Roof Ventilation for Double Story Dwellings

 
During the summer months a house absorbs incredible amounts of heat, more so if the roof is a dark colour.    

The roof area begins to build up pressure somewhat like a pressure cooker.
This heat load will eventually overload insulation and make comfort levels below unbearable.

In a double storey situation the total heatload of the house ends up upstairs vis the stairwell. Cooling the attic area, in and of itself, is not going to make a great deal of difference.The main problem is the collection of heat in the living areas of the upper level. A means of allowing the heat to escape up through the ceiling and out the roof ventilator needs to be employed.

Air-conditioned houses, either refrigerated or evaporative, benefit considerably by having a Condor Kinetic Roof Ventilator installed, to eliminate air conditioner overload and reduce power usage.

Ceiling registers are manually opened and closed on demand to control heat loss during winter. Electrically operated airflow controllers are also available.

This is a general indication as to what is required in respect to roof ventilator sizes using Condor technology.

There are variables to be considered, such as type of airconditioning and airconditioning ducting as well as colour and roof material

One appropriately sized roof ventilator is always more efficient that multiple smaller.
