New IN-Vent

(From April 2007)

Cor-A-Vent's newest product is here. The IN-Vent™ is an on-the-rooftop intake vent that lets fresh air in when soffits are out™.

IN-Vent is ideal for roofing contractors who need to add intake ventilation, but can't access the soffits or overhangs. IN-Vent comes in four-foot pieces and provides 6.75 inches of Net Free Vent Area (NFVA) per lineal ft. When installed on both sides of a roof, it will provide 13.5 inches NFVA, a perfect match for Cor-A-Vent's V-300 or Fold-A-Vent (FAV-20) ridge vents. A carton of IN-Vent contains 64 lineal feet of vent (16 four-foot pieces) plus two End Cap sections and a bag of 2 1/2" roofing nails.

Anonymous said... My 1914 house does not have any soffits. There is no roof deck, and no ridge vent. The roof boards have spaces between them now(original roof was probably wood shingles) but that will change when the new roof deck goes on. There are very small gable vents. There is rockwool insulation directly between slanting living space ceilings and the roof.I plan to put on a new plywood roof deck and architectural asphalt shingles. How can I ventilate so it won't get too hot? May 26, 2010 5:06 PM Steve said... IN-Vent can be used in this situation, but before the new plywood deck is put down, you'll need to have vent chutes (also called insulation baffles) installed to create an airspace between the insulation and roof deck. We also recommend closing off the gable vents from the inside and installing a ridge vent at the peak for the best airflow possible.
