2. To determine the Circumference (C) of the container, multiply the diameter by 3.14.
How to determine the length of a cover?
4. The Length (L) of the cover is determined by adding 1/2 the depth to the height.
How does plastic sheeting affect the life of the plastic?
Additives added to the plastic sheeting also affect how long the plastic will last. Plastic sheeting that has a U.V. additive added will hold up in the sunshine a lot longer than a piece of plastic that is the same mil thickness without the U.V. additive. Another common additive is the fire retardant additive. In a fire, two sheets of plastic of the same mil thickness will withstand the flame differently. The fire retardant plastic sheeting will not burn. The flame will extinguish. The non-treated plastic sheeting will go up in flame, right quick and in a hurry!!
How thick is 4 mil plastic?
Four (4) mil plastic sheeting is about as thick as a piece of paper.
What is 50 mil?
Fifty (50) mil is the thickness of a dime.
Can plastic sheets go up in flame?
In a fire, two sheets of plastic of the same mil thickness will withstand the flame differently. The fire retardant plastic sheeting will not burn. The flame will extinguish. The non-treated plastic sheeting will go up in flame, right quick and in a hurry!!
Is 4 mil paper the same as tensile strength?
4 mil standard piece of paper. Not all plastic sheeting has the same tensile strength if it is the same thickness. Take skrim reinforced (string reinforced) plastic sheeting. The layer of string or cord that is manufactured into the plastic give the plastic a great deal more strength and durability.

What is polyethylene sheet?
Polyethylene (Plastic Sheeting Liners or plastic “poly” sheet) is classified into several different categories based in part on its density and mechanical properties. The most prevalent grades of polyethylene sold is HDPE, LLDPE and LDPE: High Density Polyethylene (HDPE) has minimal branching of its’ polymer chains.
How to increase the strength of plastic sheeting?
An alternative method of increasing the strength of plastic sheeting is to add one layer of polyester string reinforcement scrim between two layers of linear low density polyethylene (LLDPE) sheets.
How thick is a mil?
This thickness is indicated as MIL (thousandth of an inch). 1 MIL is a measurement unit that equals 0.001 inch which is about the width of an average human hair.
What is the density of LDPE?
This gives LLDPE higher tensile strength and higher impact and puncture resistance than the LDPE. It has a density of 0.91-0.94 g/cm3.
Is MDPE better than HDPE?
Medium Density Polyethylene (MDPE) is less dense than HDPE and has good shock and drop resistance properties. It also is less notch sensitive than HDPE. Stress cracking resistance is better than that of HDPE. MDPE is typically used in gas pipes and fittings, sacks, shrink film, packaging film, carrier bags, and screw closures.
Is plastic sheathing versatile?
Plastic sheathing is so versatile, I have multiple MIL sheets on hand at any given time for my DIY projects.
Does Thickness Really Matter?
When it comes to vapor barriers, exceeding the code is better than just meeting it. Poly is a nice choice because it is easy, inexpensive, and comes in many different thicknesses. You want to have a thicker poly, so it is durable and less permeable. For example, a piece of paper is about one mil, a plastic grocery bag is 2.5 mils, and a credit card is 30 mils.
What is the best vapor barrier for indoors?
According to the International Energy Conservation Code (IECC), an air barrier has to regulate the indoor climate by stopping the flow of air and the moisture that comes with it. Poly is actually good at doing both, which is why using a 6 mil vapor barrier or higher is best. It can cover both requirements.
What is the thickness of a vapor barrier?
The most common vapor barrier material is polyethylene (poly). It is measured by mils, which are the thickness of the poly. Each mil is 0.001 inch and most codes call for 6 mil, which is 0.006 inches thick. However, you should not use a poly vapor barrier in your basement.
How many mils are needed for a vapor barrier?
In most states, a 6 mil vapor barrier is required. However, there are some states where you can use a 4 mil vapor barrier if you want to. In some cases, both a 6 mil and 4 mil barrier is needed.
How does an air barrier work?
This is important since air can also allow moisture in. The air barrier will minimize the heat loss through radiation, convection, and conduction. The requirements of an air barrier include: 1 It has to be strong and stiff enough to resist the forces during and after construction 2 It must be impermeable to airflow 3 It should be one continuous piece around the whole home 4 It has to be expected to last the lifetime of the home
Why is an air barrier important?
The vapor barrier can only prevent the moisture from getting in, but an air barrier helps to regulate the indoor climate by keeping out the air. This is important since air can also allow moisture in. The air barrier will minimize the heat loss through radiation, convection, and conduction. The requirements of an air barrier include:
Why use a vapor barrier?
Vapor is like a poison to your home. And it can get in many different ways because most building materials such as insulation and drywall allow the passing of vapor.
How to convert a mil to a micron?
The conversion relationship between these thickness units is: a Mil is 1000 times of an inch, the Gauge is (100) x (Mils), To go from Mils to Microns, you multiply mils x 25.4. So the calculation formulas for plastic gauge are as below.
