The VENT Apron Vent RV10P Half is a Polypropylene Vent which enables warm air to escape from the lower roof void or through the barge detail of a mono-pitch skillion roof. The RV10P Half has an adhesive and flexible aluminium flashing which is designed to form to roofing profiles and prevent water ingress on any pitch roof.
The RV10P Half forms part of a passive ventilation system that works year round with no moving parts or energy consumption.
The RV10P Half is designed to be compatible roof cladding profiles with a trough depth of <38mm.
Roof Ventilation Products have been appraised for use as non-structural roof battens and vents for use with pitched and skillion roof construction on buildings within the following scope:
The VENT Ventilated Apron Vent (RV10P Half) is recommended on all abutment details and on all mono pitched skillion roof types irrespective of the degree of the pitch of in order to draw the airflow through these tight roof designs. The RV10P Half is essential to allow the natural convection action of rising warm air maintains a continuous airflow along the underside of the roof.
The vent is placed over the roof cladding and under the flashing detail. It is fixed by means of adhesive flashing tape that secures the RV10P Half into position. The steel flashing is then placed over the top and fixed through the vent into the top timber batten or steel purlin as per usual practice. The adhesive flashing tape has a 60% flexibility and has been tested on roofing steel roofing profiles with a rib height of up to 46mm, which enables suitability to most steel roofing profiles. The adhesive tape creates a water type seal which prevents driving rain or water from entering the roof.
The product can be utilised on both residential and commercial projects.
The VENT Ventilated Apron Vent (RV10P Half) is designed for use on profiled steel roofs and can be used in all climates and weather conditions. The VENT Ventilated Apron Vent must be used in conjunction with other VENT products to ensure a complete ventilation system.
Applying the VENT Ventilated Apron Vent without unimpeded eaves ventilation can result in additional moisture being drawn into the roof cavity as a result of the negative pressure created by the prevailing wind.
