Mono pitch roof ventilation.

A placed on top of the purlins. Through the design and installation of specific product combinations an unimpeded passive ventilation system is created for a skillion mono pitch roof any degree pitch the following product combinations are recommended. G2500n vent over fascia vent which allows calculated airflow into the roof cavity vb20 vent vented batten performs two functions. Firstly the vent over fascia vent is fitted to the top of the fascia to allow calculated airflow of 25 000mm per linear metre into the roof cavity.

3944123 divisions of the building product design group. Roof with a pitch of less than 15 and those where the ceiling follows the pitch of the roof roof spaces should have ventilation openings in two opposite sides to promote cross ventilation. This video shows the construction of a skillion mono pitch roof and the application of the correct combination of products to achieve required continuous air. These openings should have an area at least equal to continuous ventilation running the full length of the eaves and 25mm wide see diagram c.
