Hebel, also known as Autoclaved Aerated Concrete (AAC), is a versatile, lightweight, and sustainable building material that has been gaining popularity in the construction industry for its numerous benefits. Developed in Sweden in the 1920s, Hebel has become a preferred choice for residential, commercial, and industrial construction projects worldwide. This blog will delve into what Hebel is, its benefits, and a comparative chart highlighting its key characteristics.
What is Hebel?
Hebel is CSR’s brand of Autoclaved Aerated Concrete (AAC).
Hebel is available as panels and blocks and is easy to handle and cut. Hebel panels contain steel reinforcement for added strength and are available in a variety of sizes, depending on the application.
Hebel is strong, versatile and delivers a range of benefits including thermal and acoustic insulation, fire protection and faster construction. Plus, its uses a third of the energy to make compared to other masonry products.
What is AAC?
Autoclaved Aerated Concrete (AAC) is a lightweight, strong masonry product.
ACC was developed over 70 years ago in Scandanavia. Today, ACC is a mainstream building material in Europe, Japan, Russia, China, much of Asia and increasingly Australia.
AAC is manufactured using naturally available materials such as sand, cement, lime, gypsum and small amounts of aluminium. AAC is an energy efficient, environmentally friendly masonry product.
Benefits of Hebel
-
Energy Efficiency Hebel’s excellent thermal insulation properties make it an energy-efficient building material. The air pockets within Hebel blocks and panels reduce heat transfer, keeping interiors cooler in summer and warmer in winter. This can significantly reduce the need for heating and cooling, leading to lower energy bills and a reduced carbon footprint.
-
Fire Resistance One of the standout features of Hebel is its exceptional fire resistance. Being non-combustible, Hebel can withstand high temperatures and provide a fire rating of up to four hours, depending on the application. This makes it an ideal choice for buildings where fire safety is a priority.
-
Soundproofing The soundproofing qualities of Hebel are another major advantage. The material’s porous structure helps absorb sound, making it an effective sound barrier. This is particularly beneficial in multi-residential buildings and commercial spaces where noise reduction is important.
-
Lightweight Despite being a solid masonry product, Hebel is about 25% the weight of traditional concrete. This lightweight nature makes it easier to handle and faster to install, which can lead to reduced construction times and labor costs.
-
Cost-Effective While the initial cost of Hebel might be higher than some other materials, the long-term savings in energy costs, reduced labor, and faster construction times can make it a cost-effective choice.
-
Durability Hebel is a durable and robust material that can withstand harsh weather conditions without degrading. When installed correctly, it can last for many years, maintaining its structural integrity and appearance.
-
Pest Resistance Hebel is inorganic and does not provide a food source for termites or other pests. Its solid construction also eliminates cavities where pests might nest, providing an added layer of protection for buildings.
-
Non-Toxic Hebel products do not contain any toxic gases or substances, making them safe for use in all types of buildings, including homes, schools, and healthcare facilities.
-
Environmental Friendliness Hebel is an environmentally friendly building material. Its production requires less energy and emits fewer greenhouse gases compared to traditional masonry products. Additionally, its excellent insulation properties contribute to lower energy consumption in buildings.
-
Ease of Installation The lightweight and easy workability of Hebel means it can be quickly and efficiently installed on-site. It can be sawn, drilled, nailed, and machined with standard tools, making it a flexible option for builders.
