Microscopic glass-ceramic particles in ThermoShield are stored in a special binder, similar color. This produces a vapor permeable membrane is a glass-ceramic binder and hollow particles. It directly responds to the ever-changing humidity. It absorbs moisture from the air and thus controls the overall humidity.
The membrane system is configured so that the indoor humidity is about 55%, thus the optimum values for human residence. At the same time prevents the formation of condensate, and hence the subsequent growth of mold dangerous to human health.
