Extruded acrylic sheets are a cost effective way to diffuse fluorescent light with bulb hiding qualities. Thicknesses* from: .020" to .250". Sheets can be custom cut to any size up to 54" x 108". Flat sheet thicknesses are measured from the peaks of the prisms not the valley’s. Some competitors will use a sheet that has had the valley’s ground out to save plastic. Be aware that not all flat sheets of the same thickness are of the same quality. Fluorolite only uses high quality sheets.
Acrylic: The industry standard. Excellent U.V. Resistance - Guaranteed not to yellow for 20 years. Good Shock Resistance.
Polycrbonate (G.E. Lexan ): Moderately U.V. resistant, Virtually Unbreakable, Handles Higher Heat Levels.
