| School windows resist vandalism without metal screens  When officials at the Dutch Broadway School in Elmont, NY considered updating their old windows, they wanted a glazing material that would give them long term resistance against vandalism and the effects of outdoor weathering. They also opted for maintaining an open environment without the enclosed feel of metal grill-work, often used to protect window systems. The solution came from Architectural Window Manufacturing of Rutherford, NJ. The company upgraded the school's old windows with a new long-life polycarbonate-based glazing material designated Makrolon MAK 15.Sheffield Plastics, a Bayer Material Science LLC company, produces the new clear sheet. A recent technological advance allows the manufacturer to back the product with a warranty against the effects of weathering for 15 years, up to twice that of prior coated polycarbonate sheet materials. Warranted against breakage as well, Makrolon MAK 15 also provides unobstructed views by eliminating the need for protective secondary metal grilles. Makrolon MAK 15 sheet is available in standard glazing sizes and thicknesses. Following its recent introduction, it has been used as a direct replacement for glass, and also as over-glazing on existing window systems both for damage resistance and added energy efficiency. write your comments about the article :: © 2010 Construction News :: home page |
