ABSTRACT:
BACKGROUND OF INVENTION
The device relates to a roof vent that is adapted to prevent damaging amounts of snow from accumulating in the interior of a home or other facility.
SUMMARY OF THE INVENTION
Roof vents are commonly used in the home construction industry to vent the interior portions of a home or some other type of building while preventing environmental elements such as rain and snow from gaining access into the interior. However, in some climates, the roof vent is exposed to a combination of snow and wind. It has been found that this combination will actually cause snow to blow up into and through the vent and accumulate inside the vented area due to the design of the vent. When the snow then melts in the home, expensive water damage occurs. Thus, there is a need for a roof venting system that is economical to manufacture and which will help reduce damaging amounts of wind blown snow from gaining access to the interior space of a building.
It has been discovered that such a roof vent may be constructed by disposing within a roof vent a barrier layer of water resistant, porous fibrous material. This layer permits air to pass easily through it but prevents large amounts of snow from passing through. Thus, the barrier layer will only allow a small accumulation of snow in the portion of the vent directly above the barrier while preventing damaging amounts of snow from accumulating in the interior where water damage may result.
