GRC is a lightweight alternative to traditional concrete that retains many of its benefits.
It offers versatility in shape, size, and finish, allowing for bespoke designs that meet your vision and planning needs—all without the structural load of conventional concrete. GRC can be up to 80% lighter than standard precast cladding while maintaining strength and durability.
Why Choose GRC?
Lightweight & Durable
GRC is easier to handle and install than traditional concrete, thanks to its significantly lighter weight. Despite this, it remains highly durable, with excellent resistance to cracking and weathering.
Design Flexibility
GRC can be moulded into intricate, custom designs, offering aesthetic versatility for both modern and traditional styles without the bulk of solid materials.
Weather Resistance
Its resistance to environmental factors like rain, wind, and freeze-thaw cycles makes GRC ideal for exterior applications, ensuring long-lasting facades.
GRC in Rainscreen Systems
GRC is also well-suited as outer cladding in rainscreen systems, protecting buildings from moisture and enhancing energy efficiency. As part of these systems, GRC forms the first line of defence against the elements while delivering an attractive finish.
Ventilated Cavity
A ventilated cavity behind the GRC panels promotes air circulation and drainage, preventing moisture from reaching the internal structure and reducing the risk of water damage.
Energy Efficiency
By incorporating insulation and waterproof membranes, GRC-based rainscreen systems enhance thermal performance, helping to regulate temperature and reduce energy costs.
GRC in EWI (External Wall Insulation)
GRC is often used as the outer cladding in External Wall Insulation (EWI) systems, providing a durable and weather-resistant finish, while insulation materials such as mineral wool handle thermal performance. How GRC Integrates with EWI:
Protective Cladding
Shields insulation from environmental exposure, offering long-term durability.
Lightweight & Flexible
Lighter than traditional concrete, simplifying installation and design versatility.
Mechanical Fixing
Typically fixed to a subframe or structure, ensuring stability.
Compatibility
Works well with a range of insulation materials and enhances fire resistance.
Aesthetic Versatility
Can mimic stone, wood, or other finishes for design flexibility.
GRC is used across residential, high-rise, and commercial buildings for its fire resistance, lightweight nature and architectural flexibility.
Benefits of GRC for Your Project
Design Versatility
GRC opens up creative possibilities, from natural stone effects to unique textures and finishes.
Sustainability
With reduced raw material usage compared to traditional concrete, GRC supports more sustainable building practices.
Long-Term Durability
GRC panels are designed to withstand challenging weather conditions, offering long-lasting strength and low maintenance.
