Patent ID: 8763330

Claim:
A system adapted and configured to ventilate thermal insulation in a roof structure of a building, comprising: a) a plurality of spaced apart rafters forming at least a portion of a roof structure; b) structural paneling material applied to the structure proximate an outer surface of the rafters, wherein an inner face of the structural paneling material defines an inwardly-facing interior building surface; c) thermal insulation material disposed between the rafters; and d) a spacer disposed along substantially the entire length of the thermal insulation material and interposed at least partially between the interior building surface and the thermal insulation material, the spacer acting to define a ventilation channel between the interior building surface and the thermal insulation material, the spacer having a body defining a plurality of openings therethrough, wherein the openings are adapted and configured to permit the transfer of moisture therethrough between the insulation material and air passing through the ventilation channel to facilitate the ventilation of the thermal insulation material, and further wherein the spacer includes an elongate generally planar body formed from a sheet of material defining a plurality of raised structures formed in the sheet material that act to separate the spacer from the interior building surface.
