Eaves VentilationEaves Ventilation |
| Roof ventilation at the eaves is specified in Building Regulations Approved Document F2, being required to provide either a 10mm or 25mm continuous air gap. Eaves to eaves ventilation is the simplest option for a standard roof void, but in most cases high level ventilation is also required. Brett Martin Harcon recommend high level roof ventilation in all cases, as it utilises the natural thermal uplift in a roof void. |

| The Harcon range of eaves accessories allows roof ventilation over the fascia board or at the soffit. Harcon over fascia roof vents, include a very low profile vent, and provide 10mm or 25mm continuous air gap. All are strong enough to resist collapsing under the weight of a roofer’s boot during installation or subsequent maintenance. Supporting items include comb fillers, fascia trays and rafter trays, all designed to ensure a continuous air path into the roof void and to prevent insect entry. |
