摘要:
A method of predicting and communicating transient hygrothermal behavior of an installed building component in a building wherein an interior environment of the building is materially affected by an environment exterior of the building, includes: defining a performance characteristic of the building component that is affected by transient hygrothermal behavior of the building component; defining exterior and interior climatic factors that affect the defined performance characteristic wherein the interior climatic factors are a function of the exterior climatic factors; and defining one or more non-climatic factors that affect the defined performance characteristic. Inputting these factors into a transient hygrothermal simulation software program to create a software model for performing simulations which predict changes in the defined performance characteristic, as a function of time, that are compared with a threshold performance characteristic value, to provide a user guide.

Embodiments of the invention provide methods and systems for insulating a cavity of a structure. A system may include an insulation machine having an insulation blower that blows insulation into the cavity and a hose having a lumen throughwhich the loose fill insulation is blown. The system may also include a cover positionable atop the cavity of the structure. The cover may include an aperture throughwhich the distal end of the hose is inserted to blow the loose fill insulation into the cavity and an electrically conductive material or layer. The electrically conductive material or layer may electrically contact the hose when the hose is inserted through the aperture. The system may further include a ground wire electrically coupled with the cover to dissipate a charge from the hose by providing an electric path for the charge.

A method of applying dry and substantially thermal and acoustical insulation by spraying an air entrained stream of high velocity pils into cavities, including vertical wall cavities, without having to use any insulation securing means is disclosed. A nozzle system is used that comprises a shredder section for reducing the size of the pieces of insulation to pil size and an accelerator section for increasing the velocity of a stream of air suspended pils for improved just-installed insulation integrity or strength.

摘要:
Nozzles for converting clumps and nodules of dry or substantially dry fibrous insulation to pils and for spraying on the so treated and accelerated air entrained insulation pieces to form thermal and acoustical insulation in building cavities. The nozzles comprise a shredder section for reducing the size of many of the pieces of insulation to pil size and an accelerator section for increasing the velocity of a stream of air suspended pils for improved just-installed insulation integrity or strength. The shredder and the accelerator can also be combined in a single unit.
