Transparent thermal insulation

Transparent thermal insulation or TWD for short refers to materials that combine good thermal insulation with high light transmission.

These can be honeycomb or capillary structures, hollow chamber structures or aerogels (a translucent granulate). All materials more or less scatter the incident light; strictly speaking, these materials should therefore be described as " translucent thermal insulation". In common parlance, however, the term “ transparent thermal insulation” has established itself as it illustrates the high level of light permeability of the TWD materials.

Transparent thermal insulation is used primarily on external walls that are illuminated by the sun (called solar walls ), but it is profitable even on the north side. A darker layer in the wall, which is located behind the thermal insulation, absorbs the heat from the solar radiation and, since there is an insulating layer on the outside, releases it into the interior. Transparent thermal insulation is one of the passive forms of use of solar thermal energy .
