The Dilemma: Clarity or Tradition?
When you are framing your University Diploma, your Wedding Vows, or that limited edition poster, you face a choice: Glass or Acrylic?
For decades, glass was the default. Today, galleries, museums, and high-end interior designers are shifting en-masse to Acrylic (PMMA).
Why? Is it just a trend, or is it actually better?
In this guide, we break down the physics, economics, and aesthetics of the debate.
1. Visual Clarity: The "Green Tint" Problem
This is the biggest shock for most buyers.
- Glass: Standard window glass contains Iron Oxide. If you look at the edge of a glass pane, you will see a distinct Green Tint. This tint acts like a filter over your photo, subtly dulling whites and altering colors.
- Acrylic: Premium Cell Cast Acrylic (like we use at Aarohi) allows 92% Light Transmission. This is optically pure. There is no tint. Your black-and-white photos look sharper, and your colors look vibrant.
2. Safety: The "Shatter" Factor
- Glass: It is heavy and brittle. If a glass frame falls, it explodes into dangerous shards. This makes it a liability in:
- Children's Bedrooms
- Schools
- Earthquake-prone areas
- Public Hallways
- Acrylic: It is a thermoplastic. It is 10-20x more impact resistant than glass. If you drop it, it might chip, but it won't shatter.
3. Weight: Saving Your Walls
- Glass: A large A1 glass frame is incredibly heavy. You need serious wall anchors, stud finders, and often two people to hang it.
- Acrylic: It weighs roughly 50% less than glass of the same thickness. You can often hang medium-sized acrylic frames with adhesive strips (though we recommend standoffs for the best look).
4. Cost: Why is Acrylic More Expensive?
You might assume plastic is cheaper than glass. For cheap styrene, yes. For Cast Acrylic, no.
- Manufacturing: Producing optical-grade PMMA sheeting is an energy-intensive industrial process.
- Polishing: A glass edge can be rough. An acrylic edge must be diamond polished to be presentable.
- Verdict: You pay more for acrylic, but you are paying for longevity and optical superiority.
5. Maintenance: The "Scratch" Risk
Here is the one area where Glass wins.
- Glass: Very hard to scratch. You can wipe it with anything.
- Acrylic: Softer than glass. If you wipe it with a rough paper towel, you will induce "swirl marks." You MUST use a Microfiber Cloth.
Conclusion: Which Should You Buy?
- Buy Glass If: You are on a strict budget and the frame will hang in a low-traffic adult area.
- Buy Acrylic If: You want the best possible visual clarity, safety for kids/pets, or are framing a large piece (A2+).
