Acrylic Box vs Glass Box Frame
Acrylic box or glass-fronted box frame? How the two compare on clarity, weight, safety, UV protection and cost, and which suits which objects.
There are two good ways to put a three-dimensional object behind a clear case: a frameless acrylic box, or a traditional box frame with a glazed front. Both protect the piece properly. The right choice comes down to how you want the object seen, how heavy the finished case can be, and the look you are after.
We build both in the same workshop, so this comparison has no side to take. Here is how they differ.
What an acrylic box frame is
An acrylic box is built from panels cut from larger sheets, their edges diamond polished for a clean join, then bonded with specialist acrylic adhesive and UV-cured for strength. Butt-joined edges give a sharp 90 degree corner; alternatively a single sheet can be heat-bent into a curved profile that forms two or three faces in one piece. The result is a crystal clear case with no frame around it at all, usually mounted on a hand-finished subframe made for the object it supports. Because every face is transparent, the piece can be viewed from more than one side, and the whole display reads as light and minimal on the wall, a table or a pedestal.
What a glass-fronted box frame is
A glass-fronted display starts with a deep timber box frame, built to whatever depth the object needs and finished in any colour or material. The object sits against a mounted backing inside, and the front is glazed in standard, anti-reflective or museum-grade glass. It is the classic presentation: a defined frame edge, a mount, and the object staged within it. If you are weighing this style against shallower cases, our comparison of box frames and shadow boxes covers the terminology.
Clarity, weight and safety
Good acrylic is optically as clear as glass, and it is dramatically lighter, which is why our largest frames are glazed in acrylic regardless of style: the weight saving is what makes a very large case hangable at all. Acrylic also does not shatter, which matters in family homes, schools and public spaces. Glass resists surface scratches better in day-to-day handling; acrylic marks more easily but, unlike glass, it can be restored. Small marks are polished out in the workshop, and we use a flame polisher, an ultra clean, very high temperature flame that briefly melts the surface, to bring edges and faces back to full clarity.
Conservation and UV protection
Both routes protect properly. Glass-fronted box frames take museum-grade UV-filtering glazing, and acrylic boxes are available in museum-grade UV-filtering acrylic, which is why galleries preserving valuable works use them routinely. In both cases the fixing of the object itself is non-damaging and fully reversible: nothing is glued into place, and for common objects like stretched canvases, books and small metal items we have developed dedicated mounting techniques.
Which suits your object
Choose an acrylic box when the object deserves to be seen from more than one side, when a full frame would be visually restrictive, or when a strong sense of light and minimalism is the goal. Sculptures, ceramics, memorabilia and floating canvases all suit it.
Choose a glass-fronted box frame when the piece wants a defined frame around it: shirts, medals, textiles and anything where a mount, a frame profile and a finish are part of the presentation.
You can browse finished pieces in our acrylic box examples collection to see how the frameless look lands in practice.
Cost and sizes
Acrylic box frames start from around £250, with the final price depending on the size of the piece, the thickness of acrylic required and the finishing of the support structure. Bespoke glass-fronted box frames cost around £350. At the top end of the scale, our oversized framing team builds bespoke acrylic enclosures up to 4.5 metres. Our acrylic box frames page covers the construction in full detail, and every case is built in our workshop as it has been since 1974, with a 5 year guarantee.
Frequently Asked Questions

Yes. Acrylic boxes are available in museum-grade UV-filtering acrylic, and glass-fronted box frames take museum-grade UV glazing. Galleries preserving valuable works routinely use UV-filtering acrylic cases.
-
Bespoke acrylic enclosures can be built up to 4.5 metres for the largest pieces, handled by the oversized framing team. Weight is rarely the limit because acrylic is dramatically lighter than glass.
