A reliable timber window and door system for modern installation businesses
If you already sell timber windows and doors — or plan to introduce them in 2026 — Lignum removes the barriers that have traditionally made timber difficult to sell.
Designed for installers supplying aluminium and timber-look PVCu, Lignum gives you authentic timber with the certainty of a national network of manufacturers.
Lignum breaks the mould for installers
Timber demand is growing, but many installation businesses have held back because of long, unpredictable lead times when the joinery shop get busy.
Dependency on a single factory with limited Document Q and Part L compliant products is a common barrier to growing sales with timber windows and doors.
Lignum breaks the mould for installers with a superior, fully certified timber window and door system – manufactured across the UK by a network of specialist joinery companies.
Certainty of supply for installers
Lignum is supplied through a nationwide network of 50 UK-based System Manufacturers, collectively delivering over £30 million of superior quality timber windows and doors every year.
This multi-manufacturer model means you’re never reliant on one supplier – giving your business consistency, scalability and confidence.
