Double Brick is the most common method of construction in WA.
Construction consists of two layers(sometimes called leaves) of masonry with a cavity between them. The layers are connected by steel ties at regular intervals.
As this form of construction can also use limestone, rendered brick and concrete block for the external face, and brick or concrete block for the internal leaf, a better description would be Structural Masonry, Cavity Construction.
The purpose of the cavity between the outside layer of brick and the inside layer so that moisture doesn’t penetrate into the home. In more sustainable homes this cavity is partially or fully filled with insulation.
Internal walls are usually a single brick thickness and generally use a 2nds brick or concrete block that is plastered or lined using a lining board.
- It is extremely durable requiring very little maintenance.
- The mass of the brickwork can help moderate the internal temperature of the dwelling
- You can place a heavy fixing anywhere on the walls.
- More expensive than Brick Veneer.
- Not as well insulated.
- The house will take a long time to warm up in winter or cool down once it does get hot.
- Likely to crack if subjected to ground movement.
