Joint Sealing

For the function and the durability of the building envelope joint sealing is of key importance despite the fact that it is only a small part of the whole construction. The purpose of joint sealing generally is to prevent passage of media (air, water, chemicals, smoke etc.), to provide thermal and sound insulation, and to enhance the visual appearance of the whole construction. The tightness of buildings and hence the role of sealants becomes more and more important in order to achieve low energy ratings for buildings. Without proper joint sealing it would be impossible to insulate a building sufficiently. Sikaflex and Sikasil elastic joint sealants are high-performance products that provide the necessary tightness under any environmental and load conditions. Sika’s elastic joint sealants are able to accommodate thermal and structural movements without breaking or loosing the adhesion to the adjacent building elements.
