After what seems like an eternity we now know the compliance criteria for windows and doors from October thanks to the publication of the 2010 approved document part L.
What does this tell us?
Firstly it would appear that the WER scheme is written in to a C rating, while not labelled the BFRC scheme, in essence that is what it is, and secondly that a draconian 1.6 U-value can be used as an alternative.
This now means that all the self-certification bodies can produce their own WER schemes, so the next round of self publicizing scammery sets in motion. With the consumer already being conned by the poor science behind the BFRC scheme, are they next to be subjected to the marketing of schemes, to ensure that they will choose a contractor using the ‘best’ scheme.
The Glass and Glazing Federation (GGF) is extremely pleased to note from the final Approved Document L (Conservation of Fuel and Power) and Approved Document F (Ventilation) for England and Wales, announced on 30 April 2010, that the Communities and Local Government (CLG) have listened to the representations of the Federation and the industry.
The principal changes announced were as follows:
For replacement windows, compliance to be based on Window Energy Rating Band C (currently Band E) with an alternative of a U Value of not worse than 1.6 W/m2K (currently 2.0). The centre pane alternative of 1.2 remains but for a limited range of applications only.
