I have previously BLOGGED about the use of Lightweigh Construction material in home construction. Just last month at the end of JUNE 2012 an emergency Response Worker was killed due to the collapse of a structure made of LIGHWEIGHT CONSTRUCRTION MATERAIL. Here is the link too the story.

Chilling.....to think that there cannot be a standard established too mandate some type of marking on the exterior of the building too notify the responding crews that the structure is made of lightweight material and failure of the building is more likely too happen suddenly then older convential building materials used from solid #1 Southern Yellow Pine and a minimum of 2x12 with a burn thru time of about 90 minutes too what is currently being used and open web floor truss with a burn thru time of about 15 minutes or less for floor failure.
