What are skylights used for?

What are skylights and roof windows? Skylights and roof windows are glazed openings on a pitched or flat roof designed to provide more light to the home. As well as allowing natural light into your home, they can also allow fresh air to enter if they are openable or vented.

 

There are three main types of skylights, ventilating (sometimes called "roof windows"), fixed and tubular. They come in a range of different shapes, including flat, arched, domed and pyramid.

Tubular Skylights

Recent developments in skylight pros design use sun-tracking, open-sided cylinders; large lens-like elements; or mirrored reflectors mounted adjacent to a conventional skylight to provide daylighting without daytime heat gain or nighttime heat loss.

Such a skylight may connect to a mirrored pipe or "light pipe" with a diffusing lens that mounts on or is recessed into the ceiling of the room below. Most tubular skylights have this feature. Tubular skylight designs do not, however, provide views or ventilation.

Ventilation

Skylights can provide ventilation as well as light. Ventilating a building with an operable skylight releases the hot air that naturally accumulates near the ceiling. Ventilating skylights usually open outward at the bottom, and some units vent through a small, hinged panel. Skylights may be opened manually with a pole, chain, or crank.

Roof Windows

Larger skylights that can be used as emergency exits are sometimes called "roof windows" and are located within a few feet of the floor.

Automated Skylights

Automated units with electric motors or pneumatic devices are also available. Some models incorporate moisture sensors to automatically close the skylight when it rains.

Skylight Design Considerations

Before selecting a skylight for your home, determine what type of skylight will work best and where to place it to optimize its contribution to your home’s daylighting and

Shapes

We offer a wide range of skylights options for residential homes. People are choosing to transform their living spaces. They know the benefits of natural light and fresh air and are turning to skylight technology to create healthier homes that are as stunning as they are environmentally conscientious.

Skylights are available in a variety of shapes and sizes. The most common shapes include rectangular, circular, oval, diamond, triangular, multi-sided, and tubular.

Non-rectangular units usually use plastic glazing, but higher quality ones use glass. The glazing can be flat, arched, domed, pyramidal, or "warped plane"—flat on the low side and concave in section on the high side. Of these, the pyramidal, arched, and domed shapes offer flexibility for positioning, because their raised design allows light to enter from more extreme angles than flat or warped plane units.

The slope or curvature of the glazing also helps to shed moisture and leaves. These skylight designs also do not require the additional framing needed to slope a flat skylight for proper drainage on flat or low-slope roofs.

Tubular skylights are smaller than most other skylights. They consist of roof-mounted light or solar collectors, which increase their daylighting potential without the need to increase their size. Because the rooftop solar collector has a small surface area, tubular skylights minimize heat loss in the winter and heat gain in summer. Their small size also minimizes their impact on a home's architecture.
