Overview

What makes the ConceptFolding 68
stand out.

Reynaers ConceptFolding 68 is a dedicated aluminum bifold door system with a 68 mm profile depth and slim sightlines that maximize the glass area. Panels fold inward or outward in configurations from 2 to 7 leaves, creating wide unobstructed openings up to 6,000 mm. Polyamide thermal break technology delivers Uf values between 2.0 and 3.5 W/m2K depending on configuration, and with triple glazing the system achieves Uw from 1.3 to 1.8. Available with 2 or 3 seals for enhanced weather performance. Any RAL color finish is available, and panel dimensions reach up to 1,000 mm wide by 2,700 mm tall per leaf.

Consider an Alternative When

If you need higher thermal performance from a bifold, the Aluprof MB-86 Fold Line HD offers deeper profiles and lower U-values. If you prefer sliding over folding, the Reynaers Hi-Finity or MasterPatio deliver wider spans per panel without stacking.
