PRESS RELEASE issued 2nd March 2010
Tradical® Hemcrete® the innovative lime and hemp based renewable and highly thermally efficient alternative to conventional masonry cavity walls, has achieved British Board of Agrément (BBA) approval. With approval from the UK’s major authority on construction products, specifiers of Tradical® Hemcrete®can have total confidence in the product’s performance.
Developed in Europe by Lhoist and manufactured and distributed in the UK by Lime Technology, Tradical® Hemcrete®is produced from UK sourced hemp and a lime based binder (Tradical® HB). The product is carbon negative, as the hemp absorbs Carbon Dioxide during its growth – and as such has 130kg less embodied CO2/m² than typical conventional brick and block in a normal wall section.
Alongside its environmentally beneficial production, Tradical® Hemcrete®offers superb insulation properties. The low U-value of walls built with the renewable system make it an ideal material for meeting the higher levels of the Code for Sustainable Homes.
Homes built with Tradical® Hemcrete®, also have excellent thermal inertia, meaning that they buffer temperature variations efficiently. This ensures heating or cooling needs are lower than in lighter weight buildings of the same U-value.
Highly vapour permeable and used in conjunction with lime based renders and plasters, it ensures a healthy internal environment. Tradical® Hemcrete® also has high fire resistance, making it a safe choice for any construction.
The accreditation comes as part of Lime Technology’s commitment to provide designers with the ability to specify a lime based, BBA approved, building solution for the construction industry that they can have complete confidence in.
“With BBA accreditation, our clients are now fully assured that Tradical® Hemcrete® has been rigorously and independently assessed for its performance as a walling system for use in all building types,” said Mike Eberlin, Managing Director of Lime Technology. He added, “It’s another step towards ensuring Tradical® Hemcrete® is seen as a commercially viable material for the mainstream construction market.”
The developer of Tradical® Hemcrete®, Lhoist, is the world’s leading industrial lime manufacturer. First formulated in France, Lhoist brought the technology to the UK in conjunction with Lime Technology with a view to providing this sustainable technology to the mainstream construction market. BBA accreditation was seen as an essential part of the process and Lhoist UK has worked with Lime Technology to provide the required assessment information to BBA that has resulted in the successful awarding of the Agrément Certificate.
BBA accreditation is highly trusted by construction professionals as providing a rigorous, independent assessment of construction materials and systems. This initial certification is the first of its kind awarded to a hemp lime construction system anywhere in the world.
Francois Bardout, Vice President & General Manager Lhoist UK, commented. “We are delighted by the award of this BBA accreditation because this paves the way for this highly sustainable construction system to be adopted more readily by designers and clients as part of their environmental strategy to help tackle climate change.”
The presentation of the BBA certificate was made at Ecobuild, the world’s largest eco-construction exhibition event, on 2nd March 2010, by Greg Cooper the Chief Executive of BBA.
