As of January 2011, Groenenboom has insulated and renovated its entire spraywork unit. All of the walls and the roof have been equipped with fire-retardant insulation. The accompanying drying tunnel in the line process has been completely insulated. This in order to guarantee a better quality of the spraywork. We have improved the process of drying and hardening the paint. Quality comes first at Groenenboom. The 2 components of the high solid coating are applied while warm in a heated environment. The renovation was a huge task.
