Description & Usage Notes
The Kemsley Yellow is produced using the extruded wirecut method, giving precise dimensions and a smooth, consistent finish. Its pale yellow colouring brings a fresh, modern feel to masonry and pairs well with a variety of materials, from traditional roof tiles to contemporary cladding.
With an F2 frost-resistance grade and a compressive strength of ? 50 N/mm², this brick is well suited for standard UK exposure conditions. Its ? 10% water absorption ensures controlled performance, but correct detailing — including cavity design, flashings, and good drainage — remains essential for long-term durability.
To achieve a consistent façade, always blend bricks from at least three packs during installation. Viewing samples before committing to a full order is advisable to confirm colour and finish.
FAQs
Is a water absorption of ? 10% suitable for external walls?
Yes — ? 10% is within the ideal range for facing bricks. When combined with proper detailing, it ensures reliable long-term performance.
What does the F2 durability rating mean?
It means the brick is frost-resistant and suitable for typical UK external exposure. For harsher conditions, such as coastal zones or heavy freeze-thaw cycles, higher-rated durability bricks may be more appropriate.
Will the yellow colour vary between packs?
Yes — natural shade variation is expected in clay bricks, especially lighter tones. Mixing bricks from several packs during laying helps achieve a more uniform finish.
