Loosen the screws on the sides of the solarium door’s metal frame with a Phillips screwdriver. Remove all of the screws that hold the window in place. This will loosen the frame around the solarium glass door.
Lift out and remove the broken or cracked glass from the window and set it aside.
Slide the new glass into the metal frame by slipping it into the bottom part of the frame first. Move the glass to the left then the right to fit it into the sides of the frame. Finally, snap the top of the glass into the upper part of the frame.
Tighten the screws around the new glass in the solarium door.
