Skylight Window Replacement

Skylight windows bring sunlight in through the roof of the home and often offer useful ventilation to let heat out during the warmer months of the year. Some skylight windows even serve as emergency exits in attics or low ceiling rooms. You might want to consider skylight window replacement to upgrade your old skylight window or to install a new beautiful roof window allowing more light into your bedroom or living room area.

Fixed Skylight Windows 

Fixed skylights are nonmoving. These roof-mounted windows don’t open in any way and can’t be used for ventilation purposes. They tend to last the longest and require the least amount of maintenance.

Manual Vented Skylight Windows

Manual venting skylights typically crank up and out to provide ventilation. They’re simple to operate and work similarly to an awning window. You crank the handle in one direction to open the skylight and crank it the other way to close it once again.

Electric Venting Skylight Windows

An electric venting skylight works much the same as a manual, but it’s electrically powered. This is handy for skylights positioned in hard-to-reach areas. You press a button and the skylight opens, you push another button and it closes. Some even run off solar power and have rain sensors to open and shut the windows automatically depending on the weather conditions.

Roof Skylight Windows

Roof skylight windows are the option you’ll want to choose for attic rooms with no flat walls. These windows open up and out all the way, offering the occupants a way out of the room in the event of a fire. They’re often required by code and they make an easier option than adding a dormer with a standard window.

Pros of Skylight Windows

Cons of Skylight Windows

Skylight windows are a nice option for accenting your home and bringing in more light; yet they can also ventilate a room or even provide an escape route. They often pair well with other popular window types. If you do decide to have a skylight window added to your home make sure that it’s sealed with flashing properly and consider adding in things like insulated glass and low-e treatments to help protect your home and keep it insulated.
