Insulation spacer devices, methods and related construction techniques are provided. An exemplary device may include a body having a plurality of openings defining an openwork, to allow the passage of air therethrough when placed in contact with insulation material. The device may further include a plurality of spacer struts and/or spacing depressions fixedly attached to the body. The struts may be configured to maintain a predetermined distance between a first side of the insulation material and a building surface. The body and struts act together to define and maintain a space between the first side of the insulation material and the building surface, for example, for ventilation. The building surface can be the bottom face of a roof, an insulated attic floor, wall sheathing or a soundproofed demising wall, for example. The spacer device can be capable of being transported and stored together with, or as a separate item from, the insulation material, and can also be stored in nested layers. The device can also be stored in rolled form. The openwork of the device can additionally or alternatively include a sheet of Entangled net filaments or other similar material.

What is claimed is: 1. 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) sheathing material applied to the structure proximate an outer surface of the rafters, wherein an inner face of the sheathing 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. 2. The system of claim 1, wherein the spacer includes a body and a plurality of struts extending from the body along the length of the body, the struts acting to separate the spacer from the interior building surface. 3. The system of claim 2, wherein the struts are deployable from a first condition wherein the strut is substantially parallel to the body to a second condition substantially perpendicular to the body. 4. The system of claim 1, wherein the spacer includes: a) a longitudinal gridwork body having a plurality of openings defining an openwork to allow the passage of air therethrough when placed in contact with the thermal insulation material; and b) a plurality of struts extending from the gridwork body, the struts being configured to maintain a predetermined distance between a first side of the insulation material and the interior building surface. 5. The system of claim 1, wherein the spacer includes: a) a longitudinal generally planar body having a plurality of openings defining an openwork to allow the passage of air therethrough when placed in contact with the insulation material; and b) a plurality of depressions defined in the generally planar body, the depressions being adapted and configured to maintain a predetermined distance between a first side of the insulation material and the interior building surface, the body and depressions acting to define and maintain a space between the first side of the insulation material and the building surface. 6. The system of claim 5, wherein each depression defined in the generally planar body of the spacer is defined by a plurality of struts, each strut having a first end and a second end, the first end of each strut being connected to the planar body and the second end of each strut being connected to a generally planar land. 7. The system of claim 1, wherein the spacer includes a plurality of barbs for anchoring into the thermal insulation material. 8. The system of claim 1, wherein the spacer includes a body made from strands of polymeric material defining openings therethrough to permit the passage of moisture to facilitate the ventilation of the thermal insulation. 9. The system of claim 8, wherein the spacer is made from entangled strands of polymeric material. 10. A system adapted and configured to ventilate thermal insulation in a wall structure of a building, comprising: a) a plurality of spaced apart studs forming at least a portion of a wall structure; b) sheathing material applied to the structure proximate an outer surface of the studs, wherein an inner face of the sheathing defines an inwardly-facing interior building surface; c) thermal insulation material disposed between the studs; 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. 11. The system of claim 10, further comprising: a) a first opening defined in the building structure proximate the bottom of the studs to permit fluid communication between the ventilation channel and air outside the structure; and b) a second opening defined in the building structure above the first opening to permit fluid communication between the ventilation channel and air outside the structure, wherein the first opening, second opening and ventilation channel cooperate to permit air outside the structure to circulate into and out of the ventilation channel to facilitate ventilation of the thermal insulation material. 12. The system of claim 10, wherein the spacer includes a body and a plurality of struts extending from the body along the length of the body, the struts acting to separate the spacer from the interior building surface. 13. The system of claim 12, wherein the struts are deployable from a first condition wherein the strut is substantially parallel to the body to a second condition substantially perpendicular to the body. 14. The system of claim 10, wherein the spacer includes: a) a longitudinal gridwork body having a plurality of openings defining an openwork to allow the passage of air therethrough when placed in contact with the thermal insulation material; and b) a plurality of struts extending from the gridwork body, the struts being configured to maintain a predetermined distance between a first side of the insulation material and the interior building surface. 15.
