They can be used in Space Hulk, but I also plan to use them for doors on Science Fiction 2.5D terrain tiles. I want to make terrain tiles for games like Sedition Wars and Imperial Assault, and eventually they will see use in my Aliens/Colonial Marines games.
And Thank You for making something I actually need. I thought the doors might be useful at first glace. But when you showed how to make the double sided doors, they became a must.
