Acrylic Glass or Plexiglass for Construction
Acrylic glass, colloquially known as plexiglass, is a lightweight and shatter-resistant engineering plastic that serves as an alternative to traditional glass. Its high impact resistance and ease of handling make it a popular choice for construction and architectural applications. It is used for everything from windows, walls, lighting fixtures, and canopies.
This article delves into the material's properties and its prevalent use across different industries.
Acrylic is readily available in sheets of various thicknesses, as well as in forms like rods, tubes, frosted, mirrored, or non-glared versions. Its versatility extends to different shapes, colors, and sizes.
While acrylic is often categorized as a type of glass, it is fundamentally a non-crystalline vitreous substance. It boasts excellent optical clarity, scratch resistance, strength, and toughness, all while remaining lightweight. Its density ranges from 1.17 to 1.20 g/cm³, which is less than half that of traditional glass.
With a 3mm thickness, acrylic glass transmits approximately 92% of visible light and possesses the capability to filter out ultraviolet (UV) light rays with wavelengths below 300 nm. Moreover, the light absorption and transmission characteristics can be adjusted by incorporating additives or coatings into PMMA, making it highly versatile for various construction applications.
Let's discuss the various types of acrylic glasses:
Clear acrylic sheets are used in applications where transparency is essential. They are widely used in windows, aquariums, display cases, and protective barriers. These are available in various thicknesses, widths, and lengths, making them versatile for different projects. They offer exceptional clarity and are highly durable.
It is used for applications requiring opacity, such as signage, privacy partitions, and light-sensitive displays that change color with lighting.
White acrylic sheets have the ability to transition from black to white under LED lighting making it a unique choice. It provides a balance between opacity and aesthetics.
Colored acrylic sheets come in a variety of vibrant hues, adding a splash of color to projects. They retain the same acrylic durability.
They are used for decorative elements, creative designs, and applications where both color and strength are important, such as art installations and architectural features.
They have a range of available colors that allow for customization and artistic expression. Fluorescent acrylic sheets even have glowing corners in the light.
