Why spec this one
MB-86N SI is the premium aluminum entry door in the Aluprof line. Same 77 mm thermal-break platform as the MB-86N SI window line. The right call for projects that already spec MB-86N SI windows and need a matching entry door.
Three reasons to pick MB-86N SI over the rest of the line:
- Top thermal performance with standard hinges. Ud = 0.83 W/(m²K), the best in the aluminum entry door range alongside D-ART Line. The 3-chamber thermal break with insulating inserts is recommended by Aluprof specifically for energy-efficient construction.
- Hidden hinges available for flush panel. Standard configuration uses traditional butt hinges. Flush-panel configurations can specify hidden hinges as an upgrade — a path to the D-ART Line aesthetic while staying on the MB-86N SI hardware platform.
- Matches the MB-86N SI window line. Same architectural language, RAL color program, and hardware philosophy. For projects that spec MB-86N SI windows across the building, the entry door is the matching slab.
D-ART Line is the specialist if hidden hinges are the primary spec driver. MB-86N SI is the general-purpose premium choice when the project needs broader flexibility — standard hinges, optional hidden hinges, glazing options, slab options.

Full technical detail
MB-86N SI entry door is Aluprof’s premium thermally-broken aluminum entry door system at 77 mm build depth. The system uses extruded aluminum profiles with 3-chamber thermal break geometry, polyamide thermal break strips with insulating chamber inserts, and a thermal insulation insert in the slab core. Ud = 0.83 W/(m²K) is achieved with standard double-pane glazing where the door includes a glazed section.
The thermal break specification matches the MB-86N SI window system, providing visual and performance consistency on projects that spec the entry door and windows from the same product family. Both systems are recommended by Aluprof for energy-efficient construction.
The signature flexibility is the dual hinge specification. Standard configurations use 3 two-leaf hinges, partially visible on the hinge edge when the door is open. Flush-panel configurations can specify hidden hinges as an upgrade, which mortise entirely into the frame and slab edge for the uninterrupted slab face that defines D-ART Line — delivering an equivalent aesthetic with broader hardware flexibility on the rest of the spec.
The seal configuration uses 2 EPDM perimeter gaskets. The aluminum threshold with thermal break strip is standard. Hardware includes 3-point multi-point locking, 3 two-leaf hinges as standard (with hidden hinge upgrade option), aluminum handle, mounting cylinder, and Smart Lock / electronic strike compatibility. Smart Home integration is available across selected configurations, matching the MB-86N SI window line.
Color options include over 200 RAL colors in matte and gloss powder coat, anodized finishes for coastal and high-corrosion applications, and wood-grain decorative coatings on selected colors. Slab configurations include standard panel with butt hinges, flush panel with hidden hinges, glazed panels (top/half/full-lite), sidelite and transom configurations, custom slab designs, and custom cladding (wood veneer, stone, composite).
Application range is premium modern residential primary front entries, contemporary multi-family entries, energy-efficient and passive house residential, modern statement entries with flexibility on slab style and hinge type, and replacement work on contemporary aluminum-clad homes — particularly projects that spec MB-86N SI windows for consistent architectural language. NFRC-equivalent thermal data, hidden hinge detail drawings, and slab design catalog are available by direct request.

Where it fits
Spec it for
- Premium modern residential primary front entry
- Projects matching MB-86N SI windows across the building
- Contemporary multi-family penthouse and premium tier entries
- Energy-efficient and passive house residential where the entry door thermal needs to match the envelope
- Replacement work on contemporary aluminum-clad homes
- Modern statement entries needing flexibility on slab style, hinge type, and hardware
Don't spec it for
- Hidden hinges as the primary spec driver (use D-ART Line, engineered around hidden hinges as standard)
- Budget aluminum applications (use MB-70HI or MB-70)
- Fire-rated assemblies (use MB-78EI)
- Large-format pivot entries (use PIVOT)
Within the line
MB-86N SI matches D-ART Line on Ud (0.83) but with broader configuration flexibility. D-ART Line is the specialist when hidden hinges are the only thing that matters; MB-86N SI is the general-purpose premium choice with more options.
