Wind Driven Rain Testing of TapcoSlate Classic to EN 15601 at 14 Degrees

This report describes driving rain tests carried out by BRE to determine the performance of Tapco Classic Slates to wind driven rain. The testing was carried out to the requirements of prEN15601. The main conclusions from these tests are: The Tapco Classic Slates when tested at a roof pitch of 14 degrees perform better than the reference products they are compared with. At a roof pitch of 14 degrees the Tapco Classic Slates are expected to perform satisfactory under wind driven rain. As the roof pitch increases the weathertightness performance of tiles and slates tends to improve. Therefore, it is expected that the Tapco Classic Slates will also perform satisfactorily at pitches steeper than 14 degrees.
