What Causes Condensation?
Condensation occurs where moist air comes into contact with air, or a surface, which is at a lower temperature. Air contains water vapour in varying quantities, its capacity to do so is related to its temperature - warm air holds more moisture than cold air. When moist air comes into contact with a colder surface, the air condenses some of its moisture onto the surface.
Do I Have Condensation?
Condensation is generally noticeable where it forms on non-absorbent surfaces (i.e. windows or tiles) but it can form on any surface. It may not be noticed until mould growth or the rotting of material occurs.
Condensation Control Methods
Condensation control can be achieved by various methods. These include simple passive ventilation systems that are designed to be installed in local areas of prevalent mould and damp for local condensation control and whole flat or house positive pressure ventilation systems. These use condensation control units to ventilate the whole house from a central position, displacing and replacing moisture-laden air with fresh filtered air. PIV systems force contaminates out of the property through natural cracks and leakages. Indoor air quality is immediately improved and mould growth is eliminated.
Permagard offer a range of condensation control products to treat the effects of condensation. These include the treatment of fungi and mould to whole house condensation control ventilation systems.
