What Thickness Of Plastic Sheeting Should You Use For Your Project?

What Thickness of Plastic Sheeting Should You Use For Your Project?

What is thicker? 4 mil or 6 mil plastic sheeting? When measuring plastic sheeting the higher the numerical value the thicker the plastic/poly.  Therefore, 6 mil is thicker than 5 mil, 4 mil and so on. Does thickener mean it’s stronger? If neither thickness of plastic has any additive or string reinforcement, thicker is stronger depending on the application.

Which plastic sheeting is STRONGER? 

A 6 mil virgin polyethylene sheet of plastic, or a 6 mil string reinforced virgin polyethylene sheet of plastic? Both films are relatively the same thickness, but the plastic with the nylon string running through it is stronger. String reinforced plastic sheeting is tear resistant and thus can stand up to wind and the elements better.

What is engineered plastic that is string reinforced?

Depending on the manufacturer, high quality polyethylene plastic is laminated together with  a layer of string reinforcement.

Not Sure What Thickness You Need For Your Project?

  1. What is the plastic sheeting protecting?
  2. For what period of time and under what conditions must the plastic hold up? Sun, wind, heat, chemicals, etc.

Common Uses For Different Thickness of Plastic Sheeting

Heavy Duty Plastic Sheeting:

Heavy Duty Plastic Sheeting- what is it? It first boils down to what job will the plastic sheeting be required to perform? A six mil reinforced film can be considered "heavy duty" when it is used to cover a desk to keep it clear of dust. That same "heavy duty sheet" would not be strong enough to line a landfill.  Understanding the strength and thickness of the film, its composition and additives and chemical make-up as well as the job it has to perform will help determine if a film is fit for the job at hand. It is critical that the film not only be assessed on its mil thickness.  For example, if the film is in the sun, it needs UV protection additives to maintain its strength.

How Long Does Black  Plastic Sheeting Last?

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:

  1. 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.

  2. 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.

Is All Plastic Sheeting Waterproof.....NO!

Posted by Lee Hinsley on Thu, Mar 17, 2022 @ 08:33

Not all plastic sheeting is waterproof.

Of virgin resin, engineered plastic sheeting is waterproof! HOWEVER Construction and Agricultural grade sheeting (C&A), is not normally considered waterproof.
C&A film (often referred to as visqueen) can have pinholes, fisheyes, and other imperfections, which are considered normal for those grades of sheeting. These imperfections generally keep this grade of plastic sheeting from qualifying as waterproof. 
Liner grade sheeting is not supposed to have any pinholes or other significant imperfections, which would allow water to leak from the liner. So liner grade (and all our engineered films) qualify as being waterproof. 
Water vapor transmission happens at a microscopic level, where water is a vapor (gas) rather than a liquid. Microscopic levels of vapor transmission do not keep a liner from being waterproof.

What is a good vapor retarder?

The goal of a vapor retarder is to reduce the rate at which water vapor can pass through a the plastic sheeting/liner/ vapor retarder.Putting down any sort of plastic sheeting while waterproof does not stop water vapor from passing through. Understand the perm rating of the liner before you begin your project.
