The Calderstone Russet facing brick from Ibstock delivers a rich, deep red / russet hue with natural variation that gives facades warmth, depth, and character.

This makes it an ideal choice for projects seeking durability without compromising on visual interest. Whether you're constructing new builds, extensions, or doing sympathetic renovations, Calderstone Russet blends classic appeal with the performance specification needed for external UK conditions. The brick’s strength, stability, and exposure resilience make it a compelling option for architects and builders alike who demand both substance and style.

Frequently Asked Questions
Is Calderstone Russet suitable for exposed or coastal environments?
Yes — with its **F2 durability rating** and relatively low absorption, it is engineered for external exposure. In harsher or coastal sites, ensure sound detailing (good cavity design, flashings, weep holes, and proper mortar) to maintain long-term performance.
How variable is the red / russet tone across bricks?
Because it’s a **multi-tone product**, you will see shifts in red, russet, and related accent hues. To achieve a more balanced façade and avoid banding, it’s best to **mix bricks from several packs** during installation.
Does the ? 9 % water absorption present a good barrier to damp over time?
Yes — a **9 %** absorption value is quite favorable for a facing brick. Still, the best protection against moisture comes from how the wall is built — correct cavities, flashing, drainage, and compatible mortar all play more critical roles than absorption alone.
