Aluprof Folding door systems | Ontario
Aluprof MB-86 Fold Line HD for Ontario homes.
MB-86 Fold Line HD is the Aluprof folding door direction for wide openings that need panels to stack aside.

Profile purpose
What MB-86 Fold Line HD is for.
ECOWIN presents MB-86 Fold Line HD as part of the Aluprof aluminium system family. We review it against the opening size, glass weight, insulation target, colour, hardware and installation conditions before recommending it for an Ontario project.
- Thermally insulated aluminium folding door direction.
- Useful for patio openings where a large opening width is desired.
- Panel size, threshold, drainage and hardware need careful review.
- Can coordinate with MB-86 windows and entrance doors.
Glass and installation
Warm glass, hardware and installation decide the final result.
For Ontario projects, ECOWIN pairs Aluprof profiles with insulated glass units, warm edge spacer bars, Low-E coatings, argon chambers, correct setting blocks, drainage and project-specific installation details. The same profile can perform very differently depending on the glass unit and how the opening is built.
- Double or triple glass is selected by opening size, comfort target, sound control and budget.
- Black, anthracite and large openings require careful colour, reinforcement and thermal movement planning.
- Entrance, pivot and sliding doors need hardware selected for real sash weight and daily use.
Manufacturer reference: Aluprof MB-86 Fold Line HD. Final performance depends on size, variant, glass, colour, hardware and installation.
