Skylight / July 11, 2018 / Nicolas Charlebois
After the hole is cut the skylight frame is simply attached to the roof sheathing with L-brackets and then the installation is completed using the factory-supplied flashing kit. Ease of installation superior insulating qualities less tendency to scratch and a cleaner finished appearance all add to the popularity and somewhat higher cost of glass skylights. Glass skylights also have a greater number of optional accessories. These include tempered laminated or wire glass; shades and blinds for light control; glass tints for heat retention or to block sunlight; and the ability to open fully or partially for ventilation. Domed acrylic skylights are less expensive than glass.
Obviously skylights provide added day lighting and they may even offer ventilation. However heat gain and loss is also a consideration you should make. Many modern skylights feature sun tracking lenses or mirrored surfaces that provide light without heat loss or gain. Moreover whether a fixed skylight or similar alternative is better than a ventilated skylight is a question youll want to answer. Remember ventilating can help with temperature control but it is also important for preventing the buildup of moisture. Take some time to speak to your skylight or roofing professional so that you can be sure to choose the right skylight.
It will also make all the difference for a skylight that doesnt have newer methods for moving condensation away from the window. It is possible that some skylights are suffering manufacturer related defects. Most worthy manufacturers of skylights or replacements will guarantee their product. A new and complete skylight will be sent and installed hopefully at no cost. It will require the same installation techniques as applied with the first but will obviously be better all around. It is often only when installing a replacement skylight that the damage caused by the original is noticed. The moisture damage caused to a roof is often hidden by the shingles and failed flashing around a skylight.
