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

摘要

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.

主权项

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) 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.
