Double-Glazing Large Artworks

[PizzaFraming]

I have a regular who consistently brings in a large amount of works on canvas that have art on both sides. Because of this, I usually frame the works with acrylic on both sides, using 1/4" Arlo spacers with fillet tape to hold in the back piece. However, with works on the large end of the spectrum (over 24x36), I've found it doesn't really hold up over time. What are everyone's preferred fitting techniques for double-sided acrylic glazing?

We used 3/16 x 3/16 wood stock painted black and glued it to the rabbet. We sometimes caulked the piece in with clear latex caulk, but I liked the wood better.

Hi, and welcome to the G.

Do these canvases have any unpainted margins?
Canvases are normally stretched, and there are ways to stretch canvases with painting on both sides.
There is a technique called a Trampoline Mount that attaches the canvas around the perimeter to a stretcher that is then installed into a double frame (front/back) and I'm relatively certain glazing could be included.

Heck of a first question/introduction.

Thanks to your post, and the Grumble archive, I just learned about this.

... 1/4 to less than 1/2 inch side margin. The top and bottom margins are obviously smaller.

For a textile with narrow margins, Trampoline Mounting allows you to show all or part of the edges, and you can vary the tension of the Trampoline laces to straighten & square up the sides.

Also, you can make a presentation using recto/verso mats to show the entire back of the textile, which is a unique benefit of this mounting technique.

Here are a couple of photos...For more details & illustrated instructions, check the October, 2011 article, "Trampoline Mounting a Mola"...

When I do double-glazed pieces, I use 1/4" hollow Econospace spacers to hold the package into the frame, but I do not depend on the spacer's adhesive to hold everything. I squeeze 1/2"x20 brads through the spacers into the inner wall of the frame, using a fitting tool. It is easiest if you pre-start the brads into the spacers so that their points are just protruding through the spacer's adhesive side, then use the adhesive to hold the spacer in place as you squeeze the brads in until they are flush with the sight edge of the spacer.
