A house may often have problems of low ventilation which may lead to overall increase in the temperature of the house. Also the moisture in the house along with vapours from the kitchen and bath oxidize with iron articles in the house and cause them to rust. Continuous exposure to this moisture makes the various articles along with the construction of the house as a whole weak. The house not only needs to be kept free from the moisture but should have proper ventilation so as to keep the air in the house fresh and reduce health related problems for the occupants. A feasible solution in the form of a solar powered attic fan is here.

The whole idea of the attic fan is to remove or eliminate the moisture, air and vapours that accumulate at the top of the house. These substances often harm the walls and roofs. A fan that can create enough pressure to drive out these substances out should be chosen depending on the size of the room.

There are a few types of solar powered attic fans, like the flat based, curb base and gable mounted. The flat based fan is fitted on normal pitched roofs with the panel facing the sun. The curb base is for low slope roofs and the gable mounted suits an existing vent. The existing vent can be easily converted to a solar powered vent. The solar powered attic fans make the job of the air conditioner easier and it consumes less to get the temperature down.

Important Information for a Solar Attic Exhaust Fan Installation

For the installation of a solar attic exhaust fan, you have two options. First, you could hire a professional contractor to handle the job or two you could complete the installation yourself. Today, fans used for attic ventilation are much easier to install so the number of people taking this task on as a DIY project has increased dramatically. To be successful in getting the fan installed properly so it helps cool the hot attic, we have provided some helpful tips.

For starters, you need to measure the attic space that would need a vent system to ensure the appropriate fan is purchased. For this, determine the width of the attic floor, which would then be multiplied by the length of the floor. Then, that number would be multiplied by the number seven, giving you the amount of cubic feet per minute needed, or CFM (the amount of air pushed by the fan). Once you know this number, you want to choose a ventilation fan that exceeds it by 20.

You would also need to determine the size for the intake air louver. For this, multiply the CFM number for the fan by 144. That number would then be divided by 300. Typically, ridge or soffit vent systems exceed this amount in most homes but if you find that your house does not, it would be important to install an intake air vent for the opposite gable. The result would be with this on the exterior wall within the attic but below the roof, the attic fan would be more efficient.

The mounting flange would need to be measured on the inside. The easiest method would be to use a flexible tape measure so you end up with an accurate number. This piece of equipment is designed to encase the sleeve of the fan, the metal housing in which the fan resides, and it helps connect the gable framing. Keep in mind that some ventilation fans are designed without a sleeve. In this case, cross member bars are used to connect to the framing. For the direction of airflow, this would be stamped directly onto the sleeve or motor, pointing in the direction of the mounting flange.

Another part of the installation process for the solar attic exhaust fan is measuring the distance between the gable wall studs in the attic. Using these measurements, a 2×4 wood board would be cut and then nailed to the wall studs to create the opening for framing. You would also be required to measure the distance between top and bottom framing at the opening for the sides of the fan. All of these measures show the need for accuracy for installation of attic ventilation and when done right, the job would be completed quickly and accurately.

How does a Ventilating Cupola provide Attic Ventilation?

Copyright (c) 2009 Elda Titus

“More gold has been mined from the thoughts of men than has been taken from the earth.” By Napoleon Hill

The American Institute of Architects estimates 90 % of U.S. high levels of moisture in the homes.

Adding a cupola provides passive ventilation to the roof allowing trapped heat to escape with a natural flow in an upward direction through the sides of the cupola.

A roof saver, attic ventilation is all about circulating air to reduce moisture and bring in fresh air.

According to studies conducted by the U.S. Dept. of Energy and the American Society of heating and cooling engineers the benefits of roof ventilation is supported.

Insufficient ventilation can lead to moisture problems during the winter and decreased energy efficiency in the summer.

In an unventilated attic the roof sheathing may reach a temperature of 160 degrees Fahrenheit when the outside temperature is in the 90′s.

The attic heats from direct sunlight on the roof that radiates heat. This is then transmitted through the roofing material to the attic floor or the top surface of the ceilings insulation, causing the attic air to become heated.

The attic floor then acts as a “hot plate,” radiating warm air in the rooms below, causing an increase in your air conditioning requirements.

A ridge vent, such as a functional cupola, helps provide air circulation in the attic and allows for excessive attic air to escape through its sides on the top of the roof.

Suffit vents found along the bottom perimeter of the attic space, work well when used in conjunction with ridge vents to promote the circulation of attic air.

In colder climates, preventing moisture damage is a much greater benefit then in warmer climates.

Attic ventilation is required in colder climates to evacuate the warm, moist air that builds from the living space below. This air can condense causing the roof sheathing to rot.

Circulating air from ventilation helps prevent ice, dams, which form when warm air in the attic melts the snow and creates a run off that refreezes on the colder eave.

Suffit vents allow air to enter the attic at the lowest point of the roof. They are more effective when used in conjunction with a continuous ridge vent, such as a cupola.

Adding a cupola to the roof allows a way for trapped heat to escape, by providing a natural flow in an upward direction through the sides of a cupola. This passive ventilation lets the warm air escape while bringing in cool air.

Cupolas were originally designed for functionality, as a ventilating system. Today there has been a rebirth of interest in cupola for decorative architectural accent as well as the functional aspect of ventilation, and are placed on the roof tops of houses, garages, businesses.

Cupolas not only improves the attic ventilation they provide an eye-catching exterior focal point which adds warmth, tradition and a little country charm that will add value to your property for years to come.

The Types and Importance of Roofing Ventilation

Roofing ventilation is an essential part of any good roofing system.  The most important function of such vents is to provide ventilation to the attic of your home, thus reducing the heat held in your attic.  By reducing the heat in your attic less energy is necessary to cool your home, cutting down on your electricity cost.

Most building codes usually require that a home have some form of attic ventilation.  It is recommended by most building codes that a residential dwelling have 1 square foot of ventilation for every 150 to 300 square feet of living space.

There are many different styles and colors of ventilation available to consumers.  Consumers can easily find a ventilation system right for their application that is color matched to their roofing materials.

Ridge Vents & Soffit Vents

Ridge vents are long narrow vents placed on the very top or ridge of the roof.  The vents are inserted flush in the surface of the roof and as stated above are usually color matched to the roofing material used.

Soffit vents are installed in the eve or overhang of the roof and are far more common then ridge vents.  Both types of ventilation serve two very important purposes for the life of your roof.  The first purpose of the ventilation is to reduce heat and moisture, which reduces mildew and rot, thus extending the life of the roof decking.

Whether you are installing a new roof or would like to add ventilation to your existing roof it is important to consult a professional roofer.  Installation of roofing ventilation can be tricky and if done improperly can cause leaks in your roofing system.
