Skylight / July 11, 2018 / Nicolas Charlebois
Another modern option is to have a replacement skylight with double panes of glass with a layer of argon gas infused in between the panes. New features and options make getting a replacement skylight a more viable option than just shingling over the old one. Remote controls make it possible to open and close a skylight on a whim rather than having to clamber about on ladders. Some skylights can also come with rain sensors so they will close the moment they feel raindrops or too much moisture. These options allow the skylight to vent the house while also protecting it against damage.
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.
The air near the ceiling is automatically cooled when fresh air flows in from outside. These roof skylights are so designed that they open and close a little to let in the fresh air. The glass tilts at about 45 degrees. There is a small handle to manually open the venting roof skylight. You crank the handle slightly to open or close or adjust the angle and position of the glass. The venting roof skylights are located in the ceiling of the house and are hard to reach so there is an extension to the handle. Otherwise every time you want to open or shut the venting roof skylight you will need a ladder or a high stool. Nowadays electronically operated venting skylights are also becoming very popular.
