Clumber Red Mixture – Butterley / Forterra Facing Brick
The Clumber Red Mixture facing brick is part of Forterra’s Butterley line — a visually rich, mixed red-tone brick that brings texture and depth to external walls and feature facades. With its warm multi-blend of reds, browns, and occasional accent hues, it delivers a dynamic look that works beautifully in both traditional and modern architectural settings. Whether you're building a full elevation, an extension, or a detailed accent wall, Clumber Red Mixture adds natural variation and character.
Produced using a wirecut process and finished with a light texture, this brick strikes a balance between refined surface and tactile interest. It avoids being overly rough while still capturing shadow and variation across each face. The mix of tones helps soften contrast between bricks and mortar, giving walls a more organic, less regimented appearance.
On the performance side, Clumber Red Mixture is engineered to last. It carries a durability rating of F2, making it suitable for exposed external use across typical UK climates. Its water absorption is rated at 15 %, which is common among facing bricks. When combined with correct detailing — such as appropriate cavity design, flashing, drainage, and quality mortar — it offers reliable protection against weathering, moisture, and freeze-thaw cycles.

Frequently Asked Questions
Can Clumber Red Mixture be used in coastal or highly exposed areas?
Yes — with its **F2 durability rating**, it is designed for exposed external applications. In more aggressive environments, careful detailing (e.g. cavity design, flashing, weep holes) becomes even more important to maintain long-term performance.
How much colour variation should I expect with this “mixture” brick?
As a mixture brick, variation is part of the design. Expect shifts in red and brown tones throughout the batches. To avoid visual clustering, it’s best practice to **blend bricks from multiple packs** while laying so the variation spreads evenly across the façade.
Does 15 % water absorption pose a risk of damp over time?
Not necessarily — **? 15 %** is a typical value for many facing bricks. Moisture performance depends more on installation quality (correct cavity, flashing, drainage, mortar) than on the absorption number alone. If detailed properly, the brick should handle moisture well over time.
