Tarps FAQ

What tarp cuts out most of the light and is the coolest?

Silver tarps, because the silver is made with a black mesh inside of the material. The silver does not allow any light to pass through. White, red green, orange and yellow tarps are translucent. Light (not UV rays) will pass through. You will get the natural light. Our shade screen/mesh tarps has 73% shade protection and does allow water to pass through.

Are your tarps good with wind?

Yes, very much so, but we cannot guarantee against any type of weather related incidents. If you are in a windy area and you wish to tie your tarps to something, we recommend bungee cords with hooks which can be seen on our Accessories page.

How should I tie my tarps down?

We suggest using bungee hooks or bungee balls through the grommet. This assures flexibility and less stress on the material.

Can I use the canvas tarps for my canopy?

Canvas tends to expand and shrink in the rain and sun. We advise only using polyethylene for canopy top covers.

The tarp I received is 3 to 4 inches less on each side. What is a "Cut Size".

Cut size is the industry's standard way to measure. Cut size means the size of tarp is measured by the tarp fabric when the tarp is cut. After the tarps edges are folded and stitcked and tarp sections attached together to make the final tarp, some size eventually gets lost. For example, a 10 x 20 can be a (Approx.) 9'8" x 19'10".

What is the difference between a canopy and a tarp?

Canopy is a protective covering mounted on a frame with poles. A tarp is a material such as waterproofed canvas used to cover and keep valuables dry.

What are your tarps used for?

Our tarp covers have thousands of applications. Our tarps are used by farmers, schools, roofers for roof covers among many other uses.

What is Solution-Dying?

Denier

Denier is a unit of measure for the linear mass density of fibers. It is defined as the mass in grams per 9,000 meters, or 1 denier = 1 gram per 9 000 meters. Normally the higher the denier count, the higher quality of the tarp’s fabric mesh.

Cut size vs. Finished size

The cut size is the measurement when a tarp is cut at the beginning of manufacturing. It is like asking a tailor how much fabric is needed for a pair of pants. For example, a 12ft x 16ft cut size tarp means that when the tarp was initially cut at the factory, its size was 12 feet by 16 feet. However, when the tarp is finished, the size is normally slightly smaller. There are a number of reason why finished size is smaller. First, most finished tarp’s edges are folded over to form a double-layer reinforced edge. Second, a large piece of tarp may be made from multiple pieces of smaller tarps. For example, say the 12ft x 16ft cut size tarp is made from two 8? x 16 cut size tarps. The factory would have heat seal or fuse the two tarp into one. Finally, but very importantly, because poly tarp is a type of plastic fabric, a small but noticeable shrinkage comes when a poly tarp is folded. In the end, poly tarp’s finished size is approximately 6ft or up to 2% smaller than its cut size.

In US and Canada, a poly tarp’s size is most often stated as cut size and noted on the label. This includes tarps sold in all major home centers and retailers. So, it is very important you know exactly whether it’s cut size or finished size when you order your poly tarps from a supplier.

Difference between poly film and PVC film when packing food

Film can be made with different resins, each of which has a unique combination of properties that makes it idea for certain applications. For example, low density polyethylene (LDPE) film acts as a gas barrier, which is necessary for packaging such things as chicken, which would quickly spoil if exposed to oxygen. Polyvinyl chloride (PVC) film, is gas permeable and necessary for packaging such things as red meat, which requires a small amount of oxygen inside the package in order to remain fresh.
