BSRIA has the only independent testing facility in Europe, and is one of two in the world, to test weather louvres against EN13030.
The test at BSRIA is based on a method that realistically simulates the actual operating conditions that a louvre will undergo when installed.
This is achieved using rain, ventilation and simulated wind speed.
Special applications and standard louvre testing
The louvre test provides a verifiable evidence of a louvre's ability to keep out water when installed. The test can establish water rejection performance over a wide range of conditions and it is used for:
