The building components will expand and contract at different rates when different types of materials are used. The rates of movement of concrete, brick, masonry block, steel, wood, vinyl, and plastic are all different. Over time, dissimilar materials can have a significant impact on joints.Do you want to learn more? Visit Depend Exterior
Imagine a dry sponge representing the exterior of a typical building as it expands and contracts. The absolute contraction point of the dry sponge is reached. Saturating the sponge allows it to swell in all directions to its absolute expansion point. When the ambient temperature is around 70 degrees and the moisture is released from the sponge, it maintains a median state. When the outside temperature rises, the building expands, and when the outside temperature drops, the building contracts. So, think about it: how does a building’s expansion and contraction affect the components of the structure? When engineers and architects design structures, they usually take this movement process into account. To compensate for the edifice’s expansion and contraction, expansion joints are used. To seal against moisture intrusion, expansion materials are placed within the joint. Regrettably, this is a component that needs to be serviced every 5 to 7 years. The design team, on the other hand, neglects to take into account exterior coating components like the painting system. Because the exterior wall expands in every direction, the paint material must also expand at the same rate as the substrate. If different materials are used to build the exterior wall, each one will expand at a different rate, necessitating the use of a joint to keep the materials separated. As a result, whenever two materials meet on the exterior façade, a joint should be installed to separate them. Rubber, silicone, urethane, and metal are among the materials used in the joint systems used on building exteriors. The joint sealant or expansion joint material is typically installed at the same time as the exterior façade. During construction, the exterior colour is applied to the exterior façade in the form of paint. Failure will occur if paint products are applied to a silicone material during construction.
