This vent is a 400 x 200mm. Beneficial all year, it keeps the roof cool in summer months, and prevents dampness/mould in contrast. A steel construction with steel mesh protects it from insects and rodents. The vent is designed for use with rotary roof vents for air intake. Please note, it does not include fixings – six 15mm x 8g button head screws are required (per vent).
Compliant with fire rating requirements up to BAL-40
