	Green - All blocks under this designation are capable of being airtight (pressurized). Some blocks may require certain orientation to allow for a seal. Others blocks (such as windows) may require other blocks to seal. However, the block itself is airtight.
	Red - All blocks under this category cannot seal a room, no matter the orientation. Some may appear to fill an entire block space, but they will not seal the room.
