Sonarol Exterior Door — Aluprof MB-86 System

Sonarol Exterior Door — Aluprof MB-86 Aluminum Door System

The Sonarol Exterior Door — Aluprof MB-86 System is an aluminum exterior door built on a profile platform designed for substantial glazed or panel infill. Its frame and sash profiles are each 77 mm deep, and the system accepts infill from 13.5 to 61.5 mm. That range gives the door a broad design envelope for coordinating the center panel with an entrance elevation, while the aluminum perimeter keeps the opening crisp and clearly framed. Sonarol identifies four profile constructions for the MB-86 door family: ST, SI, SI+ and AERO. These names describe available system build paths within the MB-86 family, giving the designer options for how the frame and leaf are composed. Sonarol lists a maximum sash format of 3000 mm high by 1400 mm wide and a maximum sash weight of 200 kg. Those are system reference limits for an individual sash, not dimensions for every complete entrance unit. Air Class 3, water resistance 5A at 200 Pa, and wind classes C1/B2 are also published as MB-86 system references. Manufacturer system and reference data depend on the selected MB-86 profile construction, infill and finished door configuration.

Profile options and a flexible infill range

MB-86 is useful when an aluminum entrance needs a defined profile depth and room to coordinate the infill with the surrounding facade. A 77 mm frame and sash depth gives the door section a consistent system identity, while the 13.5–61.5 mm infill range leaves space for compatible glazing or panel choices. The resulting door can be approached as both a working entrance and a visible part of the building: the infill sets the balance between a transparent center and a more private panel, and the leaf proportions determine how the doorway reads from the exterior. ST, SI, SI+ and AERO provide named profile constructions within the Sonarol MB-86 offer. Keeping the selected construction attached to the door specification helps relate its frame build and glazing choice to the finished assembly. The listed maximum sash format and weight show the scale addressed by the system family, while air, water and wind entries provide separate reference categories for design discussions. They belong to the published MB-86 system data, rather than defining the result of an unspecified completed entrance. Whether used at a home or a larger building entrance, this aluminum exterior door system offers a coherent way to coordinate profile, infill and leaf proportions in one opening. The overall composition can remain simple and modern, with the panel surface and frame finish establishing its relationship to nearby doors and windows. Sonarol groups these constructions under the same MB-86 system name, while the profile version, infill and proportions give each entrance its individual appearance.
