Structural

Details of the structural components that appear in most residential drawings. This category includes steel lintels for timber frame, standard and pre-stressed concrete lintels, cavity wall lintels in a range of sizes, thermally broken cavity wall lintels, extreme load lintels, and precast concrete slip sills and stooled sills, plain and chamfered.

Why use a thermally broken lintel? A thermal break between the inner and outer parts of the lintel reduces heat loss at the window or door head, which helps with Part L and lowers the risk of condensation.

Do I still need a structural engineer? Yes. Lintel size and type depend on the span and load, so confirm them with the manufacturer’s tables or an engineer.
