4' X 6' or 4' X 8' 1/4"-1/2" Temperboard or any smooth, non-conductive surface works great. Sheet metal is also great. Position 2 - 4' panels into a 90 degree L and curtain a 30" door way. Pin the Ls to create booths 6 1/2 foot wide by 8 or 10 feet high, the depth can be ?. Leave or frame the sides so there is 18 - 24 inches from the floor. Great vent enhancer. Don't paint it black. Paint the surfaces with a flat non reflecting latex paint. White is great but get creative, a light blue, green or yellow or shades thereof. Don't worry about it getting dirty. Soap/detergent cleanser and water clean up or just repaint it. Put color combinations together so that you don't have a sterile institutional type paint job. The flexible see through curtains are great for the fronts. Paint panels to match/coordinate the curtain colors. Need help with color combinations, a schools interior design/decorating class/instructor is a great resource. If you want to do it up big, have the design class paint a mural or so depicting welding/layout in action. Yes, there are facilities that use 1/8 -1/4" 4' X ? or 5' X ? ASBESTOS. They shall remain anonymous.
