Technical Information

  • Primary roof eaves ventilation
  • Ventilation must be provided for the full length of the eaves and along both sides of the building to create a cross flow ventilation action
  • Provides ventilation equivalent to a continuous 10mm opening (10,000mm²)

How to order

  • Determine if the project requires an integral eaves comb filler
  • Measure the overall length of the eaves to be ventilated and divide by 900mm (the length of the system), to determine the number of 3014 or 3014C ventilators required

Installation Advice

  • Over fascia ventilators fit onto the upper edge of the fascia board
  • It is important to note the height of the over fascia ventilator being used and make allowance for this when fitting the fascia board
  • If the height of the ventilator is not taken into account and the fascia board lowered accordingly, the tiles may be caused to 'kick up' at the eaves
  • Make sure that each ventilator is fixed securely into the top fascia board using screws or nails through each fixing hole provided
  • Roofing felt should be cut back flush with the edge of the fascia board and not dressed into the gutter
  • Ventilation must be provided for the fill length of the eaves and along both sides of the building to create a cross flow ventilation action
