MB-RW
A modern system that meets the increasing thermal and performance requirements imposed on contemporary roof structures. It complements the range of energy-efficient aluminium systems by Aluprof.
Windows manufactured within this system are designed for installation on roofs constructed using mullion-and-transom systems from the MB-SR50N and MB-TT50 series, with a roof pitch ranging from 3° to 75° relative to the horizontal.
Roof windows can reach dimensions of up to 2.5 m between rafter/purlin axes and a maximum weight of up to 200 kg.

The high thermal insulation performance and the wide glazing thickness range of the MB-RW system (from 32 to 51 mm) make it possible to implement projects where energy efficiency is a key priority. This is achieved through the use of specially engineered insulation materials. Specially designed pressure glazing gaskets and a cover profile allow for exceptional airtightness and watertightness while ensuring simple and efficient glazing installation.
The technical capabilities in terms of hardware are another advantage of the MB-RW roof window system. To simplify the production process, the system uses dedicated hinges that can be installed at the final stage of assembly. To enable larger window sizes, the profiles can be additionally equipped with standard perimeter hardware without compromising the tightness of the construction. Manual opening using a handle is also possible.
At the same time, the system allows for the installation of electric actuators from various manufacturers in a wide range of configurations, making MB-RW windows suitable for use as part of a natural building ventilation system.
