| CertainTeed has expanded the size range of New Castle XT™ DP50-rated windows, making it even easier for East Coast builders to meet homebuyers’ growing demand for larger windows while adhering to stringent building codes. CertainTeed’s DP50-rated windows are classified by the American Architectural Manufacturers Association (AAMA), meeting air, water and forced entry requirements as well as structural requirements as designated by AAMA 101 specification. In total, the expansion includes 24 new larger sizes that meet the DP50 structural rating, including windows as large as 36" x 80" for single-hung and double-hung, 72" x 76" for twin single-hung and double-hung, and 108" x 76" for triple single-hung and double-hung. “Builders along the East Coast who operate within strict building codes want to work with a company that offers large, well-designed windows that meet these codes,” says Maria McDonagh-Forde, Marketing Manager for CertainTeed’s Window Group. “CertainTeed now offers some of the largest DP50-rated windows available industry-wide.” Available in White or Tan, New Castle XT windows feature a fusion-welded sash and frame, a tilt-in sash for easy cleaning from inside the home and a balance system for trouble-free insulation. The windows come with a lifetime limited warranty and exclusive CertainTeed five-year SureStart™ protection for both materials and labor. |
