Skylight / July 12, 2018 / Odo Vaillancour
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.
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.
Angled where the shaft is parallel to the pitch of the skylight. It too is the same dimension as the skylight but its straight-in angle offers more light than a straight shaft. Angled shafts also are used to connect two locations that cannot otherwise be aligned. This occurs when the skylight must be installed in a particular spot - between two trusses for example - and the shaft opening is likewise limited to a particular location on the ceiling that is not directly under the skylight. Splayed or pyramid in which the ceiling opening is larger than the skylight opening in width length or both. This type although a little harder to construct is the most popular simply because it allows a smaller skylight to illuminate a larger area.
