Skylight / July 11, 2018 / Nicolas Charlebois
This heat gain can be minimized by installing your south-facing skylight in the shade of deciduous trees or adding a moving window covering. Skylights come in all shapes and sizes. Its size greatly affects the illumination level and temperature of the space below. As a rule of thumb the size of a skylight should never be more than 5% of the floor area in rooms with many windows; and no more than 15% of the rooms total floor area for spaces with few windows. Dept. of Energy. Glazing Like windows skylight manufacturers use different types of glazing to improve their energy efficiency. The glazing comes in three different forms. Plastic glazing - This type of glazing is usually inexpensive and less likely to break than other glazing materials.
If installed badly however they can do a great deal of damage. Many people dont realize how easily that damage can be avoided by purchasing a replacement skylight instead of giving it up altogether. A skylight might be detrimental to a house in many different ways. They require flashing when installed and without proper flashing of aluminum or some other sturdy material the light will leak. Rain and other forms of moist weather will find its way into the house itself. Roof design is very important when choosing and installing a skylight. It is another reason why skylights fail after awhile. The angle or tilt of a roof and the angle at which the skylight is set will determine how strong and supported the light is.
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.
