Building Exterior, Expansion And Contraction Issues

The problem of expansion and contraction inside a building is plagued by land owners, building managers, engineers and architects. The building is continuously expanding and contracting with respect to ambient temperature, regardless of whether the building is a commercial, industrial or residential structure. If the building increases in temperature, the building contracts are decreased by temperature. The construction components can expand and contract at different rates by using different types of materials. There is a different movement rate for concrete, brick, masonry stone, steel, wood, vinyl and plastic. Dissimilar materials over long periods of time may have extensive effects on joints.

Imagine a dry sponge representing the exterior of the structure, to better explain how a typical building expands and contracts. At its total contraction point, the dry sponge is. Saturating the sponge; causing the sponge, in all directions, to swell to its absolute expansion point. When the moisture from the sponge is released, as the ambient temperature hovers about 70 degrees, it maintains a median state. The ambient temperature increases, the building extends, the building contracts decrease in ambient temperature. So ask yourself, how are the construction components affected by the expansion and contraction of a building?

This process of movement is usually taken into account by engineers and architects when constructing structures. Expansion joints are used to compensate for the edifice’s extension and contraction. To seal against moisture intrusion, expansion materials are inserted inside the joint. This is a part, unfortunately, that needs maintenance every 5 to 7 years. However, external coating elements, such as the painting system, are not taken into account by the design team. In both directions, the exterior wall expands, which allows the paint content to expand at the same rate as the substrate. When different materials are used to create the external wall, each material can expand at a different rate, requiring a joint to distinguish the different materials. Therefore if two materials meet on the exterior fa├žade, a joint to distinguish each material should be given.
