How long you with: roof ventilation system

The basic mechanics of the air movements in the room are quite simple. During warm weather, the air inside your rooms are heats up. Since warm air rises, it tends to float out of the high ventilation spaces. This convection movement naturally draws in cooler outside air to replace the hot air that just exited.
Air that blows across the roof in that any season of the year also acts to vacuum air from the roof space. The wind blowing across the roof can create a partial vacuum on the leeward side of a roof.
But in my opinion, there is a better ventilation system available that pulls vast quantities of air from an attic space no matter from which direction the air blows. I am talking about the traditional wind turbine vents. Some people call these type of ventilation as a whirlybird vents. They are round metal ventilators that have fins in them and stick up from the roof surface perhaps 19 - 21 inches. The fins are located in a dome-shaped housing that spins each time the wind blows across it. As faster the wind speed, the faster the turbine will rotates.
As we have seen that the turbine vents have been used from many years in the residential, commercial, agricultural and industrial buildings. The vents are very affordable, easy to install, and they pump vast amounts of air from attic spaces, and give you cool and healthy environment that is good for your health and buildings.

Use of a proper roof ventilation system

So what constitutes a good roofing system? A good roof ventilation system ensures that there is balance between the air coming in and the air going out. The cross ventilation of air around the roof keeps the roof temperature bearable and also keeps the material used in the construction of the roof from reaching very high temperatures.
What constitutes a proper roof ventilation system? Actually the ventilation system for all structure is based on the principle of a wind funnel. A proper roofing ventilation system will consist of an air intake hose and a corresponding exhaust hose to ensure there is proper ventilation of air within and under the roof. The passage of external air around the roof will act like a cooler and ensure the internal temperature will not rise to a temperature greater than that of the air outside. The warm air rises and creates a slight suction near the mouth of the intake hose. The relatively cooler air outside the hose removes excess heat from the underside of the sheeting as it exits the exhaust. This cycle of heat exchange regulates the temperatures of the new shingle, saving your investment in roofing from becoming a cinder.
The choice of a ventilation system will depend upon the size, shape and the material used in constructing the roof. Proper ventilation systems consist of vents and hoses in the roof such that there is balanced air flow under and over the roof. It is estimated that in a balanced air ventilation system for a roof, there is a requirement of one square foot of venting for every 250 to 300 cubic foot of air in the attic or the space immediately below the roof. This also translates to an appropriate number of vents within the roof. These vents range from static open units and turbine style ones to thermostatically operated and electronic ones. The choice depends upon how deep your pockets are and the size of the roof.
It is always advised to have an expert look at the roofing structure and then suggest the ventilation system. Ideally the roof ventilation system is designed at the time the roof is constructed. However, with time, certain blockages and other external factors tend to dislodge the air ventilation system. This requires for a re-check and re-calibration of the roof ventilation system. Care must be taken that the vents and hoses are not blocked and proper air circulation is possible and allowed within the roofing structure. It will ensure the longevity of the building and also ensure that there are no leaks and related problems in your roof for a long time.

Why we need ecoventilators for home and office

The air within homes can become stale from moisture, odors, and pollutants that penetrate the home or are generated internally by human activity and out gassing from building materials and furnishings. A constant supply of fresh outdoor air can provide a greater assurance of good indoor air quality and improved comfort. In most homes, ventilation is provided accidentally when air leaks through the building envelope. Accidental ventilation is unreliable because it is dependent on a pressure difference between indoor and outdoor spaces caused by temperature and wind variations. Too much fresh air often enters a house during cold weather causing uncomfortable drafts and high heating bills. Not enough fresh air may enter during mild weather which can lead to poor indoor air quality. Air leakage through the building envelope accounts for between 25 percent and 40 percent of the energy used for heating and cooling in a typical residence. Many new homes are being sealed to reduce this energy use. Where tighter construction reduces air leakage and accidental ventilation, active ventilation systems may be needed to provide fresh air.
A properly designed and installed ventilation system is the key to positive moisture control and will help ensure a healthy indoor environment for the occupant.
The Ecovent or Ecoventilators works by utilising the velocity energy of the wind to induce air flow by centrifugal action. The centrifugal force caused by the spinning vanes creates a region of low pressure area which draws and throws out hot air from below and fresh cool air from out side comes in. The slightest breeze will cause the turbine to spin and even after the breeze has stopped, the fly wheel affect of the rotor cage will use its stored energy to continuously remove air giving rise to ventilation. Suction is maintained even at low wind velocities. for the more details about the ecoventilators visit our webiste http://www.anchitispat.com/
