MB-Slimline is an aluminium window system featuring exceptionally narrow frames, ideal for use in renovation and modernisation projects. It performs perfectly wherever subtle, minimalist window design is needed – one that preserves the authentic character of the building.
This solution combines an aesthetic inspired by the steel-framed windows of the past with today’s highest thermal and acoustic performance standards. With options for visible or completely concealed profiles, MB-Slimline fits seamlessly into historic and characterful spaces while meeting the functional demands of the 21st century.
A new life for old walls
MB-Slimline has been created for architects seeking to give new life to post-industrial halls, historic tenement buildings, modernist structures or newly designed loft-style developments. Its minimalist form, with the option of a fully concealed sash, ensures visual consistency – the difference between fixed and openable windows becomes virtually invisible.
Using technology typical of premium aluminium windows, MB-Slimline provides excellent thermal and acoustic insulation. This is particularly valuable in refurbishment projects, where open layouts, echoes and variable temperatures often occur.
MB-Slimline has already been used in many prestigious projects, including in Manchester’s industrial districts and Warsaw’s Hala Koszyki. In such spaces, the combination of historic architecture with modern window technology works exceptionally well.
Minimalism that hides advanced functionality
Behind the elegant simplicity of MB-Slimline lies an extensive range of technical features. The system allows inward-opening windows in turn, tilt and tilt-and-turn configurations. A key advantage is the Euro-groove hardware channel, providing fabricators with comfort and flexibility – it allows the use of compatible components for both aluminium and PVC windows.
MB-Slimline is also a solution for conservation specialists and architectural studios involved in restoring buildings listed as heritage sites. The windows meet modern insulation requirements while maintaining the proportions and lines inspired by traditional steel joinery. This makes it possible to design projects that balance functionality, aesthetics and respect for history.
