Skylight / July 12, 2018 / Odo Vaillancour
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.
For instance flat roofs are more susceptible to drainage problems. Flat skylights on flat roofs may lead to water pooling. That is why experts recommend the use of domed skylights on flat roofs. This promotes drainage. Skylights for low pitch installation generally have significant slope built into the design. Attention must be paid to such things before installing skylights. Skylights are introduced into the design and architecture of the home to bring in lots of light heat and warmth. But what happens if there is a tall tree towering over the skylight on the roof? The very purpose of the skylight is defeated. The position of the skylight on the roof plays a vital role in determining its usefulness and effectiveness.
Glass and acrylic or plastic skylights are available. Tubular skylights are relatively new on the scene. The small size allows them it to be used in spaces where full-sized skylights cannot. Hallways bathrooms even closets can accommodate a tubular skylight. They provide a lot of light in spite of their small size. The concept and installation process are basically the same as for a regular skylight except they have an enclosed tunnel of reflective material to reflect the light. They are available in many sizes. The small ones are 10 to 12 inch diameter and the large ones are 24 inches. Flat glass skylights come mounted in a wood or integrated rubber and metal framework and require no additional curb construction.
