For the function and the durability of the building envelope jointing or 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 is generally to prevent passage of media, (air, water, chemicals, smoke etc.), to provide thermal and sound insulation which will enhance the visual appearance of the whole construction.

The tightness of buildings and hence the role of sealants is more important in order to achieve low energy ratings for buildings. Without proper joint sealing it would be impossible to insulate a building sufficiently. At Greg Brown Master Painter, our elastic joint sealants are high-performance products that provide the necessary tightness under any environmental and load conditions.
