I inspected a new construction home inside Houston today. Single family home with less than 5 feet separation to a twin house on the divided lot. The house was advertised as having cement fiberboard siding, but it turned out to be sided with LP Smart Lap Siding
For houses with less than 5 feet separation the walls are required to meet “1 hour-tested in accordance with ASTM E 119 or Walls UL 263 with exposure form both sides”
Does anyone know if LP Smart Lap Siding meets this standard? I have not found anything saying it does, but the LP customer desk is closed and don’t want to jump to conclusions. The city green tagged it, but they might well have thought it was cement fiberboard and we don’t rely on city inspectors anyway. This could be a big issue for the builder if the siding does not meet the requirement.
