Insulation and ventilation systems for building structures

An insulation and ventilation system for a building envelope, the system comprising:

• one or more interior building envelope layers;
• an insulation panel having an interior side abutting against at least one of the one or more interior building envelope layers and an exterior side having a plurality of transversely spaced and continuously longitudinally extending grooves interspaced between a plurality of transversely spaced and continuously longitudinally extending protrusions, the continual longitudinal extension of the grooves and protrusions orthogonal to the transverse spacing of the grooves and protrusions;
• and
• one or more exterior building envelope layers located exterior to the insulation panel to provide a plurality of transversely localized venting channels defined at least in part by an interior surface of the one or more exterior building envelope layers and the grooves of the exterior side of the insulation panel;
• wherein the one or more interior building envelope layers comprise a plurality of studs and wherein an insert member is inserted in at least one of the grooves which is aligned with the studs.

A method for providing insulation and ventilation in a building envelope, the method comprising:

• providing an insulation panel having an interior side and an exterior side having a plurality of transversely spaced and continuously longitudinally extending grooves interspaced between a plurality of transversely spaced and continuously longitudinally extending protrusions, the continual longitudinal extension of the grooves and protrusions orthogonal to the transverse spacing of the grooves and protrusions;
• abutting the interior side of the insulation panel against an exterior surface of one or more internal building envelope layers;
• and
• mounting one or more exterior building envelope layers at locations outward of the insulation panel to thereby provide a plurality of transversely localized venting channels defined at least in part by an interior surface of the one or more exterior building envelope layers and the grooves of the exterior side of the insulation panel;
• and
• inserting each of a plurality of transversely spaced apart and longitudinally extending insert members into a corresponding one of the grooves.
