How to Order
Measure the overall length of the eaves to be ventilated and divide by 2.4m (product length) to determine the number of ventilators required.
- The corbel ventilator is designed to be fitted at the same time that the corbelled brickwork is completed
- The fixing clips have protruding tabs which are built into the perp. mortar joints on the top row of brickwork
- If the ventilator is not fitted at this time, the fixing clips cannot be used as intended and it will be necessary to drill and plug the brickwork or fit a timber batten on which to fix the ventilator
- Only available as a 10mm continuous opening version. If ventilation is required equivalent to a continuous 25mm opening then an alternative product must be used
- It will be necessary to fit this by drilling and plugging the brickwork or fitting a timber batten on which to fix the ventilator
- It is strongly recommended that a plywood felt support is fitted directly above the corbel ventilator in order to prevent sagging roofing felt from restricting airflow through the ventilator. This should project at least 15mm beyond the front of the ventilator
- Make sure that each ventilator is fixed securely to the top row of corbelling using all 8 of the fixing clips provided
