Why TRI-BUILT Airflo Ridge Vent is the top performer! 1. Goal: To maximize the lift principle (Bernoulli Law) of an airfoil. (designed efficiently like an airplane wing) Our ridge vent was not just a copy of the many ridge vents on the market. It was researched and developed in conjunction with the roofers, specifiers and engineers to be the most effective vent. Note: The drawing below, which shows that our vent is designed in the same fashion as an airplane wing. Competitors such as Air Vent, GAF, Elk, Solar, Benjamin Obdyke and another dozen other copies, all use a similar design shown as a "V" external baffle. The differences become obvious when you compare to an airplane wing. TRI-BUILT has even gone so far as to sink the shingle down into the body to maintain the Airfoil Technology when you add shingles. Applying shingles to the competitors ridge vent adds to the inefficiency. 2. Goal : No clogging filters or debris catching design This was the by far the highest and most important issue to the roofers who we consulted. Filters are said to prevent snow, rain and insects from entering the attic space (see attached brochure of one of the competitors). Many state that the filter they have will stop clogging at 10%. At least they do reference that they clog. Why do they stop at 10%? If snow and rain are getting into the filter then why not dust? Filters in our furnaces have a much higher controlled wind source but they clog and have to be changed monthly. Reason tells us that over time, the efficiency of the filter vent slowly reduces and reduces. This lack of ventilation will cause attic space to heat up and shingle life to be shortened. The Airflo Ridge Vent overcomes the infiltration of snow, rain and insects with its weather control design. It was designed to ensure the precipitation enters where we want it, and once inside, it is blocked from the wind. Moisture runs out through our designed weeping holes. To add to this problem is the debris catching "V" design, which collects leaves and twigs. It is accessible unlike the internal filter but do we really want the homeowner maintaining this? Do we even tell the customer that this is required to maintain air flow?
