Plexiglass vs. Acrylic Sheets – What’s the Difference?

In the world of transparent thermoplastics, two terms often surface interchangeably: plexiglass and acrylic sheets. Whether you are shopping for window replacements, tabletop covers, DIY crafts, or professional displays, understanding these materials can help you make the right buying decision.

At Fab Glass and Mirror, we specialize in high-quality custom plexiglass and acrylic glass sheets customized for various residential, commercial, and industrial applications. This comprehensive buying guide explains the differences between plexiglass and acrylic sheets, their uses, and how to choose the right option for your needs.

What Is Plexiglass?

Plexiglass is a trade name for polymethyl methacrylate (PMMA), a type of clear plastic used as a lightweight and shatter-resistant alternative to glass. The term originated from the brand “Plexiglas,” which popularized this durable material.

Key Properties of Plexiglass:

• High optical clarity
• UV-resistant (especially in exterior-grade variants)
• Lightweight yet strong
• Shatter-resistant
• Easy to cut and shape

Common Applications:

• Home windows and storm panels
• Protective barriers and sneeze guards
• Greenhouse panels
• Signage and retail displays
• Picture frame covers

At Fab Glass and Mirror, our custom plexiglass sheets are ideal for projects requiring exact sizing and clarity.

What Are Acrylic Sheets?

Acrylic sheets are also made of PMMA, just like plexiglass. The key difference is that “acrylic” is the generic term, while “plexiglass” refers to branded or colloquial use.

Types of Acrylic Sheets We Offer:

• Clear acrylic sheets
• Colored plexiglass sheets
• Textured or frosted acrylic sheets
• UV-filtering and impact-resistant sheets

Typical Applications:

• Acrylic table tops and surface protectors
• Acrylic picture frames
• Custom acrylic windows
• Acrylic pen holders
• Custom acrylic shelving

These sheets are lightweight, easy to fabricate, and widely used in interior design, art installations, and commercial signage.

Is There a Real Difference Between Plexiglass and Acrylic Sheets?

Yes and no. Think of it this way: all Plexiglass is acrylic, but not all acrylic is Plexiglass. Here’s a breakdown to clarify:

Feature	Plexiglass	Acrylic Sheets
Brand/Trademark	Yes (Plexiglas® by Röhm)	No. Generic material name
Cost	Often branded pricing	More affordable options available
Availability	Limited formats based on brand supply	Wide range of sizes, colors, finishes
Custom Options	Limited	Extensive with Fab Glass and Mirror
Use Cases	Specialty & architectural projects	Residential, retail, DIY, signage

When to Choose Plexiglass Over Acrylic Sheets

While both are suitable for most applications, there are scenarios where one may be better than the other:

Choose Plexiglass if:

• You are fulfilling architectural specs that require branded material.
• You need optical-grade clarity for high-end photography.
• You’re working on museum display cases with precise standards.

Choose Acrylic Sheets if:

• You want cost-effective material for a wide range of uses.
• You require custom sizes, colors, or laser-cut shapes.
• You’re a DIYer, designer, or homeowner looking for flexibility.
