Providing a clean aesthetic with a narrow sightline, the T Series Entrance Systems offer design versatility and thermal performance, exceeding U-factor requirements—with values as low as 0.43/0.45/0.48—for high-performing buildings, meeting stringent energy codes, and withstanding demanding conditions. The 25T (small)/35T (medium)/50T (wide) entrance doors are thermally broken with 6/6 nylon polyamide glass fiber reinforced bars, and a 1-inch insulating glass unit standard (up to 1 ¼-inch). Other features include 2-inch door leaf thickness, door corners that are mechanically joined/welded together, 10-inch bottom rails, seven options for mid-rails, and glazing options.
