What is Sympatex?
Waterproof membrane which covers general demands in everyday life and particularly outdoor working. The waterproofness of the membrane is measured on the basis of the water column under the pressure of which the material starts to allow water through it. According to EN 343 a membrane is waterproof if it can resist a pressure of 1,300 mm. Pursuant to ISO 811 the Sympatex membrane far exceeds these values and is extremely waterproof with a water column of over 45,000 mm.
