Acrylic signs, such as house number signs, have become a popular choice for both residential and commercial properties. Known for their durability, versatility, and aesthetic appeal, these signs are ideal for displaying home address numbers. But what makes them so resilient and appealing? To answer that, we need to delve into what acrylic is and how it’s crafted into the signs we see today.

Acrylic: The Material Behind the Sign

What is Acrylic?

Acrylic, often known by the brand names such as Plexiglas or Perspex, is a type of plastic known as polymethyl methacrylate (PMMA). It is a synthetic polymer created from the monomer methyl methacrylate. Now, that’s a lot of scientific jargon, but in layman’s terms, acrylic is a type of plastic made by a chemical reaction involving petroleum products.

Key characteristics of acrylic include:

  • Highly Durable: Acrylic is resistant to weather, which is why it’s commonly used for outdoor applications like house signs.
  • Clear & Colorful: Acrylic can be transparent, translucent, or opaque, and it can come in any color, making it incredibly versatile for custom house numbers.
  • Lightweight: Despite its durability, acrylic is lighter than glass, which makes it easier to install and handle.

How is Acrylic Made?

Acrylic is made through a process called polymerization. In simple terms, this involves using heat to trigger a chemical reaction that turns a liquid monomer into a solid polymer. The end result is a clear, hard plastic that’s perfect for making address numbers and signs.

The Making of Acrylic Signs

From Raw Material to Finished Product

Making acrylic signs involves several steps:

  1. Casting: The acrylic sheet is cast from liquid acrylic that is then poured into a mold where it hardens.
  2. Cutting: Once the sheet is formed, it’s cut into the desired size using precision cutting tools.
  3. Printing/Engraving: The design, such as your house numbers Canada, is then printed or engraved onto the cut acrylic piece.
  4. Polishing: The edges of the sign are then polished for a clean, finished look.
  5. Mounting: Finally, the sign is equipped with mounting hardware, ready for DIY installation.

  • Customizability: Acrylic can be cut and shaped into any design, providing endless possibilities for custom address plaques.


Acrylic house number signs are a testament to the power of modern materials science. The production process, which transforms petroleum products into a clear, durable, and highly customizable material, has opened up a world of possibilities for homeowners and businesses alike.

Here’s a fun fact from Wikipedia: In the 18th century, it was common for London houses to have a sign displaying the house number attached to their gate posts, or railings. The house number was also engraved on the turrets of the houses.
