25mm Over Fascia Vent

Increases airflow and reduces moisture in roof space

Durable and discrete interlocking 25mm eaves vents provide continuous eaves ventilation to encourage airflow throughout the roof system. Allows the roof to 'breathe' and discourages birds and large insects.

Each lightweight polypropylene vent features stop beads that simplify the fitting to top edge of fascia board and integral nail holes for consistent and secure fixings.

Features & Benefits

• New-build and retro-fit to existing roofs
• Low profile design
• Extremely strong and lightweight
• 4mm integral grill
• Fixing location holes
• 25mm ventilation capacity (10mm capacity also available)
• Prevents birds and large insects accessing the roof

Why it's important to ventilate the roof

Inadequate ventilation in the roof space encourages moisture, which can damage roof timbers. All new-build properties must have continuous ventilation at eaves level to avoid damp and condensation within the roof void and to comply with Building Regulations.

Ventilation capacity

This 25mm capacity eaves vent is recommended for warm roofs, flat roofs and roof with pitch less than 14° and provides the equivalent of a continuous 25mm opening. The 10mm capacity vent provides the equivalent of a continuous 10mm opening and should be chosen for conventional cold roofs.
