The louvre system achieves minimum performance coefficients (Cv) of 0.30 (inlet) and 0.29 (extract). These have been established as the result of full-scale wind tunnel tests.

The louvre system achieves the following weathering classification when tested against the EN 13030: 2001 standard (method of test for water rejection performance of louvres subjected to simulated rainfall):

  • Class A2 - up to 0m/s suction velocity
  • Class B2 - up to 1.5m/s suction velocity
  • Class C2 - up to 2.0m/s suction velocity
  • Class D2 - up to 3.5m/s suction velocity
