The question “How long does a GRC house last?” is quite common among those planning to buy a modular prefabricated home. Typically, modular prefab houses use sandwich panels as their main component. However, construction innovation has evolved, introducing modular buildings that utilize GRC boards.
Glass-Reinforced Concrete (GRC) board is a building component made from a mixture of cement and glass fibers. This material is known for being practical, strong, and weather-resistant. When combined with aluminum, PVC, or other framing systems, GRC boards can be connected using structural joint systems to form durable modular buildings.
Here are some key advantages of GRC boards:
- Lightweight, making them easy to handle and transport.
- High strength-to-weight ratio compared to other materials.
- Resistant to extreme weather conditions, termites, and mold.
- Fire-resistant and non-combustible.
- Low maintenance and corrosion-free.
- Flexible for various architectural designs.
- Impact-resistant and not easily brittle.
- Waterproof even with relatively thin thickness.

How Long Does a GRC House Last?
A GRC house is claimed to last up to 25 years, depending on the durability of the GRC board used as its main building component.
Made from a mixture of cement and glass fibers, GRC is resistant to water, fire, and impact, making it less prone to cracking or breaking. Its strength allows it to withstand strong winds and seismic vibrations. Additionally, GRC boards are proven to resist termites, decay, mold, and humidity, ensuring long-lasting structural reliability and minimal maintenance needs.
Advantages of GRC Houses
When considering how long does a GRC house last, it is important to understand the advantages that make this type of building durable and efficient. A GRC house offers several key benefits:
- Lightweight yet Strong: GRC panels have an excellent strength-to-weight ratio, making them easier to transport and install while maintaining structural stability.
- Weather and Fire Resistant: GRC is highly resistant to extreme temperatures, heavy rain, and fire, ensuring long-term durability in various climates.
- Low Maintenance: The material does not corrode, warp, or require frequent repainting, making it cost-effective over time.
- Termite and Mold Resistant: GRC boards are immune to pest infestations and fungal growth, which extends the lifespan of the house.
- Design Flexibility: GRC can be molded into various shapes and finishes, allowing for aesthetic freedom and modern architectural designs.
- Eco-friendly: With its long lifespan and low maintenance requirements, GRC contributes to sustainable and environmentally responsible construction.

Are Sandwich Panel Houses as Good as GRC Houses?
Both sandwich panel houses and GRC houses are built using a knock-down or modular construction system, which allows for easy assembly and disassembly. The main difference lies in the materials used. A sandwich panel house utilizes sandwich panels as its core component, while a GRC house uses GRC boards.
These two materials may serve a similar function in modular construction but have distinct characteristics. Below are several key differences that help determine which option best suits your needs when considering how long does a GRC house last and its overall performance compared to sandwich panel structures.
Sandwich Panel
- Its structure consists of three layers, with the middle layer serving as thermal and sound insulation.
- It is easy to install.
- Durable with minimal maintenance required.
- Relatively affordable in terms of cost.
- Provides excellent thermal insulation.
- Fire-resistant for enhanced safety.
- Air- and water-tight for better protection.
- Creates a quiet and comfortable indoor environment.
- Environmentally friendly and energy efficient.
GRC Board
- Its structure is made from a mixture of cement and glass fibers.
- Practical, strong, and highly resistant to weather conditions.
- Long-lasting because the glass fibers are not easily damaged by corrosion.
- Performs well in various weather conditions.
- Waterproof even though the material is relatively thin.
- Fire-resistant, providing added safety and durability.
From the comparison above, both materials clearly share similar advantages, making either option a reliable choice for a prefabricated home.
