Transparent thermal insulation (TWD) will not replace opaque thermal insulation in the future, but it will gain ground in many areas due to its promising potential for energy savings and pollutant reduction. "Transparent Thermal Insulation" - a book for planning and construction practice - provides information on materials, products, and systems, and illustrates the possibilities of this construction method developed in the last decade through realized TWD projects, taking into account energy, structural, and design aspects.
