Why TRI-BUILT Airflo RidgeVent is the top performer!

1. Goal: To maximize the liftprinciple (Bernoulli Law) of anairfoil. (designed efficiently like an airplane wing) Our ridge vent was not just a copy of the many ridge vents onthe 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 designedin the same fashion as an airplane wing. Competitors such as AirVent, GAF, Elk, Solar, Benjamin Obdyke and another dozen othercopies, all use a similar design shown as a "V" external baffle.The differences become obvious when you compare to anairplane wing. TRI-BUILT has even gone so far as to sink theshingle down into the body to maintain the Airfoil Technologywhen you add shingles. Applying shingles to the competitorsridge vent adds to the inefficiency.

2. Goal : No clogging filters ordebris catching designThis was the by far the highest and most important issue to theroofers who we consulted. Filters are said to prevent snow, rainand insects from entering the attic space (see attached brochureof one of the competitors). Many state that the filter they havewill stop clogging at 10%. At least they do reference that theyclog. Why do they stop at 10%? If snow and rain are getting intothe filter then why not dust? Filters in our furnaces have a muchhigher controlled wind source but they clog and have to bechanged monthly. Reason tells us that over time, the efficiency ofthe filter vent slowly reduces and reduces. This lack of ventilationwill cause attic space to heat up and shingle life to be shortened.

The Airflo Ridge Vent overcomes the infiltration of snow, rain andinsects with its weather control design. It was designed to ensurethe precipitation enters where we want it, and once inside, it isblocked from the wind. Moisture runs out through our designedweeping holes.

To add to this problem is thedebris catching "V" design,which collects leaves andtwigs. It is accessible unlikethe internal filter but do wereally want the homeownermaintaining this? Do we eventell the customer that this isrequired to maintain air flow?

3. Goal: Insect protectionCodes and Standards in North America reference a gap of amaximum of 1/8" in the venting space for insect protection. Thisreference is important as it is specified to prevent harmful flyinginsects. This gap was researched at several U.S. Universities andgiven to manufacturers to ensure that insect problems would beeliminated. Many reputable companies like TRI-BUILT, Durafloand Lomanco follow these standards religiously. As theillustration shows below, many of the competitors use grills thatare double the Standard spacing. Some even offer models thatdo not offer a filter to prevent infiltration of insects thusproviding no protection at all.

TRI-BUILT meets the international standard ofinsect protection without filters.

4. Goal : Expansion and contraction controlPlastic roof vent flanges raise up to three quarters of an inchfrom the summer heat (18" approx. average length). Ridge ventsare at least four feet (48") in length yet no provisions are takenfor this expansion due to the weather. The illustration below is an example of how poorly a ridge vent can look when itexpands. Our focus group of roofers commented that they oftenare concerned over the high price charged for ridge ventingwhen it buckles in the heat. The buckling of the ridge can add tothe risk of insect and weather infiltration. It is supposed todisappear on the roof but often looks worse than otherventilation methods. They asked us “can you make a ridge ventthat will lie down straight?”

TRI-BUILT has made the vent with holes in the center which actas expansion and contraction points. This avoids unsightlybuckling at the edge of the vent keeping curb appeal whilemaintaining the weather and insectresistance.
