Is Clear Acrylic Weather Resistant ?

One of the most frequently asked questions about acrylic sheeting is how weather resistant it is. Acrylic is used in a variety of outdoor projects. For example, it is used to replace windows in sheds and greenhouses. Therefore, it’s worth knowing just how weather resistant the material can be, and how long it will last when exposed to high UV and moisture levels, or environments where the temperature can fluctuate.

Acrylic displays a level of weather resistance that other general-purpose plastics can’t match. It is able to withstand long-term exposure to high UV levels, extreme cold, dramatic changes in temperature, and saltwater spray without fogging, shattering, or otherwise losing its luster.

Clear acrylic has actually been known to last for decades – up to 30 years – when used outdoors without losing strength, crumbling, or yellowing. That makes it the ideal material for greenhouses. It provides the clarity and aesthetic appeal of glass with a greater degree of resistance to impacts, mildew, mold, and moss that can obscure glass.

Please note that clear acrylic and colored acrylic offer differing levels of weather resistance. While colored acrylic is similar in terms of strength and resistance to dirt and mold, it can fade when exposed to direct sunlight for extended periods of time.
