Used to provide ventilation where flat roofs abut masonry.

The RAV-FL promotes air entry where a flat roof abuts a vertical masonry wall. It is supplied with pre-drilled fixing holes and an integral insect-resistant grille. Each unit is 1.2 metres in length and the heavy-duty profile incorporates an integral pivothold hinge. This hinge permits easy and direct fixing, as the profile may be secured to the vertical board upstand when opened like a book. The profile is then closed and fixing completed by securing the top of the profile to the masonry wall. An air ventilation path which complies with the current regulations is established at the flat roof intersection. The product is compatible for use with our horizontal intersection cavitrays which may be established at a higher level to permit the flashing to be dressed down to cover the external shell of the RAV-FL profile.


  • RAV-FL = 1.2 metres x 200mm o/a x 50mm o/a x 3mm thickness.
  • Integral ventilation grille promotes equivalent of a 25mm continuous gap.
  • Grade A1 compound PVCU, grey.

Questions & Answers


What is the minimum level the vent need to be fitted at. I have a upstand that is 130mm to the underside of the door threshold.


Please call in and speak with a team member as there may be alternatives to discuss 


I don’t understand where the air flows to if lead flashing covers the whole vent. Where is the moist air going?

Hi do you supply a flashing kit for this roof ventilation kit?


Nothing specific is provided with it, you can flash over the top of it with Lead or Lead alternative, whichever flashing you prefer.


Does this product require a flashing over the top? What gap is required between the upstanding and the wall. I have a 50 mm wall plate.


You do need to Flash over the top to create a water tight seal, you would ideally want at least a 25mm air gap for ventilation.

Too short, too wide and bulky, too expensive, badly designed. Could have been done so much better. Waste of money better build your own vent from plywood and resin
