US Patent:

7594362, Sep 29, 2009

Filed:

Nov 8, 2004

Appl. No.:

10/983984

Inventors:

John L. Sigmund - Holland OH, US
Thomas C. Gilbert - Clarklake MI, US

Assignee:

CertainTeed Corporation - Valley Forge PA

International Classification:

E04B 7/00

US Classification:

52 96, 52 94, 52 95

Abstract:

A ventilating component for a building, particularly a ventilating soffit, provides a high ratio of ventilation flow area to component coverage area. A sheet in a plane of coverage has a spaced-channel configuration, or alternatively a terraced configuration. Ventilation openings are placed in the connecting webs between the upper and lower levels, especially in sidewalls of elongated channels that open as slots on the exposed side of the soffit. These connecting webs are oriented at an acute angle relative to the coverage plane. In a channel arrangement the webs can be shaped to block direct view of the side walls. The acute angle precludes, or at least foreshortens, a view of the webs that contain the ventilation openings. The ventilation aspects are concealed while permitting a high ratio of flow area to coverage area.
