Van Ruysdael creates and maintains equilibrium between heat insulation and the building’s structure.

building structure in equilibrium

The heat insulation value of glass is expressed as a heat transfer coefficient value (W/m2 x K). Until recently, it was argued that the lower the heat transfer coefficient and the better the insulation, the more energy that would be saved. However, new research has shown that this does not necessarily hold true in existing buildings – in fact, the reverse is often true. Establishing and maintaining a balance between the insulation value, the building’s structure and its use is more effective. This also creates a much healthier living environment.

glass as the coldest surface

In existing building structures, the best solution is for the glass to remain the coldest surface, as this tackles the problems of dampness, increased energy consumption, mould formation and other unhealthy consequences. Van Ruysdael insulating++ glazing achieves heat transfer coefficient values of about of 3.0–3.5 W/m2 x K, which perform better in situations like this,


The heat transfer coefficient value of thin single glazing is 6.0W/m2 x K and the heat transfer coefficient value of super insulating double glazing or Triplex glass is approx. 1.0W/m2 x K. Van Ruysdael insulating++ glass found the balance inbetween the two.
