Where to obtain Materials

Although leather aviator type hats work the best because they cover the whole head and enable tape to secure the Velostat, almost any type of hat that holds eight sheets of Velostat over your head will work.

You can also sew the Velostat to a cloth hat by using a sewing needle for leather which can be purchased at a fabric shop. Large hats with a band on the inside make good thought screens because all you have to do is cut and insert the Velostat into the inside hat band. You can then sew or tape the Velostat to the hat band.

Contact this website if you need directions for making thought screens from other types of hats.

Tape can be purchased at any hardware store, 2 inch wide tape is recommended. Suggested tape is Nashua All-Weather Duct Tape, part number 398 HVAC. If you use duct tape, try to purchase a professional grade duct tape, which has better adhesive and is stronger than cheap duct tape.

Michael Menkin holds a 150 foot long, 40 pound roll of Velostat which costs $200. Some suppliers sell Velostat by the yard for a good price. Shop around for the best deal.

Michael Menkin is 6 feet two inches tall and weighs 215 pounds. He is a college graduate, honor student, former military officer, and a technical writer.



Velostat is now sold by DESCO products.

Most suppliers only sell Velostat by the 150 foot roll. Some suppliers may sell Velostat by the linear foot or yard. You must contact individual suppliers to determine if they sell Velostat by the linear foot or yard.

DESCO sells velostat but they still use the 3M part number 1704, 1706, or 1708.

Purchase a minimum of 3 linear yards if you are using 4 mil Velostat. It's a good idea to purchase an additional yard of Velostat just in case you make mistakes. If you use 4 mil Velostat, part number 1704, you must use 12 sheets for an effective thought screen.  If you purchase 6 mil Velostat part number 1706, you need two linear yards for 8 sheets.  If you purchase 8 mil Velostat, part number 1708, you only need a yard and a half for 6 sheets.  Part number 1708 is thicker and harder to work with - and to sleep with.

To purchase Velostat in your area search the internet by entering DESCO Products into a search engine or look in the yellow pages of your local phone book under Electronic Equip & Supls - Whsle & Mfrs  (Electronic Equipment and Supplies, Wholesale and Manufacturers).  You cannot purchase velostat in a hardware store or an electronics store.

You can get different sizes, lengths and thicknesses.  Part 1706, 36" X 150' is recommended.
