Imerys Beauvoise Tile Vent – Kit
Roof Ventilation should comply with building regulations and the control of condensation on buildings.
The level of ventilation depends firstly on the roof design. Cold or warm roof construction,the type of membrane being used, vapour permeable/breathable or impermeable underlays. Also, roof pitches above or below 35° or roof spans that exceed 10 metres.
As a guide for most situations, ventilation should be introduced at eaves or low level. This should be 10,000 or 25,000 mm2/m and 5,000mm2/m at ridge or high level. There should be spacing of 1 or 2 metres.
