From understanding F2 frost ratings and imperial sizing to navigating textures and using specialist calculators, here is the definitive framework for specifying the right brick for your project.
Choosing a brick is arguably the most defining decision in any construction or landscaping project. It is the visible "skin" of the building, dictating both its immediate curb appeal and its long-term resilience against the British climate.
But a facing brick is more than just a coloured block of clay. It is a complex specification product balanced between aesthetics and engineering. Whether you are planning a full house build, a rear extension, or a decorative garden wall, making the right choice requires moving beyond just looking at colour charts.
This guide breaks down the essential technical specifications, style classifications, and practical tools required to select facing bricks with confidence.
The Core Distinction: What is the Difference Between a Facing Brick and an Engineering Brick?
The primary function of a facing brick is to be visible. They are designed to enhance the visual appeal of a property, offering a balance of durability, design versatility, and character.
By comparison, engineering bricks are functional workhorses. To provide a technical benchmark, a standard Class A engineering brick offers extremely high compressive strength (typically around 125 N/mm²) and very low water absorption (<4.5%).
The Critical Specifications: Sizing and Durability
To ensure longevity in exposed masonry construction, you should prioritize bricks with an F2 category rating. An F2 rating indicates that the brick has good frost resistance and is suitable for the demands of the British winter.
Frequently Asked Questions
Should I use 65mm or 73mm bricks for my project?
The choice depends on the age of your property:
- 65mm (Metric): The modern UK standard for almost all new builds since 1970.
- 73mm (Imperial): Common in older properties or heritage renovations, particularly in the Midlands and North of England.
If you are building an extension, matching the existing brick height is vital to ensure your mortar joints align.
What are the main manufacturing types of facing bricks?
There are four primary production methods, each offering a distinct finish:
- Wirecut: Extruded and cut with wires for a sharp, uniform, and contemporary look.
- Stock: Characterised by a softer, more traditional texture.
- Handmade: The most rustic option, featuring unique folds and irregularities for a premium "heritage" feel.
- Pressed: Highly dense bricks formed in a mould under high pressure for precise dimensions.
Can you match my existing bricks for an extension?
Yes. DBM DIY offers a specialist Brick Matching Service. Because bricks are natural products, colours and textures vary between batches and manufacturers. Our experts can identify the closest match from leading brands like Ibstock, Wienerberger, and Forterra to ensure your extension blends seamlessly with your original masonry.
What are special shaped bricks used for?
Special shapes (or "Specials") are used to create architectural details that standard rectangular bricks cannot achieve. Common examples include:
- Bullnose: Rounded edges for corners or window sills.
- Cant Bricks: Angled faces for creating chamfered edges.
- Plinth Bricks: Used to create a visible change in wall depth at the base of a building.
