The Joinery Network co-operative has launched the Lignum, said to be the UK’s first timber window and door system that fully complies with Building Regulations, with full PAS 24:2016, Document Q, BS 6375: 1, Document L1B, and Document M certification.

The Lignum range includes flush casement, box sash and spring balance vertical sliding windows, along with French, single, entrance and bifold doors.

“Timber windows and doors have become one of the fastest growing home improvement and construction products post-lockdown,” said co-founder Owen Dare. “Windows are no longer a distress purchase – instead, homeowners choose to improve their homes with new windows that add style and character and meet demands for more sustainable products. Timber is the ideal choice for this, and we believe Lignum by The Joinery Network is the golden ticket for glazing installers.”
