A weather louvre, such as Universal Louvre, is designed to let air through whilst restricting the entry of rain.
It is designed to perform both these functions simultaneously and its suitability for a particular application is determined by how effectively it achieves these functions in combination.
It is important for system designers and specifiers of such louvres to understand and clearly express the performance requirement at the design or procurement stage and select the correct type of louvre in order to achieve optimum performance and so as to avoid the risk of the product not being fit for purpose.
The rain defence characteristics of the Universal Louvre range are demonstrated under HEVAC 4th Edition test conditions on the Colt test rig.
