In 2012 Lignacite Ltd committed to a ‘Sustainable Strategy for Masonry’. This initiative has been the catalyst to enable us to respond to the construction industry’s need for industry-wide reporting of sustainability performance as well as delivering on our commitment for continuous improvement. 2017 continues to see Lignacite striving for improved manufacturing processes and products.

All Lignacite’s blocks contain recycled materials, one is consistently chosen for its sustainable credentials – ‘Lignacite’.

The ‘Lignacite’ block, with key benefits for the build process including high fire resistance, excellent sound insulation, good thermal performance, a range of face finishes and with a recycled content of up to 48% has continued to reinvent itself over the years.  The wood was first used because it was plentiful and there was a general shortage of building blocks just after the war.  It transpired that this material not only produced a lighter block than conventional concrete, but that it made for lighter, smoother block.

Conventional concrete made with stone ultimately shatters under intense heat.  The wood in Lignacite is locked up in the matrix of the block thus denying oxygen to the flames.  This means a Lignacite blocks calcifies and hardens in a fire, giving a superior fire rating and performance.

The fact wood locks up C02 due to photosynthesis has meant more recently its environmental credentials have been even more widely recognised, thus adding benefits to projects using Lignacite blocks.

The Architects of some of the country’s most iconic buildings made have this choice.
