At GC Products, we create any architectural product that you need to make your dreams a reality, specializing in both GFRG and GFRC. One of the products that is often requested from our team is a barrel vault ceiling – an arched ceiling with a design that looks similar to a barrel that has been cut in half.
Glass Fiber Reinforced Gypsum (GFRG) is an ideal material for constructing barrel vault ceilings in both commercial and institutional settings. Its combination of strength, lightweight composition, and precision fabrication makes it especially well-suited for curved architectural forms that require dimensional accuracy and minimal on-site finishing.
Why Choose GFRG for Barrel Vault Ceilings?
Barrel vault ceilings can be designed with many materials, including wood, stone, and concrete. But GFRG is often one of the best choices. That is because it offers:
Dimensional Accuracy for Curved Forms
GFRG is cast in molds under controlled conditions, allowing for consistent replication of complex geometries. For barrel vaults, which depend on precise curvature and smooth transitions, GFRG ensures the design intent is maintained throughout the installation, with benefits that include:
- Tolerances are tightly controlled during fabrication
- Seamless joints can be achieved with minimal on-site adjustments
- Accurate alignment reduces the need for field corrections
This is something typically not possible with many other materials, as even common materials like wood may not be as precise, making it difficult to install.
Lightweight Yet Structurally Sound
Despite its rigidity, GFRG is significantly lighter than traditional gypsum or plaster assemblies. This reduces the structural load on the ceiling framework and allows for easier handling during installation. It offers:
- Lighter sections mean reduced framing requirements
- Lower installation labor costs compared to traditional plaster systems
- Decreased risk of cracking or structural stress over time
GFRG is one of the few products that can be installed efficiently while also helping enhance the longevity of the entire structure.
Smooth, Monolithic Appearance
GFRG panels can be fabricated to create long, uninterrupted spans, ideal for achieving the monolithic appearance desired in barrel vault ceilings. Joints can be reinforced and finished to create a seamless finish. It provides:
- Continuous visual flow across curved surfaces
- No visible seams when properly finished
- Paint-ready surface with minimal skim coating
Keep in mind that GFRG can also be customized for texture, so if you do prefer a specific look, we can provide that as well.
Integration with Other Systems
Barrel vault ceilings often incorporate lighting, HVAC, or acoustic elements. GFRG panels can be fabricated with cut-outs or integration features to accommodate these systems without compromising the surface integrity. Benefits include:
- Pre-engineered access points reduce coordination errors
- Compatible with embedded hardware or mounting systems
- Supports both aesthetic and functional ceiling components
Since barrel vaulted ceilings are typically installed with major overhauls of existing buildings, or in brand new properties, the ability to adjust and adapt to other needs is highly beneficial.
Fire-Resistant and Non-Combustible
As a gypsum-based product, GFRG offers inherent fire resistance and is classified as non-combustible. This makes it a preferred material for public buildings, healthcare facilities, and areas where fire performance is a design consideration. GFRG:
- Meets ASTM E84 Class A flame spread requirements
- Does not emit toxic fumes under high heat
- Complies with IBC and NFPA guidelines for interior finishes
This makes it a safer option, especially in areas where there might be fire risk.
Long-Term Dimensional Stability
Unlike traditional plaster, GFRG does not shrink or crack due to temperature or humidity changes. This stability is particularly advantageous in large-span ceilings where environmental variations could affect the integrity of more traditional materials. This is a huge benefit, as it:
- Maintains shape and form over time
- Resistant to expansion, contraction, and sagging
- Reduces maintenance and repair needs over the lifecycle
Architects love GFRG because it is often a “Set it and Forget it” material, one that the building owners typically do not have to worry about after installation.
