What our customers say about RKW ProVent®
The RKW ProVent® sack meets the premium demands that we, as a leading manufacturer of building materials and construction systems, place on our construction chemical products. Even after long transports by truck or ship, you can buy our products at the POS in a suit without getting dirty. In addition, the RKW ProVent® can be recycled, while the paper bag is actually hazardous waste. For us, it's the overall package that's right.
