Wienerberger Charthurst Red Multi Facing Brick
The Wienerberger Charthurst Red Multi is a soft mud stock-facing brick with a warm red and multi-tone finish. Its textured surface and natural variation give a traditional look, making it a popular choice for both heritage and modern builds. As with all clay products, shade variation is normal, so mixing bricks from at least three different packs is recommended for a balanced appearance.
This brick combines rustic character with dependable technical performance. With frost resistance, moderate compressive strength, and higher water absorption typical of soft mud bricks, it performs reliably in standard UK exposure when installed with correct detailing.

Description & Usage Notes
The Charthurst Red Multi is produced using the pressed soft mud process, which gives it a lightly textured, handmade appearance. Its red and multi-shade colouring provides depth and variety, making it suitable for projects that need character and individuality.
With water absorption up to 18% and compressive strength of ? 21 N/mm², this brick is tailored for facing use rather than heavy structural loads. Its F2 durability ensures frost resistance under typical UK conditions, provided good detailing — including cavity wall design, drainage, flashings, and suitable mortar — is applied.
Always blend bricks from multiple packs to achieve a consistent façade. Viewing a sample or constructing a small trial panel is recommended before committing to a full order.
FAQs
Is ? 18% water absorption too high for external walls?
Not for soft mud stock bricks — higher absorption is typical. With correct detailing and cavity design, performance is reliable.
What does the F2 durability rating mean?
It means the brick is frost-resistant and suitable for general UK exposure conditions. For extreme weather or marine environments, a higher durability brick may be preferred.
Will the colour vary between packs?
Yes — soft mud bricks naturally show variation. Mixing bricks from at least three packs during laying helps achieve a balanced and consistent finish.
