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.
Key Highlights
- Slim sightlines maximize glass area for unobstructed views
- 2 to 7 panel configurations for openings up to 6,000 mm wide
- Inward and outward opening with traffic-door option
- Polyamide thermal break technology for strong insulation

Ideal For
Custom homes connecting living spaces to patios and gardens, kitchen-to-deck transitions, covered outdoor entertaining areas, and any project where maximizing the glass-to-frame ratio in a folding door matters.
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.
