Insulation for a better tomorrow


 Approved Document L 2013

15 January 2014

The new Approved Documents L1A and L2A are now available to download from the Planning Portal website. The new documents are effective from 6th April 2014 and see only a modest improvement over current standards with a 6% reduction in carbon dioxide emissions for dwellings and 9% reduction for all other buildings. Perhaps the biggest change for dwellings is the introduction of a Fabric Energy Efficiency Standard which emphasises the importance of a fabric first approach.
