It's one of the most common questions we get at Artmount & Framing Matters: "Does the glass actually matter?"
Short answer: yes, it really does. And not just for aesthetics. The glass you choose plays a significant role in how long your artwork stays looking the way it does today. Get it right, and your piece will look great for decades. Get it wrong, and you might be looking at fading, yellowing, or worse — and wondering why.
Here's a plain-English breakdown of your options.
Standard Glass: The Baseline
Standard float glass is the entry-level option — clear, clean, and perfectly adequate for many everyday framing jobs. It lets light through, protects the work from dust and handling, and does what glass is supposed to do. It's also the most affordable option.
The catch? Standard glass only blocks around 40-47% of UV rays, which isn't enough for anything you want to preserve long-term. Sunlight and artificial lighting both emit ultraviolet rays, and over time, those UV rays cause artwork to fade, discolour, and deteriorate.
Best for: Posters, reprints, decorative pieces, or anything where longevity and preservation aren't the primary concern.
UV Glass: Protection Without the Premium Price
UV-protective glass filters out a significant portion of ultraviolet radiation — typically around 70–99% depending on the grade. This makes a meaningful difference to how well your artwork holds up over time, particularly for photographs and original artworks where fading is a genuine risk.
It's important to understand what UV glass does and doesn't do — it slows the fading process, it doesn't stop it entirely. How much protection you actually get also depends on the quality of the inks or paints used in the piece itself, so results vary from artwork to artwork. UV glass also isn't a green light to hang your piece in direct sunlight — it reduces the risk, but direct sun exposure will still cause damage over time regardless of the glass you choose.
It looks similar to standard glass, performs noticeably better in terms of protection, and sits at a more accessible price point than the premium options. For most framing jobs, UV glass is the sweet spot — solid protection without going all in on museum-grade materials.
Best for: Family photos, original artworks, prints you care about, anything in a sun-exposed room.
Anti-Reflective Glass: When Glare Is the Problem
Standard glass reflects light. In a bright room or opposite a window, that means you're often looking at a reflection of the room rather than the artwork itself. Anti-reflective glass addresses this by using a special coating that dramatically reduces glare, giving you a much cleaner, clearer view of what's inside the frame.
The result is something close to looking at the artwork without any glass at all — which is particularly valuable for photography and detailed fine art prints where you want to see every element clearly. Some anti-reflective options also include UV protection, which is the version we'd generally recommend.
Best for: Fine art photography, detailed prints, spaces with lots of ambient light or windows.
Museum Glass: The Gold Standard
Museum glass combines anti-reflective coating with maximum UV protection — typically 99% UV filtration. It's what galleries and museums use to protect irreplaceable works, and for good reason: it offers the best optical clarity available combined with the highest level of UV protection on the market.
It is, as you'd expect, the most expensive glass option. But for pieces with significant monetary or sentimental value — original artworks, heirlooms, historic documents, anything truly irreplaceable — it's worth every cent.
Best for: Original artworks, heirlooms, historic documents, anything irreplaceable or of significant value.
Conservation Glass: Archival-Grade Protection
Conservation glass goes a step further than standard UV glass, using archival-quality materials specifically designed to protect valuable works over the long term. It's often used alongside conservation matting and backing boards as part of a full archival framing approach — which is something we specialise in at AMFM.
Dixie brought conservation framing expertise back from London in the 1980s, and it's been a cornerstone of what we do ever since. If you're framing something precious, this is the conversation to have with us.
Best for: Valuable original artworks, historical documents, cultural taonga, family heirlooms.
So Which One Do You Actually Need?
Here's a simple way to think about it:
• Everyday decorative pieces in low-light spaces → Standard glass is fine
• Photos and prints in normal living spaces → UV glass is the smart choice
• Fine art in bright rooms or near windows → Anti-reflective UV glass
• Original artworks, heirlooms, anything irreplaceable → Museum or conservation glass
