Proterrace System is an innovative system for terraces and balconies projected by Progress Profiles to protect the edges of the tiles, the screed from water infiltrations and to allow a correct outflow of water. A complete and articulated range of multi-functional perimeter profiles, in powder varnished aluminum, in the shades white, gray, anthracite gray, dark brown, corten (on request beige) and stainless steel, which replace the ceramic “L corner pieces” and the thresholds in marble. The profiles are equipped with a punched flange, which guarantees a perfect grip with the adhesive, a vertical side that protects the screed from water infiltration and covers the edge of the flooring. The Drain version is completed with an innovative drip-guard and holes that allow the outflow of unfiltered water between profile and tiles. A system of excellence to enhance and protect exterior environments and restore full live-ability, in ideal continuity with the interiors.
