The extremes of Indian weather, generates the requirement of
ventilation systems. In these
air exchange ventilators air flow capacity must be balanced between intake and exhaust vents. Intake and Exhaust vents must be positioned in order to create a proper high-low balance.
Purpose of Ventilation Systems:Most of us think, that ventilation is used for removing heat that develops due to high temperature during summers. The main motive of air exchange ventilation is to provide added comfort and to provide protection from damage and deterioration caused due to heat.

As in Indian summers the high temperature encourages cripping, cracking and premature aging of roofing materials, this allows the outside heat to enter inside the house deducing the efficiency of Air conditioners working.

Where as in winters, the warmth inside the house arises moisture content leading to deterioration of wooden furnitures.
To encounter troubles caused, one requires a perfectly balanced
air handling ventilation system.
Working of Vent:Air ventilation system can't eliminate the heat transfer from roof to attic but it can reduce the effect to higher extent. And for this the requirement is a balanced
turbo air ventilation system which inherits a steady air flow. This steady flow of air carries outside the warm air, before it heats up the attic floor.
Features of Roof Ventilation System:

No operational costs

No maintenance

Turns at the slightest breeze

Reduces condensation and mildew

Unique and elegant appearance

Easy to install and fits roofs

Withstands severe wind and rain
Benefits of Roof Ventilation System:

Acts as a guard against weather and dirt infiltration.

Provides maximum visual appeal and high efficiency.

Maximum and uniform air distribution.

Helps preventing moisture from being trapped in insulation and roof deck.

Prevents deterioration of furniture, wall damage and peeling paints from walls and ceiling.

Ventilation keeps the attics cooler and drier.
