Good to know

Cortizo 4700 questions, answered.

What is the difference between a sliding door and a bifold?
A sliding door glides panels along a track to one side, keeping a large fixed pane of glass and slim frames, while a bifold folds its panels back to clear the whole opening. Sliders suit customers who want maximum glass and a clean view; bifolds suit those who want the opening fully open.
What does Korniche technology add to the Cortizo 4700?
It brings the fitter-friendly engineering Korniche is known for, so the door assembles and installs cleanly and runs smoothly, which keeps fitting time down.
Are aluminium sliding doors energy efficient?
Yes. The 4700 is thermally broken, with an insulating barrier through the frame to reduce heat loss, so it performs well while keeping slim sightlines.
How wide an opening can a slider cover?
Aluminium sliders can span generous openings with large panels of glass. Your sizes determine the best panel and track arrangement, and your account manager can help you spec it.
Do I need a trade account to order?
Yes. Registration is free with instant approval, trade pricing shows once you are logged in, and you can quote and order any time from The Trade Hub.
