Phifer offers a complete selection of fiberglass insect screening. BetterVue and UltraVue are Phifer’s new iVis (improved visibility insect screening) products that allow you to “see the view, not the screen.” Phiferglass, Phifer’s trademarked fiberglass screening, has been the standard in the industry for decades. All three products are woven from permanent glass yarn, which has been coated with a protective vinyl to ensure lasting beauty, color and flexibility and will not rust, corrode or stain. They are produced under the most exacting conditions to meet rigid specifications and have all passed 1200 hours of QUV accelerated weathering. BetterVue and UltraVue are GREENGUARD® indoor air quality certified.
