Ventilation

Willis Westcott

This table is designed to provide an easy, at-a-glance guide to ventilation requirements in respect of the most common roof types, and to the Klober products which can satisfy those requirements. In many cases a product exists, and product selection will depend on several factors - such as whether it is new build, re-roofing or refurbishment work, and whether ventilation is preferred through the soffit or over the fascia. The ventilation requirements are the minimum levels set out in BS 5250. There may well be instances where additional ventilation is thought advisable and, of course, unusual roof types will demand special consideration.
