Glass and aluminum door hardening is reinforcing various parts and components of the door, including installing additional hardware, to ensure immunity to kick-ins and decrease susceptibility to a variety of other break-in methods.
For glass and aluminum doors we recommend installing doors that swing out and come with 5" wide stiles, for rigidity. Additionally, the door should have three 12" crossmembers, a surface-mounted full door hinge, a full length latch guard to cover the gap between the door edge and the jamb, and a grade 1 door closer. If the door is a Means of Egress, then we recommend a grade 1 panic exit bar or a grade 1 electric strike. Otherwise, the door needs a grade 1 deadbolt.

We design aluminum and glass doors differently than traditional aluminum and glass doors. The "stile" is the name of the vertical side of the frame of the door. "Rails" is the name of the horizontal cross pieces of the frame of the door Traditional 2" wide stile doors are very weak and flexible. and they tend to have very small rails. We use a 5" wide stiles and we use very large rails - we even add a 3rd rail in the middle of the door as a "bellyband" This is where we mount the panic exit bar (lock). These over sized stiles and rails greatly increase the rigidity of the door.
The full length hinge covers the door gap on the hinge side of the door, from the top of the door to the bottom. This provides a barrier to some one trying to pry the with a crow bar from the hinge side. Full length hinges are also better than regular hinges in that they are much stronger and thus better at keeping a heavy door aligned and working properly.
Grade 1 dead bolts are designed and tested (by BHMA) to with stand significantly more powerful blows (meaning kicks or blows from a sledge hammer) than a grade 2 or grade 3 deadbolt. A grade 1 deadbolt has to withstand 2 blows at 60lbf, 2 at 90lbs and 2 at 120lbs, where as a grade 3 only needs to withstand 2 blows at 60lbf. Also, the bolt is tested to 1200 lbf of pushing force as opposed to only 600 lbf.
Panic exit bars are required when a room or building reach a specific occupancy. A panic bar exit device allows for the door to open just by pushing against it. So when a crush of people push the first person against the door the door swings open reducing the risk of injury to the first arrivals.
Consistent, effective closing and latching is the purpose of a closer. Grade 1 closers meet ADA requirements for door opening resistance pressure while still providing for consistent closings. Grade 2 closers do not meet the stands consistently.
A full length latch guard covers the gap from the top of the door to the bottom and makes it very difficult to pry open the door, even with a 36" crowbar. The quality of the latchguard is very important. Short 12" ones are very ineffective.
