About the Sub Floor Vents, Anti-Spark (BAL-40 Mesh)
VUETRADE Sub Floor Vents, Anti Spark are brick vents built in as the bricks or blocks are laid, fitted with an anti-spark 316 stainless mesh insert (0.9mm wire, 1.64mm aperture) that VUETRADE rates up to and including BAL-40 to AS 3959. For bushfire-prone sites up to and including BAL-40. The mesh cuts the airflow, so size the number of vents on the anti-spark figures. Galvanised in five sizes, and 230 x 76mm in 316 stainless. Cartons of 20.
