   35 tons / square meter = ~45 lbs per square inch @ 800 degrees

   Impressive. I wonder how the steel Velcro gets attached.

   You screw down your shingles?

   Oh, must be those 1-1/4" GRK cabinet screws with the washer heads and Climatek coating..... ;^)

   several of the old barns around here have shingles put on with wooden pegs.  Still in place when the foundation or timbers rotted out. Over 100 years later!

      I wouldn't even want to think about the time that took.

   It obviously worked!

   I might have a hard time selling the technique, first to the customer, then the BI.......

   There is a old, very exclusive, country club here with a hardwood ball room floor which is fastened with "butteryfly biscuits".  Flooring is about 6" wide --- thousands and thousands of hand cut joints to accept the biscuits, ~24" apart on edges plus one at each butt joint......

   I don't know the proper name of the joinery technique.  The biscuits look like a butterfly or back to back dovetail.

   Flooring is maple, biscuits are mahogany. When you walk across the floor it has a slight "hollow" sound - I get the impression it is one of the original floating floors.

   Beautiful.

   Same country club has a roof which is covered in 1" inch thick slate - still planar as can be - I always wanted to go into the attic to see the framing underneath of that!

   Of course, the Velcro adhesive will give way long before that load is reached, unless you attach the steel Velcro with steel screws.
