NHBC Standards identify acceptable weathering materials for 2016

Midland Lead has addressed the construction industry’s misunderstanding concerning the 2016 NHBC Standards and acceptable forms of weathering materials.

Since the publication of the 2016 NHBC Standards for the house building industry, there has been some confusion among construction professionals regarding the acceptability of certain forms of weathering materials.

Many have suggested that the updated edition instructs housebuilders to use BSEN12588 Rolled Lead Sheet in any new home registered with NHBC.

However, the new Standards do not limit housebuilders to this extent; they recognise a range of appropriate materials for flashings. Midland Lead’s machine cast lead, for example, is acceptable under trademarked products.

NHBC Standards 2016: clearing up confusion

As the lead is manufactured through a machine casting process, as opposed to a milling one, it cannot qualify for BSEN12588. However, as it boasts BBA certification, it holds the valid third party technical accreditation that NHBC requires.

The 2016 edition of the Standards will offer technical information in a user-friendly format. A new chapter on re-occurring basement issues has also been included.

As production levels continue to increase across the UK, the Standards aim to offer support to the industry in delivering high quality new homes.

They will become effective for every new home registered with NHBC where foundations begin on or after 1 January 2016.
