Moisture, when not controlled, can have a devastating effect on an overall building enclosure. But, when it comes to the building envelope, it’s not just the floor you need to worry about. Moisture intrusion can enter in a variety of ways, whether as a solid, liquid or gas. It can leak in through porous building materials, flow in through gaps in cladding, form as condensation when there are temperature differentials or intrude in a variety of other ways.
However it happens, improper water barriers can affect the air quality and result in serious health risks for those inside the building. Mold and mildew due to liquid buildup can cause upper respiratory problems in occupants, including coughing, shortness of breath, wheezing, asthma aggravation or cause other complications. Damp or wet environments can also degrade the structure’s physical stability. Rusting metal beams, rotting wood barriers and floors and other effects can be costly and dangerous. In fact, moisture intrusion is one of the largest factors affecting the building’s durability overtime.
