Maintaining the condition of the windows already in place is the first major hurdle. With that in mind, Van Ruysdael has developed a technique for insulating glass that is fundamentally thinner, lighter and more attractive. It is many times stronger and longer‑lasting than any other insulating glass available on the market. It can easily be incorporated into existing windows, ensuring they remain attractive and robust. It strikes the perfect balance between the use of insulating materials and a healthy climate. It is nearly impossible to tell the difference between this insulating single-glazing solution and regular single-glazing. As a result, the incidence of light, ambience and space retain their impact.
