I want to talk today about our 4000 series products. Are you needing a high performing, thermally broken window but need one that is rated at a class C instead of a HC or AW rating? Tthen look no more. Our 4000 series is the perfect fit for your project. It is a 3 ¾” system and is available in a single hung, double hung and fixed configurations. The single hung 4050 has a C55 rating, the double hung 4000 has a C50 rating, and the 4100 fixed window has a rating of HC70. The 4000 series has full receptor system available as well as internal reinforcing options if needed for your projects. The operating sashes incorporate marine type glazing. This system is only sold as factory glazed. If you need additional assistance please contact us at 800-668-1645 ext 174 or visit our website at www.ccbpwin.com for downloadable details, specifications, and test reports.
