How much heat can the curtains endure?

Akon sells a variety of materials. Standard clear 20mil vinyl material and 13 and 18oz vinyl materials are rated for 140 degrees Fahrenheit. However, if you have an application where 140 degrees of heat is present then the curtains can and will eventually fail.
The best example is an engine running with your foot all the way to the floor on the pedal. You are running it at its maximum ability and it will eventually fail. The same is true for using curtains at their max temp rating. They will last, but there is no way to guarantee how long. The material becomes very soft and grommets can pull out or rips can occur.
If you need high temperature rated curtains then view our line of heat resistant industrial curtains.

Should the length of curtain match track length on a rolling curtain? Or is extra length better?

When getting a quote on a curtain, we need to know the actual distance you are covering. We will then quote 5% more for proper drape. The track will match your actual distance you are trying to cover.

Are the curtains easy to clean?

All of the Vinyl curtains are very easy to clean. They are a slick material that makes them ideal for washing down. Much like a shower curtain, the slick surface does not easily allow debris to stick to it.
To clean your industrial curtains, you can use a cleaning product called “Simple Green”. This cleaning material will not harm the PVC vinyl that your curtains are constructed from. Please know you should never use a solvent based cleaner. A solvent based cleaner can damage the vinyl material. You can use a mild non-abrasive detergent if you have excessive greasy or oily type of film on the curtains.
It is a good idea to test a small piece of the curtain with the cleaning agent first before starting the entire cleaning process.
Please note any material that may be quoted and or sold which is “canvas”, “heat curtain material”, or “fabric” will have special cleaning needs. Please ask your sales person.

How much wind can the curtains endure?

There is no exact answer for this as variables such as wind speed, the curtain size, and attachment points all play a key role in stability. However, small curtains can handle a fair amount of wind while large curtains cannot. Please remember that these curtains once erected act as large sails which produce a tremendous amount of stress on their attachment points. Basically, all manufacturers will inform you that their curtains are designed to block the breeze but can get damaged in strong winds. If you have wind speeds above 19-24 mph, it is best to retract the curtains and let the wind blow through to prevent damage. If high winds are going to be present then please inform us before your curtain is produced so we can reinforce critical components.
Curtain Track Hardware will ensure you have the ability to retract the curtains in high winds. If a fixed curtain is a must then you should reinforce it with our pipe-staff hardware or purchase aircraft cables which can reinforce the curtain when the wind blows.

Do all of the curtains have grommets?

Yes, all curtains come with grommets spaced on 12″ centers unless you specify on your request that you do not want them. We can also add them to all edges if requested.

What does “MIL” and “OZ” mean?

  • A “mil” is a unit of length equal to 0.001 of an inch (0.0254 mm). Mil is used to measure the thickness of materials such as Vinyl Curtains. As a general rule, the thicker the mil / curtain the better quality.
  • An “oz” is the weight of the material per square yard. As a general rule, the more ounces equals a better quality of curtain.

How much cold can the curtains endure?

Different materials have different low temperature ratings. These are very important so please read carefully.
Clear Curtains – 20 Mil Clear and Clear Vision Panels – Ideal for temperatures going as low as 10° F or -12° C and above. If folded below these temperatures or blown around in the wind the vinyl will likely crack. If your environment is likely to have temperatures below this range it is best to use only opaque solid color curtains.

Opaque Solid Color – 18 oz Coated – Ideal for temperatures going as low as 0° F or -17° C. If folded below these temperatures or blown around in the wind the vinyl will likely crack. If your environment is likely to have temperatures below this range it is best to use our 22 oz curtains.

Opaque Solid Color 22 oz Coated – Ideal for temperatures going as low as -22° F or -30° C. If folded below these temperatures or blown around in the wind the vinyl will likely crack. If your environment is likely to have temperatures below this range it is best to not use our curtains.

Installation in cold temperatures and windy conditions is not recommended. If it must be installed in these conditions, treat the curtain with care. Try your best not to put too much stress on any one point and try your best to keep the curtain from flapping or whipping in the breeze.

Can you field cut the curtains to get around obstructions?

Yes, you can cut the Vinyl curtains in the field. This is common and is typically needed for a static curtain that need to go around obstructions. The curtains are reinforced with an internal scrim to prevent run away tears. Once you cut the curtain, you can then use a clear patch tape called www.Tear-Aid.com to patch it back together. You can purchase this directly from their website or other places on the internet. The tape is made for Vinyl and is extremely strong.
