Minimal Line

Space for natural light thanks to slim profiles and large glazing.

Aluminium, light and design are the keywords of modern living. Window and door frames designed to eliminate the distance between inside and outside and to ensure maximum light without sacrificing excellent thermal and acoustic insulation. METRA Building’s Minimal line meets the ambition and needs of contemporary design and is characterised by remarkably slim aluminium profiles that allow for large openings. This system therefore maximises natural light, with profile thicknesses as low as 35 mm.
Choose from windows, patio doors and balconies to find your ideal solution.

The features of the Minimal Line


METRA Building’s Minimal line is characterised by a modern design that is as versatile and elegant as the material it is made of: aluminium. Minimal space, reduced profiles and no obstacles for a modern and refined home. The slim structure of the windows and doors allows optimal entry of natural light and enables the perfect combination of indoor and outdoor spaces.


The large glazing and the slim frames allow you to enjoy the outdoor landscape and ensure essential design while still keeping heat, cold and noise outside thanks to the innovative construction technologies that best insulate the windows and doors produced by METRA Building.


The minimal line includes aluminium windows and doors characterised by minimal thickness, but with which large windows and doors can be constructed. The entire system tends to disappear, allowing an important percentage of filtering light to be recovered.
