Wood Window

Description
A  is a craft-able item. Once placed it can be upgraded up to four times with an upgrading tool. The first three levels of upgrade require 10x Wood each. A is now a part of the new Upgrade path since A13 and can be upgraded all the way to a steel  window plug now with the correct materials. A  is currently the only upgradable window that can be crafted by the player; it makes an excellent armored skylight for a fortified garden.

Crafting
You can craft a by searching for it in your crafting window search bar, or by clicking on the ingredients, selecting recipes, then selecting.

Note

 * A  drops three Broken Glass upon destruction, making broken glass a renewable resource.
 * Glass Panes are not needed to craft this.
 * Despite using two pieces of Wood to upgrade, only one plank appears to be added to the window.
 * A  cannot be placed if surrounded on all sides by other placed windows.
