Folding doors between the house and terrace

04 / FOLDING DOORS

Aluminium folding doors.

Open up your terrace with glazed doors that fold to the side. We make each set to fit your opening using Reynaers aluminium profiles, with the leaf layout, glazing and finish agreed with you.

  1. Aluminium folding systems

    We make glazed folding units for homes and commercial spaces. The leaves fold into a stack. We select the folding direction to suit the space available.

  2. A separate leaf for everyday access

    A separate access leaf lets you use the entrance without folding the whole unit. Its availability depends on the number of leaves and the chosen layout.

  3. Folding systems: prices and quotes

    The price depends on size, profiles, number of leaves, glazing, hardware and threshold. Send the opening width and height, plus a photo or drawing, for a quote.

DESIGN OPTIONS

Plan your terrace opening.

We select the design to suit the opening dimensions and how you will use the doors.

From 2 to 8 leaves

We select the number of leaves and folding layout for your opening. We check the space needed for the folded stacks and the remaining clear opening width.

Slimmer visible lines

ConceptFolding 77 SlimLine has a 122 mm leaf joint, compared with 144 mm in the Functional option. Maximum glazing thickness is also different: 44 mm and 63 mm respectively.

Threshold and floor level

We select the threshold together with the floor and terrace levels. We consider the step height, rain protection and drainage.

Colour and glazing divisions

We agree on a profile colour to suit the facade and interior. The number of leaves sets the glazing divisions and the space needed for the folded doors.
