Is GRC Suitable for Interior Decoration? Technical Analysis of GRC Interior Applications

GRC is not only fully suitable for interior decoration; its Class A fire resistance, eco-friendly formaldehyde-free composition, design freedom, and rich textures give it unique advantages in modern interior design, especially in projects such as high-end commercial spaces, cultural venues, and hotels. Through refined adjustments to material formulations and innovations in surface treatment technology, Qinglong GRC provides interior spaces with safe, beautiful, and artistically expressive decorative solutions.

In the interior spaces of the Bulgari Hotel Shanghai, the interior application of Qinglong GRC is showcased to the fullest. The curved artistic wall in the hotel lobby uses ultra-thin white GRC panels with finely polished and matte-treated surfaces, presenting a warm, jade-like texture. The hollow-out screens in the guest room areas feature flowing patterns generated through parametric design, ensuring spatial privacy while introducing graceful plays of light and shadow. These GRC elements not only enhance the spatial quality visually, but their environmental performance has also passed stringent indoor air quality tests, with formaldehyde and TVOC emissions below detection limits, fully meeting the health requirements of high-end hotels. The GRC materials used in the project achieve Class A combustion performance, providing guests with the highest level of fire safety protection.

Outstanding Fire Safety

GRC is an inorganic non-combustible material with Class A (A2) combustion performance and releases no toxic fumes when exposed to fire. This property gives it an irreplaceable advantage in the interior decoration of crowded public places such as theaters, shopping malls, schools, hospitals, and transportation hubs, fully complying with the most stringent fire codes.

Excellent Environmental and Health Performance

Qinglong GRC uses inorganic raw materials such as cement, sand, and glass fibers, eliminating pollution from formaldehyde, benzene, and other volatile organic compounds at the source. The radionuclide limits of the products meet the national Class A decoration material standard, with no restrictions on their scope of use. Their dense surfaces resist mold growth and are easy to clean, helping to create a healthy indoor environment.

Rich Decorative Expressiveness

The shapes and textures achievable with interior GRC far exceed those of traditional materials. Whether shaping overall curved ceilings and delicate relief walls, or producing hollow-out light-transmitting partitions and stone- or wood-effect decorative elements, GRC can achieve them all with precision. Surfaces can be treated with a variety of finishes such as glossy, matte, sandblasted, stone-effect, metal-effect, and wood-grain, while colors can be freely customized with inorganic pigments.

Good Acoustic and Physical Performance

GRC materials offer a degree of sound absorption; by laminating sound-absorbing cotton on the back or designing porous structures, their sound absorption coefficient can be further improved, making them suitable for acoustically demanding spaces such as concert halls and lecture halls. Their thermal inertia also helps regulate indoor temperature and enhance comfort.

In the field of interior decoration, GRC is transforming from a “substitute material” into a “creative material.” It liberates designers’ imagination, freeing interior spaces from the limitations of material workability. Qinglong GRC is committed to injecting a unique soul into every interior space through the combination of technology and art.
