When it comes to choosing the right material for a home’s construction, there are several options available. Clients want to know which material will work best for them and that is also something you will learn during a bricklayer’s apprenticeship.

Two of the most popular materials used in Australia are brick veneer and double brick. Both have their advantages and disadvantages, and it’s essential to understand the differences between them before making a decision.

What Is The Difference Between Brick Veneer And Double Brick?

There are several differences between the brick veneer and double brick and this information from the experts at Brick & Block Careers will help you determine which one is right for a project.

What Is Brick Veneer?

Brick veneer is a type of construction that consists of a single layer of bricks that are placed against a timber or steel frame. The frame supports the weight of the roof and upper floors, while the brick layer is attached to the frame using wall ties. The gap between the brick layer and frame is filled with insulation material to improve the thermal performance of the wall.

Advantages of Brick Veneer

  • Cost-Effective – Brick veneer is generally less expensive than double brick, as it requires fewer materials and less labour to construct.
  • Energy Efficient – Brick veneer walls are energy-efficient due to the gap between the brick layer and frame, which is filled with insulation material. This helps to keep your home warm in winter and cool in summer.
  • Lightweight – Brick veneer is a lightweight construction material, which means it places less stress on the foundation of your home. This can be particularly beneficial in areas with expansive soils or unstable ground conditions.

Disadvantages of Brick Veneer

  • Lack of Sound Insulation-Brick veneer is not as effective at reducing sound transmission as a double brick. This means that noise from outside your home can be more easily heard inside.
  • Limited Durability-Brick veneer is not as durable as double brick, as it is susceptible to moisture damage and cracking.

What Is Double Brick?

Double brick is a type of construction that consists of two layers of bricks that are placed one on top of the other, with a cavity between them. The cavity is typically filled with insulation material to improve the thermal performance of the wall. Double brick construction is a popular choice for residential and commercial buildings in Australia due to its durability and fire-resistant properties.

Advantages of Double Brick

  • Sound Insulation – Double brick construction is highly effective at reducing sound transmission, making it an excellent choice for homes located in noisy areas. The double layer of bricks creates a barrier that helps to block out external noise, providing a quieter and more peaceful indoor environment.
  • Durability – Double brick construction is highly durable and can withstand a range of weather conditions. The two layers of bricks create a strong and sturdy structure that is less susceptible to damage from moisture, cracking or other forms of wear and tear. This makes double brick a good long-term investment for homeowners, as it can provide reliable protection against weather and other external factors.
  • Fire Resistance – Double brick is highly fire-resistant, making it an excellent choice for buildings located in bushfire-prone areas. The two layers of bricks act as a barrier that can help to prevent the spread of fire, providing an added layer of safety for occupants.

Disadvantages of Double Brick

  • Cost – Double brick construction is generally more expensive than other forms of construction, such as brick veneer or timber framing. This is due to the additional materials and labour required to construct the double brick walls, which can add to the overall cost of the project.
  • Heavy – Double brick is a heavy construction material, which means it places more stress on the foundation of your home. This can be a concern in areas with unstable ground conditions, as the weight of the walls can cause the foundation to shift or sink over time. This can lead to structural issues, such as cracks in the walls or floors, that may require costly repairs.

How to Check If Your Property Is Brick Veneer or Double Brick

To determine whether your property is brick veneer or double brick, you may use the following methods:

Examine the exterior

  • Brick Veneer: Check for a noticeable gap between the bricks and the internal walls. In brick veneer construction, there is a space between the brick outside and inner walls.
  • Double Brick: If the outside and interior walls appear to be solid brick with no visible gaps, the structure is most likely double brick.

Measure the wall thickness

  • Brick Veneer: Determine the thickness of an outside wall. Generally, brick veneer walls are thinner than double brick walls.
  • Double Brick: If the walls are especially thick, this may indicate double brick construction.

Check the windows and doors

  • Brick Veneer: Examine the window and door frames. In brick veneer construction, these are frequently installed in the wall and may have a noticeable gap between the frame and the brick.
  • Double Brick: In double brick construction, the frames are typically inserted straight into the brick, with no visible gap.

Check out the construction plans

  • Brick Veneer: If you have access to the original construction blueprints, they should indicate whether the property is brick veneer or double-brick.
  • Double Brick: Similarly, the drawings will indicate whether the property is built with double bricks.

Tap the wall

  • Brick Veneer: If you tap on the external walls and hear a hollow sound, it is most likely brick veneer.
  • Double Brick: Tapping on the walls produces a substantial sound, indicating double brick construction.

Consult a professional

If you’re still unsure, try contacting a professional inspector or structural engineer to check your property’s construction. They can provide a more accurate judgement based on their experience and may use tools such as borescopes to investigate wall cavities.

Brick Veneer Or Double Brick?

During your bricklayers’ apprenticeship, you will learn more about things like the difference between the brick veneer and double brick. The choice between the brick veneer and double brick for a building project depends on a variety of factors such as budget, location, personal preferences, and design requirements. Brick veneer is a more cost-effective option that can still provide excellent thermal performance and sound insulation.

Double brick, on the other hand, offers superior durability, fire resistance, and sound insulation, but at a higher cost. It is important to weigh the pros and cons of each option and determine the best choice for your specific project needs.

If you want to become a professional bricklayer, you need to have a sound foundation and that is where we come in.
