Abstract

An insulated roof structure includes insulating thermal elements which space attachment clips from an underlying purlin and introduce substantial thermal resistance above the purlin. Each insulating element includes a metal cap and an insulating body portion. The cap is enlarged at one end to overlappingly receive the end of an adjacent insulating block. And, the cap has a positioning device that aids accurate positioning of the overlying roof panels.
