Adfors Clear Advantage? is the clear choice for high-visibility screen. Clear Advantage? screen features low diameter fiberglass yarns which, when combined with more yarns per inch, provides the optical illusion that the screen is invisible. As a premium screen product, Clear Advantage? is tested using ASTM D3656 standards. Adfors is also leading the industry by making our full line of fiberglass screen ortho-phthalate-free, ahead of industry standards.
