Weather Sealing

The performance, durability and appearance of façades are critically dependent on appropriate weather sealing. The façade elements are ultimately subject to extreme movements due to temperature changes, moisture, shrinkage of construction materials, sound, wind and vibrations, which may affect the joints and adjacent elements. Natural stone elements require compatible non-staining solutions.
