Call a local (or your nearest) metal building company. They can get you some
good panels. I would recommend a fiberglass R-panel. They come 3' wide x
whatever length you need. They are much stronger than Loxes or Homedepots.
And cheaper. I would hate to see someone waste money on the crap that the
lumberyards supply. I build steelbuildings and work with these things all
the time. They have a 10 year warrenty and I have seen them last for 20
years or more. Our supplier is M.B.C.I..They may have a warehouse near your
town. Im in Houston. And I think they will deliver for a fee. If you can
locate one near you it will save you money. If not the metalbuilding company
might jack up the price.
