Attic Ventilation is an integral part of any thermal or radiant attic insulation system. Don’t be mislead; heat gain and moisture build up in an attic degrades attic insulation performance and proper attic ventilation is essential to attic insulation performance. Shingle over ridge vents, such as Superior’s Ridge Master Plus put attic heat to work for you.
When an attic heats up the heat naturally begins to rise up and out the ridge vent pulling fresh outside replacement air in through the soffit vents. No power, no noise, no moving parts, no operational cost. Solar power vents, electric power vents, turbine vents and even gable vents many times are part of the solution, yet in most cases they alone do not provide for balance ventilation. Spot ventilation is better than no ventilation however Superior ventilation is balanced.
Superior balanced ventilation is best achieved with a Ridge Vent exhaust system and soffit/eave vents for replacement air supply. With soffit/eve vents properly, sized, positioned and installed in overhangs Superior’s signature “black” vent chutes are then installed with insulation blocks to protect the replacement air flow from obstruction by the blown insulation, therefore maintaining specified Net Free Air Space requirements.
