Aluprof Windows and doors | Ontario
Aluprof MB-86N Windows and Doors for Ontario homes.
MB-86N is the higher-performance Aluprof aluminium window and door direction with ST, SI and SI+ insulation variants.

Profile purpose
What MB-86N is for.
ECOWIN presents MB-86N for clients who want stronger thermal planning, larger glass packages and a more premium aluminium platform. It is a strong fit for custom homes, black exterior frames and exposed openings where frame strength and warm glass must work together.
- 86 mm profile depth direction for windows and doors.
- ST, SI and SI+ variants allow performance planning by project.
- Suitable for warm triple-pane glass packages when dimensions allow.
- Strong match for modern homes with larger aluminium windows.
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-86N. Final performance depends on size, variant, glass, colour, hardware and installation.
