Metal Foam Turfs
Created by: Shadowmech88
All metal foam reactions now create a metal foam floor if they are on a space turf. Metal foam floors are airtight, but they're flimsy and can be broken through with pretty much any tool. However, they can still serve as a quick patch for a breach, and you can build lattice and plating over them, allowing you to patch a hole without re-opening the breach.
Metal foam reactions made with aluminum no longer produce metal foam walls. If you want to make metal foam walls, you can still do it by using iron instead of aluminum. Metal foam walls will still have metal foam floors underneath them if they were created on a space turf.
