Roof Windows - Chimney Effect:

Chimney Effect Ventilation: The most valuable asset of these windows is the ventilation that the units offer.

Also, they give us the opportunity to benefit from natural ventilation or natural air conditioning from the law of nature known as the chimney effect.

The chimney effect causes cool air to enter from lower operable windows and exit as warm air through higher clerestory windows roof windows or ventilators.

A key factor is to let as much warm air from the home escape through these upper ventilators, so the higher they can be placed within the room (closer to the peak or the high point of the ceiling slope if there is one), the more successful the ventilation will be.

These units are ideal for this design as they can be placed virtually anywhere on a roof area that is practical. Also any heat that most unwanted heat they generate through sun radiation is automatically ventilated back to the outdoors.

Another important design feature for successful chimney effect ventilation is the unobstructed pathway from the lower source ventilation to the higher source (roof window) ventilation.

Roof Windows - Tax Credits:

Energy Tax Credits: Skylights fall under the Federal Tax Credit with the following guidelines:

30% of the cost (not including installation/labor costs), up to $1,500 can be claimed.

You do not have to replace all the windows/doors/skylights in your home to qualify. And it doesn't need to be a replacement either - installing a new window where there wasn't one previously (like in an addition) would qualify.

From June 1, 2009 - December 31, 2010 windows (and doors and skylights) must have a U-factor and Solar Heat Gain Coefficient (SHGC) less than or equal to 0.30.

Roof Windows - Selecting Locations:

Since Roof Windows are a lot more versatile than fixed skylights, you open up a lot more areas in the home where you may want to introduce fresh air and ventilation options.

Any cathedral ceiling room is the perfect candidate for these units, located at the highest point available in the room. Make sure you have operable windows down low in the room to allow for the cool outdoor air to enter and cool and ventilate the room.

Rooms that develop water vapors or odors are great locations for these windows as well, such as the bathroom to minimize moisture buildup and the kitchen to help eliminate heat buildup and evacuation of cooking odors.
