For years, GKD has also been working highly successfully on optimizing architectural mesh as a solution for effective solar protection. As a result, our meshes remain transparent when looking from the inside to the outside. When the sun is high in the sky during summer, however, the mesh reflects the sunlight, thus reducing solar input and thereby also the need for air conditioning. In practical tests, this solution enables wall temperatures to be reduced by up to 19%. When the sun is low in winter, the transparency of the mesh permits solar irradiation, thus reducing heating costs.
