Skylight / July 12, 2018 / Odo Vaillancour
A skylight is like a window which has been placed in your roof. It has a frame specially designed to withstand rain and prevent leakage from rain and snow. To maximize a skylights use of natural light to illuminate a room or its passive solar heating potential you will want to take into consideration how a skylight is positioned. Facing north your skylight will provide fairly constant illumination but will not provide a lot of heat. Facing east it will provide the maximum amount of light and solar heat gain in the morning. Facing west your skylight provides afternoon sunlight as well as heat gain. A skylight facing south provides the greatest potential for winter passive solar heat gain than any other location but will often allow unwanted heat gain in the summer.
Since most skylights are meant to be installed on a roof with asphalt shingles you may need to pay extra for flashing if you have tile or metal roofing. When you think of skylight design you may think that only refers to the visible shape of the panel chosen; in fact there are many aspects to skylights that relate to the design and affect the usefulness of the skylight.

This will help you to understand better the decisions you will have to make. Skylights are beneficial to have in your home for many reasons.
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.
