Celcrete 50mm AAC Panels – Aerated Autoclaved Concrete Cladding System
Celcrete 50mm Aerated Autoclaved Concrete (AAC) panels form a lightweight, durable cladding system engineered for New Zealand’s climate and building requirements. Fire-rated, weather-resistant, and low-maintenance, Celcrete AAC panels provide seamless, high-performance exterior finishes designed to stand the test of time.
Designed for residential and lightweight commercial projects, Celcrete AAC panels deliver exceptional thermal insulation, acoustic performance, and impact resistance. This makes them ideal for homes and architectural builds where every detail counts. The panel system is easy to install, helping reduce construction time while maintaining long-term durability and structural integrity.
With a wide range of plaster finishes and colour options – including Novacolor Venetian plaster – the Celcrete AAC panel system allows architects, builders, plasterers and homeowners to achieve modern concrete-look finishes, textured façades, or fully bespoke designs. Backed by BRANZ appraisal and New Zealand Building Code compliance, the system combines aesthetic flexibility with trusted performance.
Whether you’re recladding, building new, or specifying a high-quality exterior solution, Celcrete AAC panels provide a cost-effective, sustainable, and architecturally trusted cladding system tailored to New Zealand conditions.

Fire Safety
Durable
Celcrete AAC panels are a durable, low-maintenance lightweight concrete cladding system that exceeds the minimum durability requirements of the New Zealand Building Code.
The system will not warp, rust, or rot, and is resistant to decay, insect damage, and impact under normal conditions. Proven performance on Christchurch homes following the 2010 and 2011 earthquakes demonstrates the long-term resilience of the Celcrete AAC cladding system.
Cost-Effective AAC Panel System
Celcrete AAC panels provide a cost-effective lightweight concrete cladding system by reducing both material complexity and construction time compared to other methods.
With simplified installation, the Celcrete AAC Panel System streamlines the build process, helping reduce labour costs and on-site handling. When projects are designed to suit panel dimensions, cutting and material waste are minimised, improving efficiency and lowering overall construction costs.
This streamlined approach also supports faster, simpler installation, contributing to improved builds without compromising durability or performance.
Environmentally Responsible AAC Panels
Celcrete AAC panels are an inert, natural cladding material manufactured using abundant raw materials and an energy-efficient production process. Trimming waste is recycled back into manufacturing, minimising waste and environmental impact. As a non-hazardous material, AAC does not emit harmful gases or vapours, supporting healthier, more sustainable building.
Fire Resistant AAC Panels
Celcrete AAC panels are non-combustible and do not release toxic gases, smoke, or burning droplets in a fire. With zero ignitability, AAC significantly delays fire spread. Fire resistance ratings of up to four hours exceed typical residential and commercial requirements, delivering robust fire protection within a lightweight concrete panel system.
Moisture-Resistant AAC Panel System
Celcrete AAC panels feature a closed-cell internal structure made up of millions of small, independent air pockets, resulting in low water absorption and excellent moisture resistance.
When installed as part of the Celcrete 50mm Panel Veneer System and finished with the Rendertek Plaster System, the system meets the weathertightness requirements of New Zealand Building Code clause E2.3.2. This integrated approach provides reliable moisture management and long-term protection against water ingress in New Zealand’s varied and demanding climate.
Sound Absorption & Acoustic Insulation
Celcrete AAC panels provide effective acoustic insulation by reducing the transmission of external noise through the building envelope.
Due to their mass and cellular internal structure, AAC panels offer superior sound insulation compared to many materials of similar weight, helping create quieter, more comfortable residential and commercial spaces.
Strong & Lightweight
Celcrete AAC panels combine low weight with high strength, expanding during manufacture to create a material approximately one-fifth the weight of standard concrete. Reinforced with corrosion-protected steel mesh and installed as part of the Celcrete Panel Veneer System, they meet New Zealand Building Code requirements for dependable structural performance
