These photos were taken on the weekend. It's great to see the ground floor hebel has almost been finished. Only some of the walls facing east remain to be completed. We really like hebel as a product. It should look clean, sharp and modern when fully rendered.
Hebel is lightweight steel-reinforced autoclaved aerated concrete. The hebel is supplied in large blocks which are attached to metal studs with bolts. The photo below shows two of these metal studs (running horizontal underneath the window). Hebel as an external cladding is supposedly easier to work with than bricks and therefore much quicker to install than laying bricks. We are told that using hebel as our external cladding will shorten the overall build period. Coupled with the other documented benefits of hebel (highly fire resistant, high acoustic absorption, excellent insulative properties), we are very glad CG use hebel as a standard inclusion rather than a paid upgrade.
CSR Building Products Limited manufacturers Hebel. They produce a Design & Installation Guide that describes the benefits, design approach and considerations when using hebel (and specifically hebel powerblocks) for your home. If you are using or considering to use hebel for your home, we would recommend being familiar with this guide.
