Strengthened Glass Window
The Strengthened Glass Window is a metal and glass plate that affixes to a window frame opening to allow players to see in and out of it while prohibiting anyone from using it as an access point. They are available to be researched by all players as a tier 2 workbench blueprint.
It may be picked up with a Hammer at the cost of half of its default durability. The field of view on the Strengthened Glass Window is considerably larger than the more defensive Reinforced Glass Window.
The primary utility of the Strengthened Glass Window is to safeguard a potentially vulnerable access point on a base that utilizes a window frame. It is the second-best window cover for offline unlootable loot room coverings, shooting floor windows that you want available but not immediately accessible, and electrical room components and TC access. While coming in second for strength, it may be bolstered when paired with either available embrasure.
Strengthened Glass Windows are found in mid-to-higher tier crates and dropped from a wide range of scientists. They do add upkeep costs to bases that use them and will remain in place without decay so long as they are under the effect of a Tool Cupboard.
