Duplex Common Wall Material
There has been a lot of talk around this week in regards to the new CDC regulation being released. If you know have a 12m wide block and you compile with councils minimum lot sizes you will be able to do a duplex under a CDC approval in only 20 days.
Today I want to talk about the most common used Duplex Common Wall Material that you can use.
Before we get it to to the material I want to explain the main reason for this common wall is for fire separation. The Duplex Common Wall Material will have to provide the right amount of fire rating time to is required for your construction, this will vary depending on the development type you are undertaking.
Below are two Duplex Common Wall Material
One of the most commonly used materials used would be brick. This would generally be a 230mm think wall which is a double skin of brickwork continuing all the way up until the underside of the roof. Brick would have to be the most expensive Common Wall Material to use but would be considered to be the strongest. A standard duplex would take around 3days to complete.
Hebel products are made from a lightweight masonry called Autoclaved Aerated Concrete (AAC). This advanced technology produces extremely small, finely dispersed air pockets within the material. The result is
a lightweight aerated concrete which is strong and durable, but only about a quarter the weight of
conventional brick or concrete. This makes for a quick installation with a standard duplex taking about a day to complete.
I hope now you have a better understanding of Duplex Common Wall Material that can be used as a lot of you may be undertaking in a duplex construction in the near future.
