Condensation can be an incredibly disruptive problem in Alberta’s commercial and industrial sector all year round. The reality is that no particular type of construction is immune. So what exactly causes condensation, and why is it so undesirable? We answer those questions and give some solutions to this age-old issue.
The Trouble With Damp
Condensation may seem harmless, but those little droplets can cause a lot of trouble. Over time, the dampness creates an excellent breeding ground for mould and decay. Not only is this unsightly, but dangerous. Mould can cause a plethora of health problems while the decay is literally breaking down the surfaces where the condensation is living. This means that walls, roofs, and equipment are all deteriorating at an unusually rapid pace.
Inside and Out
All air contains some level of moisture in the form of water vapour. Higher temperatures can hold more water vapour than lower temperatures. This means that changes in temperature can cause excess moisture in the air to turn from a vapour to a liquid. That liquid settles on the nearest surface. There are two types of condensation:
- Surface Condensation: This occurs when water vapour condenses on the surface of a cold building element.
- Interstitial Condensation: This occurs when water vapour condenses within the layers of a cold building element. This type of condensation will damage equipment and surfaces from the inside out, making it very dangerous.
Insulation Solutions
While condensation is a reality in our extreme Albertan temperatures, there are steps that can be taken to mitigate it. The most effective way to prevent condensation is to prevent moist air from coming into contact with cold surfaces. Improved ventilation and adequate heating are important factors in structural design. In addition to these tactics, insulation can further help to decrease risk of condensation. Insulation will work to control the loss of heat through walls and floors. Vapour barriers on internal facing surfaces and permeable layers on outside surfaces will also contribute to preventing accumulation of water vapour.
Unchecked condensation can cause expensive damage within any structure. As such, it is important to mollify the risk of moisture getting into equipment, walls, and flooring. Make sure that your insulation is up-to-date and can handle your specific temperature demands.
