Use of VentGLAND recommended
In order to prevent condensation problems, we recommend using the WISKA VentGLAND. The higher the IP value of a device, the more condensation problems arise, since due to pressure differences (e.g. due to daytime/nighttime temperature differences) inside and outside the device, humid air will penetrate into the device and condense. Using a VentGLAND which compensates these pressure differences resolves this problem.
The VentGLAND can be supplied in brass or plastic and in a range of versions. A VentPlug with the same functionality also forms part of the delivery programme.
