Radiant heat and moisture build up are an attic's worst enemy, working together to cause a variety of problems for your home. In many cases passive ventilation is simply inadequate in controlling these elements, resulting in high electricity bills and accelerated deterioration of building materials over time.
By increasing airflow through the attic, more heat is actively removed thus lowering the attic temperature. Minimizing attic temperatures will increase the overall efficiency of your attic insulation and reduce the amount of heat transferred into your home. The result is a more comfortable home which requires less energy to cool.
