Its light texture ensures a refined surface that diffuses light gently and softens mortar contrast. Because it belongs to the London Brick family, it’s often chosen for extensions or renovations where matching existing brickwork is important.\n\nThe brick is manufactured via a pressed process with a light texture, giving consistent form and crisp edges while maintaining subtle character. As a facing brick, it’s designed to be the visible external layer of wall construction, combining aesthetic appeal with structural performance.\n\nIn terms of performance, Nene Valley Stone carries a durability rating of F1, a water absorption rate of 23 %, and a compressive strength of 25 N\/mm². Its standard size is 215 × 102.5 × 65 mm, and it’s frogged with 15–20 % voids. When installed with proper detailing (cavities, flashing, weep holes, good mortar), it offers dependable resilience in UK external conditions.\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSize:\u003c\/b\u003e215 × 102.5 × 65 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eColour:\u003c\/b\u003eBuff \/ Stone tones\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTexture:\u003c\/b\u003eLight\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWater Absorption:\u003c\/b\u003e? 23 %\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDurability:\u003c\/b\u003eF1 (suitable for general external exposure)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003eIs Nene Valley Stone London suitable for coastal or highly exposed areas?\u003c\/h4\u003e Yes — its **F1 durability rating** means it can be used in external settings. In more challenging environments, it's especially important to ensure excellent detailing: good flashing, reliable cavity design, proper mortar, and correct drainage to maintain long-term performance. \u003ch4\u003eHow noticeable will the buff tone variation be across a wall?\u003c\/h4\u003e You’ll see gentle shifts in buff and stone tones across bricks — part of the natural clay effect. To avoid visual banding or patches, it’s best practice to **mix bricks from multiple packs** during installation so the variation is spread evenly across the wall. \u003ch4\u003eDoes the 23 % absorption rate risk damp over time?\u003c\/h4\u003e A water absorption of **? 23 %** is typical for many London Brick products. The real defence against moisture is high-quality installation — proper cavity, flashing, weep holes, and good mortar matter much more than the absorption number alone.\u003cbr\u003e\u003cp\u003eCheck out our full range of \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/building-supplies\"\u003ebuilding supplies\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eBrowse more \u003ca href=\"https:\/\/jjbuildingmaterials.co.uk\/collections\/bricks-blocks\"\u003ebricks \u0026amp; blocks\u003c\/a\u003e available online.\u003c\/p\u003e","brand":"Forterra","offers":[{"title":"Default Title","offer_id":51448210358614,"sku":"161758","price":611.3,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/4509\/4998\/files\/forterra-lbc-nene-valley-stone-facing-brick-pack-of-390-2857788.jpg?v=1772657116","url":"https:\/\/jjbuildingmaterials.co.uk\/products\/forterra-lbc-nene-valley-stone-facing-brick-pack-of-390","provider":"JJ Building Materials","version":"1.0","type":"link"}
