MaxiWall AAC Panels

[vc_row class=”container”][vc_column][vc_row_inner][vc_column_inner width=”1/2″][vc_column_text]

MaxiWall is a high-performance autoclaved aerated concrete (AAC) made from a blend of sand, lime, cement, and water. With an expansion agent added to the mix, MaxiWall rises during the manufacturing process, creating lightweight yet durable panels. Manufactured using advanced German technology that has been refined over 80 years, MaxiWall AAC panels offers a modern, efficient solution for building construction.

Installing just one MaxiWall AAC panel is equivalent to laying approximately 75 bricks, offering significant cost savings for both builders and homeowners. This not only reduces overall construction expenses but also lowers labour costs and minimises material wastage on-site.

When compared to traditional building materials like brick and block, MaxiWall has 60% less embodied energy and generates 50% fewer greenhouse gas emissions during production. This makes it an environmentally friendly and cost-effective alternative. MaxiWall can be easily installed by the same carpenters handling your wall frames and roof, allowing for streamlined construction and reduced timelines.

MaxiWall AAC panels are highly versatile, compatible with a wide range of façade materials such as fibre cement, timber, or steel, giving builders and homeowners flexibility in achieving their desired aesthetic.

Available at Big River branches across Australia, MaxiWall is built to withstand Australia’s tough environmental conditions. Steel-reinforced and coated with a render layer, MaxiWall is designed to resist the elements and deliver long-lasting durability, ensuring your structure remains strong for years to come.

Proven & Backed by Big River

AAC was invented in Sweden over 70 years ago and is widely used in building throughout Europe as well as other regions in the world. Its popularity amongst architects, builders and homeowners in Australia has been growing significantly over the past 20 years. Now available and supported in Australia through the established national sales and distribution network of the Big River Group.[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row]

[vc_row class=”container”][vc_column][vc_tta_accordion active_section=”1″][vc_tta_section title=”What is Autoclaved Aerated Concrete (AAC)?” tab_id=”faq1″][vc_column_text]AAC is a lightweight, precast concrete material made from a mixture of natural raw materials such as sand, lime, cement, water, and a small amount of aluminium powder. The aluminium reacts with the lime to form hydrogen gas, which creates air bubbles, making the concrete porous and lightweight. It is then cured under high pressure and temperature in an autoclave.[/vc_column_text][/vc_tta_section][vc_tta_section title=”What are the main benefits of AAC?” tab_id=”faq2″][vc_column_text]

• Lightweight: AAC is much lighter than conventional concrete, making it easier to handle and transport.
• Thermal Insulation: It has excellent thermal insulation properties, helping to reduce energy consumption in buildings.
• Fire Resistance: AAC is fire-resistant and can withstand high temperatures.
• Bal Rated: Maxiwall AAC is full FZ rated Re: Bush Fire attack Level. This makes it suitable for construction is the most extreme Bushfire Attack Level areas.
• Sound Insulation: It also provides good sound insulation, making it ideal for noise-sensitive buildings.
• Sustainability: It is made from eco-friendly materials and has a low environmental impact compared to traditional concrete.

[/vc_column_text][/vc_tta_section][vc_tta_section title=”Is AAC strong enough for structural use?” tab_id=”faq3″][vc_column_text]Yes, AAC is strong enough for structural applications. It is commonly used in walls, floors, and roofs. Its compressive strength can be adjusted depending on the mix ratio, with higher-density AAC used for load-bearing walls and lower-density AAC for non-load-bearing applications.[/vc_column_text][/vc_tta_section][vc_tta_section title=”How does AAC compare to traditional concrete?” tab_id=”faq4″][vc_column_text]AAC is lighter, more energy-efficient, and has better insulating properties than traditional concrete. While traditional concrete is stronger, AAC’s thermal and acoustic properties make it ideal for construction where insulation is important. AAC is also easier to cut and shape than traditional concrete, making it more versatile for certain applications.[/vc_column_text][/vc_tta_section][vc_tta_section title=”Is AAC environmentally friendly?” tab_id=”faq5″][vc_column_text]Yes, AAC is considered environmentally friendly, using natural materials with a low carbon footprint. The manufacturing process consumes less energy than traditional concrete, and the material is fully recyclable.[/vc_column_text][/vc_tta_section][vc_tta_section title=”How is AAC installed?” tab_id=”faq6″][vc_column_text]AAC blocks are typically installed using thin-layer mortar or adhesive, which reduces the need for large amounts of plaster or cement. They are easy to cut with standard tools, allowing for quick and precise installation. AAC is usually used in combination with other materials for structural reinforcement where necessary.[/vc_column_text][/vc_tta_section][vc_tta_section title=”Can AAC be used in all climates?” tab_id=”faq7″][vc_column_text]Yes, AAC performs well in most climates. Its thermal insulating properties make it suitable for both hot and cold climates, reducing the need for additional insulation materials. However, in very wet or high-moisture environments, AAC may require additional waterproofing to maintain its durability.[/vc_column_text][/vc_tta_section][vc_tta_section title=”Does AAC require maintenance?” tab_id=”faq8″][vc_column_text]AAC is low-maintenance due to its durability and resistance to pests like termites and mold. However, like any building material, it may require periodic inspections for signs of damage or wear, especially in areas with extreme weather conditions.[/vc_column_text][/vc_tta_section][vc_tta_section title=”What are the applications of AAC?” tab_id=”faq9″][vc_column_text]AAC is used in a variety of applications, including:

• Residential buildings (walls, floors, and roofs)
• Commercial buildings (walls, partitions, and facades)
• Load-bearing and non-load-bearing structures
• Insulating blocks for energy-efficient buildings
• Soundproofing for noise-sensitive areas

[/vc_column_text][/vc_tta_section][vc_tta_section title=”Is AAC fire-resistant?” tab_id=”faq10″][vc_column_text]Yes, AAC is highly fire-resistant. It can withstand temperatures up to 1200°C without losing its structural integrity, making it an excellent choice for fireproofing in buildings.[/vc_column_text][/vc_tta_section][vc_tta_section title=”How does AAC perform in terms of insulation?” tab_id=”faq11″][vc_column_text]AAC provides excellent thermal and sound insulation. Its porous structure helps to regulate temperatures inside buildings, keeping them cooler in summer and warmer in winter, which can lead to significant energy savings.[/vc_column_text][/vc_tta_section][/vc_tta_accordion][/vc_column][/vc_row][vc_row class=”custom-contact-strip”]
