The less bulletproof glass weighs, the cheaper the window frames are, as they have to support less weight. The same applies to transport and installation.
Bullet proof glazing with an area of approx. 1–6 m2 (10–60 sqf) can be produced particularly cost-effectively. From a glass area of approx. 6 m2 (approx. 60 sqf) the production costs usually increase, as handling is somewhat more complex. The same applies if the glass surface is smaller than approx. 0.5 m2 (5 sqf), as the setup costs per piece are spread over a smaller surface.
Bullet-proof glass with additional thermal insulation – with a low U-value – requires additional heat-insulating layers. This increases the prices by about 10–30%. The advantage: lower energy consumption of the building including lower heating costs.
If the bullet proof pane also reduces the sun’s heat entering the interior – solar control glass – prices increase by about 10–30% compared to a monolithic pane. In return, they save on operating costs of the air conditioning system.
The installation costs for bulletproof glazing depend on how good the accessibility is at the installation site: Is a large crane required? Can the bullet proof glazing be transported through the building? Is the load-bearing capacity of the floor sufficient and are the rooms large enough to transport the panes? The basic rule is: The lighter the bulletproof glass panes are, the more cost-effective they are to install.
