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 building structure comprising: a) a plurality of spaced apart, vertically oriented studs; b) sheathing material applied to 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 device interposed between the interior building surface and the thermal insulation material, the spacer device acting to define a vertical ventilation channel between the interior building surface and the thermal insulation material, the spacer device being adapted and configured to allow the passage of air through the vertical ventilation channel and having a body defining at least one opening therethrough that is adapted and configured to facilitate the transfer of heat and moisture therethrough between the insulation material and the air passing through the vertical ventilation channel; e) 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 f) 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. 2. The system of claim 1, wherein at least one of the first and second openings includes a screen to prevent the passage of unwanted material into the ventilation channel. 3. The system of claim 1, wherein at least one of the first and second openings includes a damper that can be displaced from a closed position to an open position to permit the passage of air into the ventilation channel. 4. The system of claim 3, wherein the damper is adapted and configured to selectively prevent cold air from entering the ventilation space. 5. The system of claim 3, wherein the damper is biased in a closed position. 6. The system of claim 5, wherein the damper is biased in a closed position by a thermostatic spring. 7. The system of claim 5, wherein the damper is biased in a closed position by a weight. 8. The system of claim 1, wherein the second opening is located proximate the top of the studs. 9. The system of claim 1, wherein the second opening is a soffit vent. 10. The system of claim 1, wherein the second opening is a ridge vent and the ventilation channel passes through the wall structure and roof structure of the building structure. 11. The system of claim 1, wherein the spacer device acts to at least partially displace the insulation material away from the sheathing. 12. The system of claim 11, wherein the first opening is proximate the foundation of the building structure. 13. The system of claim 1, wherein the ventilation channel in the wall of the building structure spans at least two stories. 14. The system of claim 1, wherein at least one deployable fire stop is disposed inside the ventilation channel, the deployable fire stop being adapted and configured to block off the ventilation channel during a fire. 15. The system of claim 14, wherein at least one deployable fire stop is an intumescent fire stop that is thermally activated. 16. The system of claim 15, wherein the intumescent fire stop is substantially strip-shaped. 17. The system of claim 1, wherein the lower ends of the studs are cantilevered over an outer edge of a floor platform to provide a space for the ventilation channel alongside the floor platform. 18. A method of constructing a multi-level building, comprising: a) constructing a first level of a structure using a plurality of spaced, vertically oriented studs, wherein a portion of the ends of the studs are cantilevered over the edge of the floor platform of the building; b) applying sheathing to an exterior face of the studs to form an exterior wall; c) disposing an insulation spacer defining a plurality of openings therethrough along its length proximate an inner face of the sheathing between adjacent studs; and d) disposing thermal insulation proximate the insulation spacer between the studs, wherein the insulation spacer cooperates with the thermal insulation and the sheathing to define a vertically oriented ventilation channel between the studs to facilitate heat and mass transfer through the insulation spacer between the thermal insulation and the air channel, wherein the ventilation channel is in fluid communication with air outside the structure by way of a first opening proximate a first end of the ventilation channel and a second opening proximate a second end of the ventilation channel to permit air outside the building to circulate into and out of the ventilation channel to facilitate ventilation of the thermal insulation. 19. The method of claim 18, further comprising disposing a damper proximate at least one of the openings that can be displaced from a closed position to an open position to permit the passage of air into the ventilation channel. 20. The method of claim 19, wherein the insulation spacer is positioned in a manner to at least partially displace the insulation material away from the sheathing. 21. The method of claim 18, further comprising disposing at least one deployable fire stop inside the ventilation channel, wherein the fire stop is adapted and configured to block off the ventilation channel during a fire.
