These doors were installed in Duluth, GA. The doors are made of 25 gauge steel with windows and inserts. The arched inserts were chosen to play off the 45 degree corners. The interior photo shows the back of the door which is also steel. This door is double reinforced with steel on front and back with the insulation incapsulated in the middle. The spring system is high cycle torsion springs. You’ll notice a gap at the bottom of the door on the right which is due to uneven concrete. We cannot fix the concrete, but we did add a larger bottom seal to fill the gap.
Door: CHI 2283 W/ Windows and Inserts (Inserts give the design)
