Polyurethane insulation offers an effective Condensation Control solution for cold surfaces.
Condensation occurs when warm air comes into contact with cold surfaces like tanks, pipes and concrete slabs and tin roofs.
When the surface temperature of a substrate is cold enough, the air in contact with the surface can no longer hold its water vapour. The water vapour condenses out of the air and settles on the surface in the form of water droplets.
This problem can be solved by the spraying of polyurethane sprayed foam insulation for condensation control.
Applying polyurethane insulation to the surface creates a seamless airtight barrier to stop moist warm air coming into contact with a cold surface. This stops condensation forming. In other words, Polyurethane insulation is most effective for condensation control.
According to Foamed Insulation Pty Ltd , polyurethane is an appropriate insulation material for condensation control because it forms a seamless airtight barrier on the substrate and it holds its shape and won’t deteriorate over time as other insulation materials do. Also, it is immune to damage from water and moisture.
