VENTILATED RIDGES LOW PROFILE - LP SERIES
These ventilated ridges provide low profile, low cost outlet ventilation with a level of weather protection adequate for most situations.
They are available in ZINCALUME® , COLORBOND® ‚ or Galvanised steel in lengths from 2.4 metres to 6.0 metres. They may be lap jointed (allow 100mm lap) into continuous vents, or supplied as stop ended units with matching ridge capping between the units. Fixing is by either pop rivets or drive screws through the side aprons and into the roof sheeting. The clear opening between the ends of the roof sheets to correspond with the stated "throat" size. |

Where it is not possible to achieve the required amount of ventilation through the ridge of the roof, or in the case of skillion roofs, the units may be "slope mounted" down the slope of the roof; in this case, the aprons are manufactured to suit the particular roofing profile. Matching ridge capping is also available.

In very exposed situations we recommend using either our T.E. Series ventilating ridges, or the fitting of our standard external "Anti Mist" baffles which deflect the wind over the top of the ventilating ridge and prevent any misting during severe rain storms.
All the above models may be "slope mounted" on skillion roofs, or in situations where it is desirable to distribute the outlet ventilation over the entire roof area.
Also available with 225 & 300 throat (airway as for LP 150)
