Devices and methods to provide air circulation space proximate to insulation material
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.

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.
9. The system of claim 7 , wherein at least some of the raised structures define at least one opening therethrough to facilitate ventilation of the insulation.
10. The system of claim 9 , wherein the raised structures that define at least one opening therethrough include a planar land displaced from the body connected to the body by a plurality of struts.
