ABSTRACT:
A ventillating support upon which a roof insulation board can be rested to hold the board in spaced relationship with the roof deck and allow for an omnidirectional circulation of air to remove moisture that accumulates between the insulation and the deck. The device of this invention is a three-dimensional open-meshed rigid support made from intersecting sets of undulating elongated elements that are joined at their points of intersection. preferably the elements are flattened at those points where they will contact the insulation or the roof deck.
