PGH Bricks
Bricks are a classic and enduring building material. Take a look around your neighbourhood, and you'll likely notice homes showcasing bricks in a variety of colors, textures, and designs. This time-honoured material remains a top choice for homeowners across New Zealand, valued for its durability and versatility. But have you ever wondered what goes into creating a brick?
Let’s explore some of the most common questions about bricks to help you appreciate their versatility and potential for your next project.
How are bricks made?
Bricks are typically manufactured using one of two methods: extrusion or dry pressing. At PGH Bricks, the extrusion method is used across all production sites. This technique is responsible for the creation of popular profiles, including newer options like Driftwood Grey and Eclipse.
Extruded bricks
Extrusion involves pushing clay through a die to shape it, which creates the characteristic holes in many bricks. These holes serve several purposes: they make the bricks lighter, facilitate the drying and firing process, and improve handling for bricklayers.
Extruded bricks offer a wide range of textures and finishes. Techniques such as wire cutting or applying surface coatings result in textures that range from smooth to rugged. These textures also make extruded bricks versatile, allowing finishes like paint or cement render to adhere effectively.
How are bricks coated?
Some bricks receive a coating or glaze during the extrusion process. These coatings, which are kiln-fired onto the brick’s surface, can provide finishes ranging from matte to glossy. Additionally, they enhance the texture, from smooth and polished to coarse and rustic, offering numerous aesthetic options for builders and homeowners alike.
What’s the difference between solid and extruded bricks?
Extruded Bricks: Often called “bricks with holes,” extruded bricks are designed with voids to reduce weight and ensure uniform firing. They are easier to handle and ideal for general construction purposes.
Solid Bricks: These bricks are manufactured without holes, making them heavier and more robust. Solid bricks are commonly used in applications like windowsills or door openings to ensure a seamless appearance. They’re also favoured for projects requiring high thermal mass, such as passive solar designs, and for structural applications like retaining walls.
What are colour-through bricks
Colour-through bricks feature consistent pigmentation throughout the entire brick. This means that if the surface is scratched or chipped, the colour underneath matches the face. An excellent example is the PGH Gypsy Rose, a brick with rich red and brown tones that add warmth and character to any design.
Why choose brick for your next project
Bricks offer unparalleled flexibility in design, durability, and energy efficiency. From creating striking exteriors to enhancing interior spaces, bricks provide a timeless foundation for any build.
