Abstract
A roof venting system for removing warm and moist air from the interior of a building to the outside through a vent opening in the roof. The system includes a vent, cover member for placement over the vent opening and two foam members through which the indoor warm and moist air must pass when the air flows from the building interior to the outside. The foam members may be provided with a convoluted surface to facilitate close engagement to the roof profile, and a single piece foam may be used instead of the usual two. The foam and cover members may be flexible, reticulated polyurethane treated with one or more substances to enhance fire resistance and protect from heat/cold adverse weather.
Description
- 1. Field of the Invention
- The present invention relates to metal roof systems and shingle roof systems that are used in both commercial and residential buildings and, more particularly, to vent coverings which allow for airflow and prevent foreign contaminants such as insects, birds, small animals and excess water from entering a roofing system by forming a partial seal.
- 2. Description of the Prior Art
- The life span of any roof will be increased if adequate ventilation is provided along the top vent of the roof. Ventilation is needed to allow air to flow through and out of the roof interior and out of the vent which is located along the top of the roof where the two slopes of the roof nearly meet. Having adequate airflow that uses roof ventilation is a proven construction technique that is used in both new construction and remodeling existing structures. Ventilation of the roof has been historically accomplished through the use of fabricated metal enclosures and complex fabricated plastic parts. In the 1970's, flexible reticulated polyurethane was used to achieve acceptable airflow and to solve the invasion of foreign debris small animals. While this material solved numerous problems, it still had several troubling shortcomings such as shrinkage, early deterioration, insufficient strength, low ultraviolet resistance, low tear resistance, density and low fire retardancy.
- Beginning several years ago and in response to customer requests, research was directed to providing a better venting product than those then in use. Experimentation continued into the year 2000 and thereafter. Different materials were tested, but no acceptable version was identified until a few years ago when it was determined that reticulated polyurethane had the essential characteristics needed for a successful venting system. Later it was determined that this material when used would quickly begin to degrade because of poor ultraviolet resistance, poor hydrolytic stability, and the inability to meet building codes as a fire-retardant material used in construction.
- More recently, a new, flexible, reticulated, polyurethane material was produced and, when tested, verified that it would prevent excess water from being driven by wind back through the ventilation material and into the roof interior. It was designed to withstand ultraviolet radiation for prolonged periods, and it was also designed to comply with building material standards and made fire resistant. The material proved successful and demonstrated that it would provide superior airflow for a roof and prevent wind-driven rain from entering the building. Thus an improved vented closure strip has been and continues to be very desirable, and it is to that end that the present invention is directed.
- A primary objective of the present invention is to provide a roof venting system that has all of the advantages of prior art devices and more, and none of the disadvantages.
- Another objective of the present invention is to enhance the outward flow of air from the region beneath the roof and at the same time inhibit the inward passage of moisture and insects.
- Yet another objective of the present invention to provide a vent cover which engages a pair of laterally spaced open cell members so that air can freely flow outwardly therethrough while the entry of moisture and insects in a reverse direction is inhibited.
- Still another objective of the present invention to provide foam members having a multiplicity of interconnected open pores so that maximum airflow is achieved and at the same time an optimum restriction to moisture and insects in an reverse direction is realized even when the moisture is in the form of wind-driven rain.
- A further objective of the present invention is to provide a roof venting system that is readily conformable to the slope of the roof to which it is attached.
- Yet another objective of the present invention is to provide sections of predetermined length, yet enabling any section to be cut to a lesser length during installation, such as when the last section must be shortened to match an end of the roof.
- Yet another objective of the present invention is to provide a system having longevity through heat/cool cycles.
- Still another objective of the present invention is to provide a system having hydrolytic stability.
- A further objective of the present invention is to provide a system that will withstand oxidation.
- Still another objective of the present invention is to provide an inexpensive roof vent system which will be virtually maintenance-free.
- The invention in it broadest form is a roof venting system for covering a vent opening in the roof extending substantially for the length of the roof ridge permitting ventilation from the interior space under the roof to the exterior. The system includes a vent cover covering the vent opening extending over the opening for the length of the opening and overlapping the opening substantially evenly on each side. A pair of laterally-spaced, flexible, reticulated polyurethane foam members have first and second faces, the second faces engaging one side of the vent cover and the first faces engaging the roof profile.
