GALVANIC REACTION - HEAT TRANSFER PLATES

Kent D.

Will using standard steel wood screws to fasten aluminum heat transfer plates to subflooring create a galvanic reaction? My impression is that, in the absence of water, no reaction will occur. The joist bays should be dry and therefore no reaction, right?

Otherwise, what type of screw should be used? - Stainless steel? - Pricey!

Here in Humidity Heaven.......

if there would be any issues, they would certainly show here. I have some 5 year old extruded plate systems with no evidence of corrosion and I've used screws, nails and staples. You're correct, unless there is water present, it's a non-issue.
