When you take a beloved photograph, a valuable piece of original art, or a cherished diploma to be framed, you’re likely thinking about the frame molding and the mat board. But there’s a third, equally critical component that often goes overlooked until the very end: the glazing, more commonly known as the glass.
The glass you choose does more than just keep the dust off. It affects how you view the art, how much glare distracts from the image, and, most importantly, how well your piece is protected from the damaging effects of light over time.
Let’s break down the different types of framing glass and acrylic available so you can make the best choice for your next framing project!
1. Standard Clear Glass (Premium Clear)
Standard clear glass is the most basic option available in custom framing. It protects your artwork from physical damage, dust, and moisture.
The Pros:
- Cost-effective: This is the most affordable glazing option.
- Scratch-resistant: Like most glass, it handles standard cleaning without scratching easily.
The Cons:
- High Glare: Standard glass reflects a significant amount of light, which can make it hard to see your artwork in brightly lit rooms.
- No UV Protection: It blocks only about 45% of UV rays, meaning your artwork is susceptible to fading and paper discoloration over time.
Best for: Easily replaceable posters, inexpensive prints, or items hung in dimly lit rooms away from natural sunlight.
2. Non-Glare Glass
If you have a room with lots of windows or overhead lights, glare can ruin the viewing experience. Non-glare glass is etched on one side to diffuse light, significantly reducing reflections.
The Pros:
- Reduces Reflections: Spreads light out to minimize distracting glare.
- Affordable: A step up from standard glass but still budget-friendly.
The Cons:
- Softens the Image: Because of the etched surface, it can make the artwork look slightly fuzzy or muted, especially if there are multiple mat boards separating the art from the glass.
- No UV Protection: Like standard glass, it does not protect against fading.
Best for: Inexpensive pieces that must be hung in highly reflective environments.
3. Conservation Clear Glass (UV Blocking)
Light damage is cumulative and irreversible. UV rays from the sun and even fluorescent indoor lighting can fade colors and cause paper to become brittle and yellow. Conservation Clear glass is coated to block 99% of harmful UV light.
The Pros:
- Excellent Protection: Keeps your art vibrant and safe from light damage.
- Clear Viewing: Maintains the crispness and clarity of the artwork.
The Cons:
- Glare: It reflects light just as much as standard clear glass.
Best for: Original artwork, limited edition prints, sentimental items, and anything of value that you want to preserve for generations.
4. Conservation Non-Glare Glass
This option combines the etched, light-diffusing surface of standard non-glare glass with the 99% UV-blocking coating of Conservation Clear.
The Pros:
- Dual Benefit: Protects against fading while reducing distracting room reflections.
The Cons:
- Softens the Image: Just like standard non-glare, the etching can slightly blur the crispness of the art, particularly when spaced away from the image.
Best for: Valuable pieces displayed in bright, reflective environments where glare is an issue but preservation is a must.
5. Museum Glass
If you want the absolute best for your artwork, Museum Glass is the gold standard. Instead of being etched to diffuse light (which causes fuzziness), Museum Glass has a specialized anti-reflective coating—similar to the coating on high-end prescription eyeglasses. It also boasts 99% UV protection.
The Pros:
- Nearly Invisible: The anti-reflective coating makes the glass seem like it’s not even there, allowing the true colors and textures of the art to pop.
- Maximum Protection: 99% UV blocking keeps your art safe.
The Cons:
- Cost: This is a premium product and comes with a higher price tag.
- Shows Smudges: Oils from fingerprints show up easily, requiring careful handling and specific cleaning methods (usually just a microfiber cloth and ammonia-free cleaner).
Best for: High-value art, original paintings, deeply shadowboxed items, and highly detailed pieces where clarity is paramount.
What About Acrylic (Plexiglass)?
While glass is traditional, acrylic (often called Plexiglass) is a fantastic alternative and is sometimes the better choice. Acrylic is available in most of the same finishes as glass (Standard, Non-Glare, UV-Blocking, and Anti-Reflective, such as Optium Museum Acrylic).
The Pros:
- Lightweight: Weighs about half as much as glass, making it essential for oversized frames.
- Shatter-Resistant: Won’t break into dangerous shards, making it ideal for art shipped by mail, hung in children’s rooms, or used in earthquake-prone areas.
The Cons:
- Prone to Scratching: Acrylic scratches much more easily than glass, meaning you must be very careful when cleaning it (never use paper towels or glass cleaners with ammonia).
- Static: It holds a static charge, which can attract dust or pull loose media (like pastels or charcoal) off the paper.
The Final Verdict
When choosing your framing glass, ask yourself three questions:
- Is the piece valuable or sentimental? If yes, always choose a UV-filtering option (Conservation Clear or Museum).
- Where will it hang? If it’s directly across from a window, consider Museum Glass or Non-Glare to combat reflections.
- How big is it? If the piece is massive, you may need to switch to Acrylic for safety and weight considerations.
Investing in the right glazing ensures that your framed pieces not only look stunning on your wall today but will remain vibrant and protected for a lifetime!
