    FAQs About Cortizo 4600 Sliding Doors at Direct Trade Windows

    What makes the Cortizo 4600 Plus Lift & Slide different from standard sliding doors?

    Unlike standard sliding doors, the lift-and-slide mechanism raises the door slightly off the track for smooth, effortless movement and a tight seal when closed, improving insulation and security.

    How large can the panels be?

    Each sash can be up to 3,300 mm wide and 3,500 mm high, with a maximum weight of 400 kg, allowing for very large glazed areas without compromising performance.

    How energy-efficient is it?

    With Uw values from just 0.65 W/m²K (depending on glazing), the Cortizo 4600 Plus offers excellent thermal insulation, helping reduce heating and cooling costs.

    What weather performance ratings does it have?

    It’s tested to Class 4 air permeability, Class E750 water tightness, and Class C5 wind resistance for reliable all-weather performance.

    Can it be customised?

    Yes — choose from a range of powder-coated RAL colours, wood-effect finishes, anodised options, and dual-colour combinations.

    What glazing options are available?

    It can accommodate glazing up to 65 mm thick, including double or triple-glazed units for enhanced energy efficiency and sound insulation.

    Where is it most commonly used?

    Popular in contemporary homes, extensions, and commercial buildings where large, open views and high performance are required.

    Is it suitable for corners without a central post?

    Yes — the system offers a 90° corner opening option without a mullion, perfect for uninterrupted panoramic views.
