Skylight / July 14, 2018 / Onfroi Berger
When these are pulled away and removed the drenched and water damaged roof beams come into view. Moisture comes from both inside and outside. Weather isnt the only thing that causes skylights to leak. Warm air from inside the house can catch in the skylight as it rises on warm air and then drips down onto furniture and valuables below. Modern skylight replacements can come with what is called low-e glass. This low emissivity glass keeps energy meant to heat or cool a room in and helps to reflect heat and cold out and away from the light itself. This is usually done through a special film that the glass is coated with. This film can block out UV rays and comes in many different filtering shades.
For one thing skylights are positioned in such a way that they are inaccessible unless they are operated by remote. Even in cases of motorized skylights which are easily manipulated there are still some disadvantages that are inherent to skylights that are not present or minimized in windows. Vertical windows lose less heat by convection when compared to skylights. Also since windows are generally protected by overhangs or shrubs they lose less heat by radiation. On the other hand skylights are directly exposed to the sky. Thus they lose more heat by radiation. Proper insulation can reduce this heat loss to a large extent. In the summer season skylights are more exposed to the direct heat of the sun than windows.
Tubular skylights An alternative to the conventional skylight which looks like a window in your roof is the tubular skylight. The tubular skylight is a roof-mounted dome which collects natural light and delivers it to the room below. It is less expensive than the conventional skylight because it is designed to fit between roof and ceiling framing eliminating the need for structural modifications. You will commonly see these used in bathrooms hallways and closets but they can be used in any room of your house. The average tubular skylight ranges in size from 10 - 21 inches in diameter which lights a 100-600 square foot interior space.
