A ridge vent comprising a pair of opposing vent parts each fabricated from a plurality of stacked, interconnected layers of a corrugated plastic sheet material and a top panel extending between and connected to the opposing vent parts, with the entire assembled ridge vent being rolled into a spiral or coil, and secured in that configuration for later installation on a roof. The assembled ridge vent is rolled into the spiral configuration from an initially planar configuration by engaging a leading end of the ridge vent and rolling the ridge vent onto a drum or mandrel to form a tight, uniform spiral. The rolled vent can then be labeled and banded or packaged. The fabrication process from bulk rolls of sheet material to packaged roof vents can be substantially continuous and automated. Roof vents of various lengths or widths can be manufactured with only minor adjustments or substitutions in the fabrication equipment. The ridge vent is installed by placing the roll on the peak of the roof with the free end of the spiral extending over the top of the spiral and oriented away from the direction of installation. The blank is unrolled to expose a portion of the ridge vent, which is fastened to the roof. This process is repeated until the desired length is installed. Foam end caps and air deflectors optionally may be installed.
An improved roof ridge ventilation system utilizing a mat of randomly-aligned natural fibers which formed into a web by air-laying on a polyester mesh and bonded with a heat-cured latex bonding agent. The natural fiber mat provides improved airflow while excluding water, dust and pests such as insects and rodents and is more economical that competing materials. The mat is conveniently manufactured in rolls for ease of transport and installation.
A baffle adapted to be rolled with a ridge vent is comprised of an L-shaped configuration having first and second legs. The first leg is adapted to extend under the ridge vent. The second leg is adapted to be oriented at an angle relative to the first leg and some distance from the ridge vent when the baffle and the ridge vent are installed. The first leg is also adapted to be rolled. The second leg is adapted to collapse when the first leg is rolled. The invention is also directed towards a ridge vent in combination with the baffle and a method for forming the baffle.
A precipitation resistant ventilator for a structure enclosing an interior space. The ventilator encloses a space that is in communication with the structure interior space. A thin sheet of air permeable water resistant material is disposed within the ventilator interior. The thin sheet of air permeable water resistant material forms a barrier that excludes the entry of precipitation and other foreign matter into the roof structure while still allowing air exchange.
A ridge cap vent for enabling air exchange between an interior and an exterior portion of a roof and a method of installing the ridge cap vent are provided. The ridge cap vent is conformed to be disposed between an upper ridge cap member and a lower member. The ridge cap vent may be formed from a corrugated plastic material and includes a multiplicity of air passages extending generally transversely to a longitudinal axis of the ridge cap vent.
