Hi all,We have a roof made of steel I-beams supporting flat bricks, with interlocked barrel tiles on top, Spanish-style.I'm building out the room underneath to be a bathroom and insulation is key.However, I'm not sure I can safely drive fasteners into the flat bricks (e.g. to secure insulation and/or joists) and I'm not sure there's a great way to attach anything to the steel beams…Here's are some photos of the roof and rough schematics of the construction: http://ift.tt/2idPOGU guidance on how I can attache insulation to this roof? Are there any extra concerns I should be aware of about this being a bathroom (e.g. condensation on the I-beams)? via /r/DIY http://ift.tt/2xH5JPZ
