FAQ

What are bricks made from?

Bricks are composed of clay and shale. The colour of bricks depends on the clay mix used, firing temperatures, kiln car setting and additives. Additives might include sawdust, coal, coke and manganese.

 

How many bricks are there in a square metre?

For a standard brick which is 230mm x 76mm there are 48.5 bricks per square metre (which includes the mortar joint).

 

What is an Exposure Grade Brick?

Bricks that can become exposed to a severe marine or saline environment need to be exposure grade. Exposure Grade bricks are less susceptible to salt attack. In accordance with the Building Code of Australia, Exposure Grade bricks must be used where the construction is within 1km of a surf coast or 100m of a non-surf coast.

 

Do bricks improve energy efficiency?

Brick is a natural insulator. Its ability to absorb and release thermal energy (heat or ‘cool’) over an extended period makes it an ideal choice for reducing the amount of energy used for mechanical heating and cooling and therefore reducing carbon emissions. When used with passive solar design principles, brick has helped achieve an 8 star energy rating on residential houses.

 

Should Hydrochloric Acid be used to clean bricks?

Acid cleaning using hydrochloric acid (HCl) should normally only be used to remove mortar stains. Generally, hydrochloric acid should not be used to treat any other stains or at any other time during the life of your bricks. If used incorrectly, it can cause unsightly staining that is more difficult to remove. For more information view the Think Brick Cleaning Manual. 

Fire Resistance  

What does it mean?

 

Fire resistance levels are specified in the Building Code of Australia (BCA). This system provides an accurate method of predicting the ability of a wall to maintain its strength in a fire and to resist the spread of the fire. The fire resistance level (FRL) specifies the fire resistance periods (FRP) for structural adequacy, integrity and insulation. These components can be defined as:


Structural Adequacy - The ability of a wall to continue to perform it’s structural function.


Integrity - The ability of a wall to maintain its continuity and prevent the passage of flames and hot gases through cracks in the wall.


Insulation - The ability of a wall to provide sufficient insulation, such that the side of the wall away from the fire does not exceed a predefined rise in temperature. The fire resistance level is expressed in minutes and lists the three components as:

 

i) Structural Adequacy

ii) Integrity 

iii) Insulation


For example, an FRL of 90/90/90 means a minimum fire resistance period of 90 minutes each for structural adequacy, integrity and insulation. FRL’s can be determined from Australian Standard AS 3700 (Masonry Structures) or by testing in accordance with AS 1530.4. The fire resistance level of a wall depends not only on the thickness of the wall but also on its height, length and boundary conditions (i.e. how it is connected to other building elements). The Fire Resistance Levels expressed on our website are based on test results. Contact us if you require further technical details.
