If the glass is an IG unit (double pane), then you can add SDLs to the exterior of the IGU (interior and exterior the home) with or without grills between the lites. It's done both ways and both ways are relatively common.

Otherwise to repeat my answer from the other thread...and doesn't matter if single pane or dual pane, the reply is the same.

Make sure that the glass is meticulously clean and for best results use an adhesion promoter on the glass and SDL muntin bar as well before applying the tape.

Attach the VHB tape to the muntin bar, leaving the paper on the other side.

Pull about an inch or so of paper off the tape to the side, but don't tear it.

Carefully lay the muntin bar on the glass allowing the exposed tape to adhere to the glass.

Then slowly pull (to the side) the remaining paper from the tape as you press the exposed tape to the glass.

You won't have full adhesion immediately, and you can remove the tape from either surface at this point, but better if you don't have to.

No caulk or other materials/adhesives are needed.

VHB is amazing stuff. I have been involved with glass ceilings that were attached using VHB tape to hold the brackets that were used to attach the HEAVY glass panels in place.

Thank you so much for all the installation tips! This is all so helpful.
