25mm Over Fascia Vent

25mm Over Fascia Vent – Continuous Eaves Ventilation

Strong, discreet and easy to fit!
The 25mm over fascia vent provides continuous eaves ventilation, helping your roof to “breathe” by increasing airflow and reducing moisture build-up in the roof space. Its slim, interlocking design fits neatly to the top edge of the fascia board, giving long-lasting protection without spoiling the roofline appearance.

Manufactured from tough polypropylene, each vent strip includes stop beads for accurate positioning and pre-drilled nail holes for quick, secure fixing.

Features & Benefits:

• Provides continuous 25mm ventilation (10mm option also available)

• Lightweight but strong – made from durable polypropylene

• Discreet low-profile design for a neat finish

• Integral 4mm grill – keeps out birds and large insects

• Quick installation – interlocking strips with pre-formed fixing holes

• Suitable for new builds or retro-fit to existing roofs

Why Roof Ventilation Matters:
Poor ventilation in roof spaces leads to condensation and moisture, which can damage timbers and insulation. Building Regulations require continuous eaves ventilation to prevent damp and prolong the life of your roof.

Ventilation Capacity:

• 25mm vent – recommended for warm roofs, flat roofs, and roof pitches under 14°, equivalent to a continuous 25mm opening.

• 10mm vent – recommended for conventional cold roof designs, equivalent to a continuous 10mm opening.
