plastic vs. glass skylights

Plastic skylights are common and cheap, but are often a source of unwanted condensation and heat, and they may easily deteriorate in light and strength over time.

Acrylic and polycarbonate plastic skylights

The quality of a plastic skylight may vary, and the final efficiency and lifespan of it depends a lot on the type of plastic. Choosing a reasonable plastic skylight demands research and knowledge.

The glazing of plastic skylights is usually made with polycarbonate or acrylic materials. Acrylic skylights are more resistant to ultraviolet rays, but polycarbonate skylights are sturdier and have a longer lifespan.

Plastic skylights advantages

Plastic skylights can be a reasonable option for very specific uses involving garages, attics and non-daily used rooms. They are cheaper and lighter in weight, and resistant to shattering, which make them a good option in terms of safety hazards and short term uses.

Colors

Plastic skylights come in very different colors. White and transparent plastic are the commonest options, but there are many others. White skylights soften the light and are better to prevent glare.

Bubble plastic skylights

Most plastic skylights are curved (bubble skylights). See, for details on this issue: Bubble and Dome Skylights.
