Light and transparency: the guidelines of modern design are becoming increasingly oriented towards making the environmental divisions between interior and exterior fluid. The integrated systems of the METRA Building Minimal line guarantee maximum brightness with excellent thermal and acoustic insulation. These are aluminium windows and doors characterized by reduced thicknesses. The entire system tends to disappear over large dimensions, allowing an important percentage of filtering light to be recovered, especially when mounted on small openings. The most essential products condense the thicknesses in just 63 mm. The range allows you to choose between single or double side-hung casement, tilt and turn or bottom hung and single or double leaf casement doors, as well as sliding doors, curtain walls and balconies.
