How Long Does Black Plastic Sheeting Last?
The average lifespan of black plastic sheeting in full sun can vary depending on various factors, including the quality of the plastic, its thickness, the intensity of sunlight, and local environmental conditions. However, as a general guideline:
-
Low-Quality Thin Plastic: Low-quality, constuction grade thin black plastic sheeting, such as standard polyethylene plastic, may last anywhere from 6 months to 2 years when exposed to direct sunlight. These materials are more susceptible to UV radiation damage and can become brittle and deteriorate relatively quickly.
-
High-Quality Plastic with UV Inhibitors:
Sure. Here is a comparison of virgin grade polyethylene black plastic sheeting and construction grade plastic sheeting in full sun:
Feature Virgin Grade Polyethylene Construction Grade Polyethylene Material Made from virgin polyethylene, which is a high-quality plastic that is more resistant to UV degradation Made from recycled polyethylene, which is less expensive but not as resistant to UV degradation Thickness Typically 6 mil or thicker Typically 4 mil or thinner Weight Typically 1.5 oz/yd² or heavier Typically 1 oz/yd² or lighter UV resistance More resistant to UV degradation Less resistant to UV degradation Durability More durable and longer-lasting Less durable and shorter-lasting Price More expensive Less expensive In terms of full sun, virgin grade polyethylene black plastic sheeting is the better choice. It is more resistant to UV degradation and will last longer than construction grade plastic sheeting.
Black plastic sheeting that is specifically designed with UV inhibitors can last significantly longer, often up to 5 to 20 years or more when exposed to full sun. The UV inhibitors help protect the material from the harmful effects of ultraviolet radiation, making it more resistant to degradation, cracking, and brittleness.
It's essential to note that these estimates are general guidelines, and actual lifespan can vary based on the specific product, local climate conditions, and how well the plastic is maintained. Additionally, factors like the angle and intensity of sunlight, temperature fluctuations, and exposure to other environmental stressors can also influence the longevity of black plastic sheeting in full sun.
