Benefits of technology

[0005] Ridge vent venting area, known as NFA (“Net Free Area”) is calculated by adding up the sums of all louver openings. Generally, higher NFA values are desirable. The shortest distance between two points is a straight line. Therefore, by using a chevron or curved profile, the line between two points can be extended. Thus the increased surface area of the rib structures will offer greater NFA values within a given space. Increased NFA from a given louver section could be used to produce a nail gun version of rigid and roll vent designs. A lower profile of parts will have fewer louver openings and a lower NFA rating than the standard hand nail version. Increasing the louver rib lengths and NFA per opening will permit lower profile design to have a more desirable NFA.

Problems solved by technology

Such ventilation prevents undue heat buildup, which can render the living quarters of the building uncomfortable and impose unreasonable energy requirements for cooling.

Embodiment Construction

[0010]FIG. 1 illustrates one embodiment of the present invention. A ridge vent panel 10 is shown from a top view perspective. At side wall edge 12 of panel 10 are a plurality of louver ribs 14 having a chevron configuration. As illustrated, chevron-shaped louver ribs are horizontally layered, however the invention is not limited in this respect and the invention contemplates other configurations such as vertically arranged chevron-shaped louvers ribs. It should be understood that panel 10 in commercial form will have louver ribs 14 provided on both sidewalls 12. Louver ribs 14 may be arranged in parallel rows extending from sidewall 12 as illustrated in FIGS. 1 and 2, or they may vertically from sidewall 12.

[0011] An alternative embodiment is illustrated in FIG. 2 in which louver ribs 14 are curved, undulating or elliptical in shape. Other embodiments contemplated by the present invention include any and all irregular (non-straight) shaped louver ribs.

[0012] As shown in FIGS. 1 an...

Abstract

Irregular shaped louvers, such as chevron or curved shape louvers, on the sides of a roof ridge vent panel provide increased surface area and great Net Free Area values within a given space.

Description

FIELD OF THE INVENTION [0001] The present invention relates to roofing products. More specifically, the invention relates to louver openings on roof ridge vents. BACKGROUND [0002] It is useful, and in many locales a building code requirement, that the attic area of a building be provided with a means to permit air exchange. Such ventilation prevents undue heat buildup, which can render the living quarters of the building uncomfortable and impose unreasonable energy requirements for cooling. Proper ventilation of the attic area also tends to preserve the structural integrity of the roof and roof coverings. One method of venting the roof structure consists of applying a venting media over a slot present along the ridge of a roof. These types of vents are known as ridge vents. Ridge vents are generally secured to a roof surface via a nail gun. [0003] Louvers are usually provided on the ridge vents to facilitate the passage of air through the ridge vent. Louver openings on ridge vent pr...
