Insulated Wooden Gateway

Description
The best battle, as they say, is the one you never have to fight. With formidable enough gates, the enemies will think twice about attacking any fortress. Not simply because the scale of the gates has them concerned about getting inside, but because large gates imply large inhabitants and armies get nervous when they think they might be outnumbered. Built of planks coated in resin for insulation, reinforced by wooden slats that have been shaped to fit, this will provide a safe haven from the weather and strong front to any foes who come knocking.
