Pilkington Welcomes New Part L Proposals
Pilkington has welcomed the Government's latest proposed revisions to Part L of the Building Regulations, especially the introduction of Window Energy Ratings (WERs).
Pilkington bulletin provides guidance on hot topic
The Pilkington bulletin provides a comprehensive introduction to the latest Window Energy Ratings.
The Approved Document will be welcomed by those who wish to see a continuation of current window specification and practice.
For PVC-U and timber replacement windows, the current U value of 2.0 continues to be acceptable, whereas the adoption of Window Energy Ratings (WERs) is a positive move.
A replacement window achieving band E is acceptable, although extensions are required to reach a slightly higher standard, where a band D window is specified.
For new buildings, designers and builders will achieve compliance by calculating the total carbon emissions of the proposed building.
There will be considerable freedom in the specification of individual components as long as the overall emissions target is met.
Current popular glazing specifications will therefore continue to be satisfactory and windows containing Pilkington K Glass will enable buildings to meet the anticipated target.
Irrespective of the target, no window in a new dwelling will be anticipated target.
Irrespective of the target, no window in a new dwelling will be allowed to have a U value greater than 2.2, which means that non low E double glazing will become a thing of the past.
Rick Wilberforce, market development manager - Europe, at Pilkington comments: "Low E glass will, in effect, be obligatory for all new build and replacement windows at a level that can be fulfilled by hard coat products such as Pilkington K Glass for at least 5 years".
For many in the industry it will be 'carry on as normal'.
