FEATURES AND BENEFITS
Hat Top Airflow Ridgevent
Installed at the apex portion of the roof, Located precisely where they do the most good NO puncturing or cutting sheets in between roof slope
For installation puncturing or cutting sheets in between the roof slope is required
Simple to install no leakage issues
Failure of workmanship can result in leakage
No rotating parts has Long durable life and effective performance
Self-weight that require wind to make them effective. These moving parts inevitably wear out
Maintains a clean, attractive roofline for all types of industrial building
Projected conical dome in between roofline
Easy to install at all Roof profile design and on an old existing profile
Turbo base need matching roof profile design
Best for planning solar panel installation in future, Due to its ideal peak installation position
Puncture the roof slope at regular intervals create a hurdle in the future for solar panel installation planning and cause of leakage
Maintenance-free with long performance life cycle
Due to rotating parts and FRP or polycarbonate base require maintenances and monitoring
Maintains a clean, attractive roofline – hidden underneath louvers ridge cap
Patch-wise dome section in the middle of roof slope
Low volume less transportation cost, additional saving No ridge flashing required
High volume more transportation cost
Can perform in high wind area
May be vulnerable to topple over in high windy area
Fast and easy installation with throughout ridge length ventilation
Installation takes more time and costly with patch wise ventilation
Best For high rise industrial building
Maintenance or performance failure can be a big issue
“Ventilation should never be an afterthought in constructing a factory building, Your building needs to breathe”
» Ensure roof sheeting is straight with no steps between roof sheets before installation of Airflow ridgevent of louver plate, especially regarding hip cut sheets. Maintain a minimum 100mm to maximum 150mm gap between sheet ends.
» Roof sheets are NOT to be turned up
» Slide louver plate over the end of the sheet until in correct position
» Starting from the left end pull down firmly on the louver plate install with a metal self-tapping self-drilling screw through the top row of louver plate to hold in place
» On the right end pull down firmly on the louver plate, install with metal self-tapping screw drilling through the top row of louver plate to secure in place
» Install STSD screws in the bottom row of louver plate directly below top screws to ensure installation (each piece must have evenly spaced screws) as per manufacturer’s recommendations, seal right side join with silicon sealant for a complete seal
» Slide next airflow Ridgevent louver plate on an angle overlapping the previous louver plate until locked into place, pull down firmly and install 19mm/ 25mm screw/ rivet and continue as per previous steps (each piece must have eight screws) where joins do not meet on a sheet rib secure with two screws
» Continue to install each Airflow Ridgvent louver plate on both sides of top ridge and hips where required
» Install ridge cap over fitted Airflow Ridgevent louver plate and secure to either batten or every second roof sheet rib.
IMPORTANT INSTALLATION NOTES
» Do not turn up the sheets. For roofs with a pitch of under 4 degrees, please contact the manufacturer for installation instructions.
» When laying the roof sheets, please ensure the sheets are laid straight.
» Silicon all joins, in particular ensuring that there is no gap
» Always follow the manufacturer screw pattern guidelines.
» The throat gap between the Air Flow Ridge vent louvers is recommended to be minimum 75mm minimum.
» For retro-fit installations, previous screw holes are to be sealed for waterproofing.
