Transcend Series doors feature an insulated barrier within the frame that reduces heat conduction through the door’s metal framing. The Transcend Series features thermally broken technology that prevents deterioration caused by condensation and the lowest U-Value for energy loss. Its efficiency for water infiltration is zero leakage at a 1.0 psf pressure differential at over 300 gallons per hour. The series offers improved heating and cooling costs with a fully-glazed door and frame using 1" low-E insulated glass. Its overall NFRC U-value greatly surpasses the current energy requirement of .77, and its higher condensation resistance factor reduces interior frost build-up. Transcend Series thermally broken entrances meet or exceed all American Society for Testing and Materials (ASTM) standards while remaining customizable. Its innovative, beautiful, and functional construction aids building performance, while its fully-assembled construction saves time and money on installation. Transcend Doors also come with a manufacturer's warranty, with swing doors offering a five-year warranty and balanced doors offering a 10-year warranty.
