It is also ideal for creating containment barriers and temporary walls. One of its most common uses in construction is as a vapor barrier, preventing moisture damage in crawl spaces, walls, ceilings, and foundations. It is also used to seal joints between walls and floors to prevent air and water infiltration.

Agriculture and Horticulture

In agriculture and horticulture, 20-mil plastic sheeting is used for various applications. It is an excellent choice for lining ponds, lakes, and aquaponic troughs, providing a durable and resistant liner. It can also be used to cover livestock housing, providing protection from the elements and high winds. Additionally, it is suitable for outdoor storage covers and greenhouse covers.

Events and Recreation

The durability of 20-mil plastic sheeting makes it a good choice for events and recreational activities. It can be used for mud runs and pond skimming activities, withstanding high traffic and ensuring a reliable and safe experience.

Industrial Applications

The toughness and affordability of 20-mil reinforced polyethylene film (also known as RPE film) make it popular for industrial applications. It is often used in crawl space lining and encapsulation, providing a durable barrier against moisture and vapour. Its strength and tear resistance make it suitable for any industrial application that requires a tough poly film.

Thickness measurement

The standard unit for measuring plastic sheeting thickness is mil thickness measurement, or "mil". One mil is equal to one-thousandth of an inch (0.001 inches or 0.0254 mm). A micrometer or thickness gauge can be used to determine the thickness of a piece of plastic sheeting. Measure plastic sheeting at its thickest point. If you are measuring the thickness of a string-reinforced plastic sheeting product, take the measurement from the cross-section of the string lacing. A digital caliper is also commonly used to measure the thickness of plastic sheeting. However, measurements can vary if the plastic contains scrim reinforcement (a woven or non-woven grid for added strength). When measured over the scrim, the reading will be thicker than in areas without it, as the reinforcement adds durability and tear resistance.

The thickness of a piece of plastic sheeting will depend on its intended use. For example, thinner sheets (2 mil) are suitable for light-duty tasks such as covering furniture during painting, while thicker sheets (6 mil or more) are often used for heavy-duty tasks like vapor barriers, crawl space encapsulation, and greenhouse covers. 6 mil plastic sheeting is a common thickness for construction-grade plastic sheeting. In some cases, thicker plastic sheeting (e.g. 6 to 20+ mils) is used for vapor barriers, greenhouse films, and heavy-duty containment liners. For example, 20 mil plastic sheeting is typically used for jobs like waste or landfill liners, foundation wall vapour retarders, outdoor storage covers, and aquaponic liners. In construction, there are various standards for how thick certain plastic sheeting materials are required to be. For instance, a vapor barrier has to be a minimum of 6 mil, while the EPA requires hazardous waste HDPE liners to be a minimum of 60 mils.

The intended use of the plastic sheeting will determine the necessary thickness. For example, a greenhouse cover requires a different thickness than a pool cover. Environmental conditions should also be considered, as exposure to extreme weather conditions, harsh sunlight, wind, and rain may necessitate a thicker plastic sheet. Thicker plastic sheeting will often result in increased durability and resistance to tears, punctures, and weathering. Thicker plastic can also withstand heavier loads, harsher conditions, and provide better protection against moisture, dust, and debris.

It is critical that the plastic sheeting is not only assessed on its mil thickness. Understanding the strength and thickness of the film, its composition, and any additives, as well as the job it has to perform, will help determine if a film is fit for the purpose. For example, if the plastic will be exposed to sunlight, it will need UV protection additives to maintain its strength.

The intended use of the plastic sheeting is a critical factor in determining the required thickness. Different applications call for different thicknesses. For instance, thinner sheets (2-3 mil) are suitable for light-duty tasks such as covering furniture during painting or for moderate protection in construction and DIY projects. On the other hand, thicker sheets (6 mil and above) are used for heavy-duty tasks like vapor barriers, crawl space encapsulation, and landfill liners.

Coverage Area

The size of the area you need to cover will impact the thickness of the plastic sheeting you choose. Larger areas may require thicker sheeting to ensure durability and resistance to punctures or tears. Thicker sheets also tend to have better resistance to chemicals and other environmental factors, making them suitable for outdoor use.

Environmental Conditions

Evaluate the environmental conditions that the plastic sheeting will be exposed to. Consider factors such as temperature variations, exposure to UV radiation, and harsh weather conditions. Thicker sheets generally offer better protection against extreme weather and corrosive substances.

Anticipated Stress

Consider the anticipated stress or demands that the plastic sheeting will need to withstand. If it will be exposed to heavy machinery, prolonged usage, or harsh chemicals, opting for a thicker gauge is recommended for long-lasting performance. Thicker sheets provide superior strength and resilience, making them ideal for demanding projects.

Cost Considerations

Thicker plastic sheeting tends to be more expensive than thinner sheets. Therefore, it is important to balance performance requirements with budget constraints. Evaluate the cost implications of the thickness and determine if the additional durability and features of thicker sheets justify the extra cost.
