Space for the folded stack
Coordinate the folding direction and the space occupied by the leaf stack on the plan. Check that the stack leaves enough room for passage, furniture and terrace circulation.

ConceptFolding 68
An aluminium folding system for openings cleared by stacking the leaves to the side. The Functional variant is detailed here: 68 mm depth, leaf dimensions, glazing range and performance with reference calculation conditions.

What these values apply to
For the Functional variant, Uw = 1.4 W/m²K for a 3.00 × 2.30 m element with Ug = 1.0 W/m²K, a warm-edge spacer and 24 mm glazing. This describes a specific reference element, not the profile alone. The 15 mm threshold and RC2 figures do not mean every folding layout simultaneously achieves every listed class; the configuration requires a separate check.
Performance depends on dimensions, profile combinations, hardware and glazing. Each opening requires its own specification; catalogue maxima are not a guarantee for every element.
Variant availability, hardware and delivery terms in Ukraine must be confirmed for the project. A catalogue listing does not imply stock availability.
DESIGN CHECKS
From a profile to a working element.
Threshold, drainage and support
Threshold height is only one parameter. Detail the lower junction with support, drainage and its connection to the finished floor level.
68 mm is not CF 77
These figures describe CF 68 Functional. Do not transfer CF 77 or other variant figures to this element; dimensions, weight and hardware must be checked together.
