The Cortizo Aluminium Bifold Door can be used in domestic applications as either an alternative to sliding doors, or to open up an entire wall as part of a conservatory; the system will make the most of a beautiful view or bring a garden into the home.

Used commercially in a bar, café or restaurant, the Cortizo bifold can create a glazed screen that allows in the maximum ingress of light in inclement weather, and will also easily glide to open up an entire wall in warmer weather.

Cortizo bifolds offer a choice of opening configurations to suit any application. Choose to fold the doors/panels internally or externally, place the opening at the side so the doors/panels all fold one way, at one end, to create a single entrance door for easy access, or in the middle to give the option of a double door.

All Cortizo door profiles feature a polyamide thermal break that enhances the thermal performance of the profile and improves the overall U-Value. Profiles feature EPDM high quality gaskets and weather brushes to aid weather resistance.

The Cortizo bifold complies with the requirements of Building Regulations Document L 2010. Security is assured by multi-point lock mechanisms on main opening doors/panels, and shoot-bolt locking on floating mullions.

Cortizo bifold doors have the option of either low thresholds for unimpeded, easy access, or rebated thresholds that offer improved weather resistance.

Cortizo bifolds are available in a choice of standard or non-standard colours.
