You can paint on some rubbery gunk to create artwork on the surface to be sandblasted to repel the sand and leave clear areas.</div><div><br></div><div>The translucent panel would then be inserted in the opening first, followed by as many layers of insulating glass as you want. You could make the openings better insulated than your opaque walls if you wanted to. No reason translucent panel has to be just white though. Since the air barrier will be the IGUs , pieces of coloured glass could be included when making the insert panel.</div><div><br></div><div><br></div><div>On Fri, 30 Jun 2017 12:36:57 -0400, Sacie Lambertson <sacie.lambertson@gmail.com> wrote:<br></div><br><blockquote style="margin: 0 0 0.80ex; border-left: #0000FF 2px solid; padding-left: 1ex"><div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">All, since there remains a bit of life on this forum, I thought I would ask if any of you have a suggestion for a material that has some R-value to it but is at the same time translucent.

The windows will never be opened but I do want light through them during the day. They will have glass shelves in front of them too so shades etc are not in the cards.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Suggestions welcome.
