This question certainly isn’t about fine homebuilding, and I hope no one minds the odd questions. That said…
A friend has some land on the Rio Grande that his family uses for hunting and fishing. The site floods every few years, but there isn’t much current over the property. They had a camp house, built as an unfinished shell, which survived the floods but was burned down last year. It’s likely that someone broke in on their way North and started a fire which got out of hand.
They’re planning to rebuild over the winter and their first choice was to pour concrete walls, but some of the family would rather have at least some insulation in the building. Can anyone suggest an inexpensive, durable way to insulate this place?
Also, how could they frame the roof to minimize the risk of fire damage in the future without having the place turn into a mess with the next flood? My suggestion was to cathedral frame the roof, use styrofoam to insulate and finish the ceiling with Hardipanel (the roof was and will be metal panels on stringers.) Can anyone suggest a better way?
