ALsisterm aluminium casement windows were created to protect any room from cold and hot weather and street noise: they’re strong, easy to maintain and resistant over time, where functionality and aesthetics perfectly match for any type of room.

In an increasingly interconnected world, cooperation is the winning action strategy. That’s why in 2008 Meral SpA joined ALsistem, a group made of ten of the most innovative companies in the sector throughout the national territory.

The main prerogative of ALsistem is the design of aluminium systems for doors and windows and continuous façades.

At Saronno’s headquarters, where all the knowledge and experience of ten technical offices can be found, products with the best thermal and acoustic insulation are created.
