Hanson's latest green addition to its extensive masonry range is the Oast House Red Multi brick. It is another example of the company's careful attention to the energy-efficient production of high quality masonry products. As the UK's largest brick manufacturer and a founder member of the UK Green Building Council, Hanson is leading the industry with its commitment to sustainable production methods. The Oast House Red Multi is a vibrant, red-body brick with brown flashing which contains a small percentage of black sand accents to bring variation to its face.
