ERD is an extruded Single Bank Louvre System designed for applications requiring ventilation with a good degree of rain defence.
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):
