Hi everyone. Some advice needed if possible. I intend to replace a few misted units into hardwood frames. In the past I have used butyl putty but intend to use security glazing tape to stick the inside face of the units to the inside of the rebates. One thing I am not sure about is do I will still be left with a 5mm gap all around the edge of the unit. Do I use any tape on this part of the unit. Hope this is easy enough to understand. I mean the edge of the units that has the brown seal all around it and sits on packers at the bottom edge of the unit. Any advice appreciated.
