GC Products LLC creates a lot of column covers. It is one of our most commonly requested products, as columns remain one of the most popular and widely needed architectural elements available today. We create column covers for both interior and exterior architectural designs, and it is perhaps not surprising that the material changes depending on whether it’s indoors or outdoors.

Exterior column covers are typically made in Glass Fiber Reinforced Concrete (GFRC), while interior column covers are created with Glass Fiber Reinforced Gypsum (GFRG). The most common reason for this is waterproofing, as GFRC is more resistant to the elements than GFRG, despite GFRG being extraordinarily durable in its own right. Still, those are not the only reason that we use these materials in different places.

Benefits of GFRG for Interior Applications

Both materials are outstanding, but if you had to choose one, you would probably go with GFRG. That is because GFRG is:

  • Lightweight and Easy to Install – GFRG column covers are lightweight compared to traditional materials like stone or wood, making them easier to handle during installation. This results in reduced labor costs and faster installation times.
  • Customizable Design – GFRG can be easily molded into a variety of shapes and sizes, making it ideal for interior projects that demand complex, decorative column designs. Architects can use GFRG to create smooth, seamless finishes or intricate ornamental details that blend perfectly with the overall interior design scheme.
  • Seamless Surface Finishes – Since GFRG offers a smooth and refined surface, it requires minimal finishing work. This is particularly beneficial for interior projects where aesthetics are critical, allowing column covers to integrate seamlessly with surrounding wall surfaces or ceilings.
  • Fire Resistance – GFRG has natural fire-resistant properties, making it a safe choice for interior applications. It provides an additional layer of protection against fire hazards, which is essential in high-traffic interior spaces such as commercial buildings, lobbies, and atriums.
  • Eco-Friendly – GFRG is considered a sustainable material due to its low environmental impact during both manufacturing and disposal. Its gypsum base is recyclable, making it an environmentally friendly option for eco-conscious interior designers and architects.

GFRC has many of these same benefits, but not to the degree of GFRG, especially with regards to how lightweight it is. GFRG is one of the lightest weight, most durable materials out there, and many architects and contractors love using it for their projects.

GFRC Column Covers for Exterior Projects

Still, GFRG is not right for all projects. GFRC, or Glass Fiber Reinforced Concrete, is a composite material that combines cement, sand, water, and glass fibers. Its durability and weather resistance make it an excellent choice for exterior column covers, and it does have its own benefits that can be especially useful for outdoor projects. These include:

  • Superior Strength and Durability – GFRG is strong, but GFRC is stronger, providing excellent durability and resistance to impact. This makes it ideal for exterior applications where columns may be exposed to environmental factors such as wind, rain, and physical wear.
  • Weather Resistance – One of the primary benefits of GFRC is its ability to withstand harsh weather conditions. It is resistant to water, UV radiation, and temperature fluctuations, which ensures that GFRC column covers maintain their structural integrity and appearance over time, even in challenging climates.
  • Low Maintenance Requirements – GFRC is highly durable and resistant to cracking, which means it requires minimal maintenance. This is a critical advantage for exterior projects, where frequent maintenance can be costly and disruptive. The material’s longevity ensures that column covers remain aesthetically pleasing without extensive upkeep.
  • Customizable for Exterior Designs – Similar to GFRG, GFRC can be molded into a wide range of shapes and finishes. This versatility allows architects to create custom designs that enhance the exterior of a building. From modern, minimalist designs to ornate, classical columns, GFRC can be used to achieve various architectural styles.
  • Lightweight for Structural Efficiency – Despite its strength, GFRC is relatively lightweight compared to traditional concrete. This reduces the load on the building’s structure, making it easier to incorporate GFRC column covers into complex exterior designs without compromising structural integrity.
  • Fire and Impact Resistance – GFRC’s fire resistance, combined with its ability to withstand impact, makes it a robust choice for exterior column covers. This is particularly important for public or commercial buildings where safety is a top priority.

It is heavier than GFRG, and thus takes a bit more manpower to install, but it is still an excellent option – especially for exterior column covers.

Comparing GFRG and GFRC for Interior vs. Exterior Applications

While both GFRG and GFRC offer design flexibility and customization, their optimal applications differ due to their inherent material properties.

Why GFRG Is Ideal for Interiors:

  • Lightweight and easy to install in spaces where structural load is a concern.
  • Provides smooth, seamless finishes for decorative and aesthetic purposes.
  • Naturally fire-resistant and environmentally friendly, making it a practical and safe option for interior spaces.

Why GFRC Is Suited for Exteriors:

  • Offers superior strength and weather resistance, critical for outdoor conditions.
  • Requires minimal maintenance and withstands the environmental elements without deteriorating.
  • Combines durability and aesthetic versatility, allowing for robust yet visually appealing exterior column designs.

The choice between GFRG and GFRC for column covers depends on the specific needs of your project. GFRG excels in interior environments, providing lightweight, customizable, and fire-resistant options that enhance aesthetic appeal without compromising safety. On the other hand, GFRC is the material of choice for exterior projects, where durability, weather resistance, and minimal maintenance are paramount.
