The K-BRIQ® is a resource-efficient facing brick made from inert recycled construction and demolition waste, offering an ultra-low carbon alternative to traditional masonry and architectural surfaces, with an embodied carbon less than 95% of that of a traditional clay brick (16.77g CO2e per K-Briq). It is suitable for applications currently met by traditional facing bricks and blocks, above or below DPC, in exterior and interior environments. It is available in 13 standard colours with reaction to fire ratings of A2 and B across the range; a bespoke colour and shape development service offers further design flexibility.

The K-BRIQ won both the global public vote and the final judges’ vote in the Dezeen Awards for Sustainable Design in 2022 and has had audiences with HRH King Charles, UK, Scottish and international Ministers, and many international delegations when it formed part of a striking central exhibit in the Sustainability Zone at COP28. The company is a spin-out from Heriot Watt University and has its first commercial scale production facility based outside Edinburgh. The company’s scaling and growth strategy is to set up regional production across the UK and internationally, to provide a closed loop circular solution to construction and demolition waste locally, whilst supporting local job creation, local supply chains – and be a key contributor to driving down embodied carbon on the road to net zero.

What is a digital material passport?

A material passport is a digital document listing all the materials that are included in a product or construction during its life cycle in order to facilitate circularity decisions in supply chain management at the end of the building life.

At Cundall, we want to create a passport to materials/products that will also provide information before its use so designers and contractors are capable of making conscious decisions of products that could affect the embodied carbon and health well-being of a project, facilitating the inclusion of the best low carbon and/ healthy materials that align with their design.
