ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to the field of metal building construction. More particularly, this invention relates to means and methods for insulating a space adjacent the exterior skin of a metal building.
Metal buildings are known for their durability and low exterior maintenance requirements. However, because of the high thermal conductivity of their metal components, fasteners and connectors, metal buildings are difficult to effectively insulate. The energy costs involved in heating and cooling a metal building can be relatively high. A considerable amount of thermal transfer takes place at the metal walls, and even more thermal transfer typically takes place at the ceiling or metal roof of the building. Conventional efforts to insulate metal building ceilings typically involve placing a layer of insulating material over the top surface of the upper flange of a purlin. Then the roof deck is attached to the upper flange of the purlin. This squeezes the insulating material above each purlin and results in a considerable R-value reduction and energy loss in those regions. The initial installation is done from the outside of the building by relatively highly paid steel workers, weather conditions permitting. The work can often be dangerous and difficult to do in windy or wet conditions.
Additional insulation can be added later from the inside by placing batt or blown insulation inside a flexible netting or fabric that is draped from the purlins. However, such insulated ceilings are not very energy efficient and cannot be washed when the fabric or insulation begins to discolor or get dirty. A low cost, energy efficient and reliable method of providing a well insulated washable ceiling or wall in a metal building is needed.
Therefore, a primary objective of the present invention is the provision of an improved insulated ceiling or wall for a metal building.
Another objective of this invention is the provision of improved methods for insulating a ceiling or wall of a metal building.
Another objective of this invention is the provision of an improved means for insulating a ceiling or wall of a metal building.
Another objective of this invention is the provision of an insulated ceiling that has a higher R-value than conventional ceilings due to thermal isolation of metal components and reduction of the total area where high thermal transfer can occur.
Another objective of this invention is the provision of a method of insulating a ceiling that can be done completely from inside the building once the roof has been installed.
Another objective of this invention is the provision of an insulated ceiling that provides a more effective moisture barrier.
Another objective of this invention is the provision of an insulated ceiling that is washable from inside the building.
Another objective of this invention is a provision of an insulated ceiling that is easy to install, attractive, energy efficient, durable and reliable in use.
These and other objectives will be apparent from the drawings, as well as from the description and claims that follow.
SUMMARY OF THE INVENTION
The present invention relates to means and methods for providing an insulated ceiling or wall. This invention is especially useful for insulating the ceiling of a metal building. The method of forming an insulated ceiling includes attaching an insulated panel to the lower flange of the purlins to form an insulatable space between the panel, the purlins, and the exterior skin of a building. The space is then filled with insulation material.
An insulation delivery system is provided for the filling process. This system is especially well-adapted for use with loose-fill insulation material. The delivery system includes a blower connected to a source of blowable insulating material, and a special manifold connected to the blower and adapted to deliver the material into the space. The manifold has a manifold plate that is slidingly insertable in the space. The manifold plate includes a peripheral seal and at least one air hole therethrough so that air can escape the space while the insulation is being blown in. The manifold allows the space to be filled with insulating material to a desired density or R-value.
The manifold plate can be formed in two or more slidable sections so as to be adjustable in length in at least one direction. The number and location of the air escape holes can be selected to achieve the desired results.
