Installing the window sill at an early stage of the project always involved risk. Dirt during construction work was the norm, and there was often damage requiring replacement. The replacement itself was also a complicated operation, often leading to facade damage. Thanks to the SMART system, this is now a thing of the past.
SMART is a patented system for installing steel and aluminum window sills that eliminates the fixed connection between the sills and the facade. The space for installing the window sill is prepared during window installation. The operation includes effective drainage and sealing, and the window sill is put in place only at the end of the project.
