raster overlay using Raster Calculator

Hello! I am trying to perform a simple raster overlay in Raster Calculator to get a final constraints layer. All of the layers  have been reclassified (0 - not suitable, 1 - suitable). I can multiply the layers with both 0 and1 values without problems but I also have some layers which only consist of 0 and NoData values (buffers around some objects that need to be excluded). Now when multiplying a layer with both 0 and 1 values with the layer that has only 0 values, the output will have only 0 values as well (basically getting the same reclassified input layer with only 0 values as the output).  NoData multiplied with 1 gives NoData? How could I solve this problem?
