What is driving rain?
Source:Â www.pfb-rosenheim.de
Driving rain is a combination of rain and wind.
This article explains why driving rain can be problematic, the test procedure for driving rain tightness - especially with reference to DIN EN 1027 - and the products you can use to ensure driving rain-proof façade fixings.
Watertightness against driving rain using the example of the ResiTHERM® 16 distance mounting system
Problem:
The wind creates pressure that pushes the water against the fixing point.Â
If this is not sealed, there is a risk of water penetrating the façade due to driving rain. This can result in mould growth or, in the worst case, destruction of the plaster, frost damage and damage to the building fabric, as explained in our article about thermal bridges.
Therefore, the usage of driving rain tight (synonym for rainproof) products is of great importance - especially for fastening products that are to be installed on the façade.
Testing for driving rain tightness
During the test, a test frame containing the plastered insulation board with the installed products is installed in the test chamber. Then the sprinkling is started in the resulting testing room and the pressure is increased stepwise, following DIN EN 1027. The highest pressure level is an overpressure of 600 Pa, which corresponds to wind force 11 (Beaufort scale) or, in other words, a hurricane-like storm.
After the test period of 55 minutes, the test frame is removed, the products will be screwed out and the institute assesses whether or not water has penetrated the insulation.
Test procedure with reference to DIN EN 1027
This European standard regulates the procedure and requirements for the test.
For example, the test is carried out under the following conditions:
- A water spray system wets the entire surface of the test element
- In a special measuring chamber whre the amount of water and the pressure is conrolled and regulated
DIN EN 1027 provides for two different installation methods:
Method A
Installation without structural protection: The installed products are thus completely exposed to the weather.
Method BÂ
Installation with structural protection: The installed products are protected from the weather by porches, balconies etc.
Test procedures for CELO's products:
Products tested according to procedure A. During the test, the test pressure is increased stepwise with defined preassure and time steps acc. EN 1027.
The products were tested up to 600 Pascal (Pa) - see above test procedure with reference to DIN EN 1027.
The test is passed if no moisture enters the insulation material.
TEST RESULT: Watertight agains driving rain using EN 1027 (method 1A). For further specifications, e.g. the plaster grain size, please refer to the brief report:
