Save energy
How does it work?
Sixty years ago, building heating was changed over — from radiant heat to warm air. Ever since, the consequences have been under repair.
The U-value describes a condition that does not exist in a house
Due to the change from radiant heat (stove heating) to convective heat (central hot water heating) in building heating systems about 60 years ago, structural defects arose. They were subsequently supposed to be remedied by problem solutions — insulation, insulated glass windows, additional ventilation systems — but instead they led to more and more problems, especially when it comes to human health. The Energy Saving Ordinance is supposed to lead to less energy being consumed, but unfortunately the opposite is the reality.
In building physics, stationary conditions are assumed for the theoretical calculation of the heat requirements of buildings. The U-value, which describes the theoretical instantaneous or steady-state condition, is completely impractical and can only be simulated in a climate chamber in the laboratory. Wind, humidity and solar radiation in and on building shell construction are significantly involved in heating energy consumption.
Dry building components can be heated
The prerequisite for heating cost-saving alternatives is to create dry and therefore heatable building components. Contrary to conventional heating systems, in which warm air is generated in living spaces, the temperatures of the surfaces inside the outer walls have to be raised.
Wherever there are people, animals and plants, wherever climatic conditions determine our lives, it is transient and dynamic conditions that lead to heat loss in buildings.
Regulate humidity. Temper surfaces. Reflect heat.
The simplest objective — and the thread running through every product.
