insulation in equilibrium
While Van Ruysdael advocates the use of insulation, it is well aware that this must be done in a natural way and in a manner that is in balance with the existing environment.
In order to maintain a healthy indoor environment, the glass needs to be the coldest surface of any building's structure. Van Ruysdael glass achieves this while ensuring at the same time that more of the heat is retained indoors. In fact, insulation in equilibrium means achieving maximum performance with minimum intervention in respect of cultural preservation and heat retention, health and the environment.
In that way you can learn more about the importance of natural ventilation and condensation on glass, about the pleasant perceived temperature that is the result of the Van Ruysdael glass, and how you can achieve much greater energy conservation using glass with a relatively high U-value.
