Roof Ventilators for Protecting the Roof Against Adverse Weather Conditions

Owing to the extremes of atmospheric conditions in India, a proper ventilation system is required to keep the temperature of the room stable. To maintain the temperature of the room, it is important that the high and low balance of air is maintained, therefore exhaust and intake vents are fixed accordingly. Modern air ventilator is designed in such a manner that inflow and outflow of air is balanced in the room. A general concept is that the purpose of installing a roof ventilator system is to eradicate the heat developed due to warm weather conditions in summer. But the main motive behind installing these ventilators is to protect the roof from harmful effects of heat. The sunlight has two types of radiation of which the infra-red radiations are very harmful. The infra-red radiation produces immense heat, which is enough for causing splitting, shrinkage and chalking of the roof surface. Owing to chipping of the roof, outside heat enters inside the room and reduces down the effect of air conditioners installed in there. The weathering of the roof surface and its pre mature ageing can be reduced with the use of the ultra-modern air ventilation systems. Winters have different effect on the roof such as humidity, dripping and moisture inside the room. A non-ventilated roof, because of the low temperature, causes moisture inside the room which damages the wooden furniture. A balanced air ventilation system ensures that the temperature of the roof is maintained without causing any adverse effect to the wooden furniture. The roof ventilator works in such a way that the effect of heat transfer to the attic is minimised to a greater extent, if not eradicated. With the advent of turbo air ventilation system, the problem has been solved to a greater extent as it helps in maintaining the steady airflow. It transfers the warm air outside and protecting the attic from getting warmed up. The air ventilator system is an effective guard against weathering and dirt filtration. Also, these systems have high visual appeal and greater efficiency, which helps in protection of the roof in winters and summers. The roof ventilators ensure that the air distribution is equal distribution of air inside the room. Adverse effects of climate like moisture in the roof deck are greatly reduced with the installation of these systems. The ventilation system not only protects the peeling of the paint but also helps in keeping the attic cool. Moreover, there are no operational and maintenance costs for installing these roof ventilation systems.
