How does a ventilator's design make a difference in its long term effectiveness?
Last Updated 9 years ago

We incorporate the "Lomanco Balance", which simply means you get the maximum ventilating capacity and the best weather protection available. Let’s examine how this is achieved:

  1. Ridge Vents: For a ridge vent to work it must have an exterior baffle. Once the wind hits the baffle it will create a low-pressure area around the ridge vent and pull air from the attic. Lomanco’s Omni Ridge shingle over ridge incorporates an exterior baffle the full length of the ridge vent plus patented Omni baffles utilizes the winds when parallel to ridge vent.
  2. Turbine Vents: Any ventilator with moving parts must provide longevity. The Whirlybird® turbine ventilator is a prime example of a well designed/ engineered product. It’s dual ball bearing system and weight load distribution enables Lomanco to offer a Forever Guarantee transferable from homeowner to homeowner. Remember if a turbine is not turning it is not working!!
  3. Intake Vents: Lomanco’s under-eave vents incorporate an "eyebrow" designed opening to insure the ventilator can not be crushed down and the ventilator capacity closed off.
  4. Roof Vents: The Lomanco 750 is engineered with a tall collar or stack. A ventilator is a lot like a chimney. The higher the stack the better the draw. If you lower the stack – you get down drafts. Cubic Foot per Minute testing has proven the 750 superior to other 50 square inch vents on the market. In addition to its capacity to ventilate, the 750 will not leave those unsightly discoloration circles on your shingles
  5. Power Ventilators: The LomanCool 2000TH comes complete with a built in thermostat and humidistat. Most power vents on the market today are equipped with thermostats and only operate when temperatures in your attic reach approximately 100 degrees. Since attic ventilation is required year around, a humidistat must be installed to activate the unit based on excessive moisture being present in the attic area.
  6. Gable Ventilators: We use more metal (aluminum) when manufacturing our 900 series adjustable triangular gable vents. This allows us to have a wider pivoting blade for better weather protection. Even though we may have the same number of blades as a competitor, our frame length will be longer thus providing you more net free area of ventilation capacity.
  7. Foundation Vents: The aluminum construction of our most popular model, 179, provides a workable unit at all times. Aluminum will not rust. Some other foundation vents on the market use galvanized steel with raw edges. Once the rust forms the unit becomes stationary, and unfortunately it is usually rusted in the closed position, robbing your home of its protective air movement.
