KELLER minimal windows®4+ Driving rain tightness Class E1050 according to EN 12208 Design sliding system permanently driving-rain-tight KELLER minimal windows®4+ design sliding systems achieve an outstanding driving rain tightness according to the EN 12208 standard with over 1,050 Pascal. 1,050 Pascal correspond to the high wind pressure of 105 kg/m² element area with simultaneous spray irrigation. KELLER AG has an in-house, certified test centre on which the corresponding performance tests can be carried out according to international standards and under the supervision of a recognised test institute. Sophisticated sliding door construction with maximum performance Tests on the test stand show up all the strengths of every construction, but they also ruthlessly expose its weaknesses. The KELLER minimal windows®4+ design sliding windows and doors feature structurally complex sealing technology. The use of high-quality seals guaranties top-class wind, air and driving rain tightness while at the same time ensuring low-friction, easy movement of the sliding leaf. This was confirmed in impressive fashion in the performance tests that have just been carried out. Our own targets were well exceeded with absolutely top values, in particular for the driving rain tightness, and values were achieved that have no equal in large-sized sliding systems: Driving rain tightness (> 1,050 Pa) Class E1050 (wind velocities of 150 km/h), wind force 12+ (severe hurricane) in accordance with EN 12208In the same test the well-known maximum values for air permeability and resistance to wind load were confirmed in impressive fashion: Air permeabilityClass 4 according to EN 12207 Resistance to wind loadClass C5 according to EN 12210 wind speeds > 200 km/h, wind loads up to 2,000 Pa (200 kg/m²) Wind, air and driving rain tightness is rapidly gaining in significance in these times of climatic change (heavy rain, storm gusts). The facade of a building is exposed to constant stress through wind and rain. The higher a window is installed in a building, the greater its resistance must be to wind loads, driving rain and draughts.

In reaching the 1,050 Pascal limit and with certification to Class E1050, KELLER AG has set new standards in driving rain tightness for design sliding doors and windows. More information on KELLER minimal windows®4+ sliding windows and doors
