In a split second, the insulation carbonized, and a plasma arc flashed, reaching temperatures hotter than the surface of the sun. The dry timber frame caught fire instantly. By the time the smoke alarm screamed, the wall was already engulfed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This isn&#8217;t a movie scene.
