Wine Society's warehouse uses preformed panels of hemp and lime that locks in carbon dioxide
The UK's first warehouse building to be constructed using preformed wall panels made out of hemp has now been completed.
The £3.7m warehouse for the Wine Society in Stevenage, Hertfordshire, has been designed by architect Vincent & Gorbing and has exterior walls built of Tradical Hemcrete, which is a mixture of hemp stalk and modified lime. It is a development of cast insitu hemp-lime walling that locks carbon dioxide within the wall construction.
Mark Chandler, architect and director of Vincent & Gorbing, said: “The design responds to the requirement for minimal heating and cooling equipment with the resultant reduction in energy consumption.”
The cladding offers good insulation properties, explains Chandler, and helps maintain a stable internal air temperature throughout the summer and winter.
The 8.5m2 panels, which are 300mm thick, are mounted on the building's steel truss frame, while a 40mm-thick composite aluminium panel is used to provide weather protection on the external face.
Together with the highly insulated roofing system, it provides an insulated internal space that exceeds Building Regulations requirements.
