generally have very good access to Cortizo products but with many different manufacturers, the specifications and options available vary. The finished specifications of these doors and windows very much depend on the fabricator, the options offered and whether they choose to enhance the standard product in any way.
