Things to check before you order

Do I need a cavity tray?

Over openings in cavity walls, water in the cavity has to be directed outwards. Many steel lintels need a separate cavity tray and stop ends; check the lintel maker's detail.

Steel or concrete?

Steel cavity lintels support both leaves and include insulation to limit cold bridging. Concrete lintels are simple and robust for single leaves and internal walls.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Working out quantities for your Welwyn Garden City job

For a 1,800 mm clear opening, add at least 150 mm of bearing at each end: the lintel needs to be at least 2,100 mm long. Then pick the type for the wall build-up and check the load in the manufacturer's table, or ask your engineer if the opening carries a floor or roof.
