Mastering Brick Headers and Header Rows in Construction
Have you ever realized the significance of something considered simple or even overlooked?
The humble brick header and its placement in patterns – known as header rows – stand as a prime example. Let’s discover why these are more than mere elements of a well-built brick wall and understand their different roles in construction.
In this article, we will get familiar with the definition of a brick header and its importance in maintaining the structural integrity of various construction projects. We will explore the blend of aesthetics and strength it offers while helping to retain the archaic charm of brickwork.
In addition to this, we’ll understand the concept of a header row and learn about its strategic presence in brickwork.
So let’s begin by uncovering the fundamentals and finesse behind brick headers and header rows!

Understanding the Term: Brick Header
Definition of a Brick Header
A brick header is a specific type of brick that is laid with its shortest side showing on the face of the wall. This method of laying bricks is used to create strong, interlocking structures.
Importance of Brick Headers in Construction
Brick headers play an essential role in ensuring the structural integrity and stability of a brick wall. Here’s why:
- Strength and Stability: Headers help tie the exterior and interior brick walls together.
- Load Distribution: They distribute the load more evenly, reducing pressure on any single point.
- Pattern Formation: Headers contribute to various brick-laying patterns like Flemish bond or English bond.
Common Brick-Laying Patterns Using Headers
Certain brick-laying patterns make extensive use of headers. Here are a few of the most common:
Flemish Bond
In a Flemish bond, headers and stretchers (bricks laid lengthwise) alternate in each row. This creates a visually appealing and structurally sound pattern.
English Bond
In an English bond, each row alternates entirely between headers and stretchers. This pattern is known for its high strength and less frequent use of headers.
Technical Specifications
| Specification | Details |
|---|---|
| Dimensions | Typically, bricks are 2 1/4″ x 3 3/4″ x 8″, but headers are side-on, so only the 2 1/4″ and 3 3/4″ sides show. |
| Material | Usually made from fired clay, sand, and lime. |
| Placement | Headers are placed with the shorter face visible on the exterior. |
Practical Applications
Brick headers are commonly used in:
- Load-Bearing Walls: To enhance stability.
- Decorative Walls: For interesting visual patterns.
- Arches: To create a strong and visually appealing structure.

This well-rounded understanding of brick headers will undoubtedly aid any construction project focused on both aesthetics and structural integrity.
Exploring the Features: Brick Header Row
The Idea behind a Header Row
A header row, in brick construction, distinguishes itself as the row where all the bricks are placed in a header position. This concept is not just visually distinctive but serves important purposes in brickwork.
Key Functions of a Header Row
The presence of the header row in a brick wall is not accidental but strategic. It serves several integral, functional roles like:
- Structural Integration: The header row offers significant integral strength tying together perpendicular walls or the different layers of a wall.
- Transference of Gravity Load: It efficiently transfers the weight of the wall above (gravity load) to the bricks below, ensuring better weight balance.
- Added Visual Element: The repetitive pattern created by the header rows introduces an aesthetic visual element in the overall design.
Position and Specification of a Header Row
In terms of positioning, a header row typically gets featured every sixth row in a standard brick wall. However, the frequency of header rows can vary depending on the structure’s specific needs and the architectural style followed.
Incorporation in Brickwork Patterns
In brickwork patterns, two widely appreciated styles make extensive use of header rows:
Flemish Bond
In a Flemish bond, bricks alternate between headers and stretchers. This pattern type is inherently strong and is usually employed for structural and decorative purposes.
Rat-Trap Bond
The rat-trap bond involves placing bricks vertically, making each alternate course a header course. The formation results in a hollow core that provides insulation against heat and sound.
Specifications of a Header Row
| Specification | Details |
|---|---|
| Row Frequency | Typically featured after every five course of stretchers. |
| Compression Strength | Header rows enhance the brickwork’s ability to withstand compression forces. |
| Aesthetic Appeal | Contributes to the overall visual impression of the brickwork. |
Usage Considerations
The application of brick headers and specifically header rows should be considered based on the:
- Purpose of the Wall: More header rows may be used for load-bearing walls.
- Design Intent: The desired aesthetic effect may influence the frequency of header rows.
- Material Availability: The size and type of brick available could affect the feasibility of creating header rows.
For a deeper insight into brick headers and header rows, you might find the Brick Industry Association’s notes on brick bonds quite informative. Finding the correct balance of header rows in your project can dramatically enhance both its beauty and strength.
Role of a Header Course in Brickwork
Understanding Header Courses
In brick construction, a header course refers to a row of bricks laid with their headers (short sides) facing out. This construction technique plays a vital role in various architectural and structural aspects of brickwork.
Key Indicators of Header Courses
Here’s why header courses are significant:
- Improved Bonding: Header courses are crucial for connecting two walls at right angles, improving the overall bond of the brickwork.
- Thermal Efficiency: These courses can enhance thermal mass, which improves the efficiency of temperature regulation inside the structure.
- Masonry Aesthetics: Header courses often contribute to specific aesthetic styles and patterns in mason work, such as the Basket Weave or Herringbone patterns.
Incorporation of Header Courses in Patterns
Understanding their role in different brick-laying patterns reveals their importance and utility.
English Pattern
In the English pattern, headers make up one row, then are followed by a row of stretchers. They continue alternating in this pattern for each consecutive course. This pattern is visually striking and also structurally stable.
Basket Weave Pattern
In a Basket Weave pattern, headers and stretchers are arranged in pairs at right angles to each other. This pattern mimics the appearance of woven baskets, offering a distinct and decorative finish.
Technical Specifications of Header Courses
The following table summarizes the specifics related to header courses:
| Specification | Details |
|---|---|
| Dimensions of Bricks | Typically, 2 1/4″ x 3 3/4″ x 8″ |
| Frequency | Often every 5-6 courses depending on structural needs |
| Orientation | Short side (header) facing out |
| Primary Use | Structural bonding, thermal regulation, aesthetic patterns |
Practical Takeaways
When working with header courses, consider the following:
- Wall Type: For load-bearing and exterior walls, more frequent header courses can enhance strength and stability.
- Thermal Regulation: Properly placed header courses can aid in maintaining consistent internal temperatures.
- Material Considerations: The type, size, and shape of the bricks available can influence the design and effectiveness of header courses in your project.
Understanding Brick Headers: Concluding Remarks
The role of brick headers and header rows in construction cannot be overstated. They contribute significantly to the strength, stability, and aesthetic appeal of brick structures.
Headers, when laid side-on, tie together exterior and interior brick walls, distribute load evenly, and give rise to various brick-laying patterns like Flemish and English bonds.
Header rows, characterized by bricks placed in a header position, are implemented strategically to bolster structural integration, facilitate the transference of gravity load, and add an artistic touch to brickwork. Different brickwork patterns such as a stack bond or rat-trap bond exhibit extensive utilization of header rows.
Finally, a header course, a row of bricks laid with their short sides facing out, enhances bond amongst brickwork, promotes thermal efficiency, and aids in achieving delightful masonry aesthetics. Knowledge of these brick construction essentials can greatly enhance the outcome of your next building project.
