Karp's GFRG Glass Fiber Reinforced Gypsum Access Door provides concealed access to building services while maintaining a consistent drywall ceiling appearance. Manufactured from glass fiber reinforced gypsum, the panel is designed to blend with the surrounding ceiling surface after installation and finishing.
Unlike conventional steel access doors with exposed metal faces, the GFRG door uses a gypsum surface that can be finished to coordinate with the surrounding drywall. It provides a discreet access point for maintenance and inspection in commercial and residential interior projects.
The GFRG access panel is designed for projects where visible access doors would interrupt the appearance of a finished drywall ceiling.
Its glass fiber reinforced gypsum construction allows the door surface to integrate with the surrounding ceiling finish. Once installed and finished, the panel is concealed within the ceiling plane while retaining access to building services above.
Key product features include:
Glass fiber reinforced gypsum construction
Designed for drywall ceiling installations
Concealed appearance after finishing
Five standard door sizes
Suitable for new construction and ceiling access applications
The GFRG is designed for drywall ceilings where a concealed service opening is required.
Typical applications include:
Commercial office ceilings
Hotel and hospitality interiors
Multi-family residential buildings
Institutional interiors
Finished drywall ceilings requiring discreet maintenance access
The panel provides access to concealed plumbing, electrical, mechanical and other building services. Select the appropriate size based on the equipment or service that must be reached.
The GFRG is available in five standard sizes. The ceiling opening is 6 inches larger than the nominal door size in both dimensions.
