Part L 2013

The direction of improving carbon and energy reduction in buildings is well known and Part L of the building regulations in England is one of the tools used by the government to achieve these objectives. The 2013 changes came into force on 6th April 2014 and the main headlines can be found by clicking here.

We are very active in supporting the glass trade by responding with practical suggestions that allow designers of buildings to use glass extensively in buildings.  It is important that the energy saving qualities of glass are properly represented in Part L as well as keeping windows practical and affordable. We see the role of glass as a major contributor towards the objectives by encouraging the most efficient products in new homes and the replacement of poorly performing windows in existing homes and extensions. 

Hand in hand with Part L are the compliance tools such as SAP and SBEM.  Although the tools contain default values for windows they do tend to be very conservative. We would encourage all designers to use manufacturers' values in these programs and real window sizes and orientations to realise the contribution that energy efficient windows can make.  Our Spectrum online calculator can be used to quickly determine the g value and centre pane U value for our range of thermal insulation and solar control glass.
