Rigid Insulation<br />
Numerous types of rigid insulation are now in<br />
use, <strong>and</strong> may be made from exp<strong>and</strong>ed<br />
polystyrene beads, rigid urethane laminate,<br />
low density fiberboard, or from fast-setting<br />
liquids poured on-site. They vary in thickness<br />
up to more than 2" <strong>and</strong> in length <strong>and</strong> width<br />
depending upon the manufacturer. All these<br />
types are efficient insulators <strong>and</strong> are usually of<br />
sufficient density to hold the weight of a<br />
normal roofing material without the need for<br />
lumber bridging. If you live in an area where<br />
snowfall is prevalent, please consult your local<br />
building official for snow load requirements.<br />
