The S/K-150 WOL (Wide Outer Leaf) standard load cavity wall lintel is suitable for cavity widths of 150 – 165mm. With its wider outer leaf, it is ideal for use on stonework / block work outer walls which usually have a wider width than standard brickwork. The outer leaf is 120mm wide and can support a load with an overhang of an extra 30mm.
The S/K-150 WOL lintels are available in 150mm increments from 750mm up to 3600 mm to support your walls over a variety of window or door gap sizes.
Please note: The lintels width must ensure a 150mm minimum end bearing at each end, for example if there is a gap of 1800mm, you would need to add at least 300mm to the length of the lintel required.
This lintel has been constructed from high quality pre-galvanised mild steel and satisfy the thermal performance requirements of England and Wales’ Part L of the building regulations, Northern Ireland’s Part F and Scotland’s technical Handbook, section 6.
In order for the lintel to achieve the loading figures in the table below, the lintel must be installed correctly, please see the installation guide for more information.
The figures also take into account the different loading types which are common in traditional cavity wall construction. These figures have been acquired through testing in accordance with the requirements of standards BS 5977 Part 2: 1983 and BS EN 845-2:2003
Differential Total UDL kN 3:1 (up to 75% loading on the inner leaf)
Differential Total UDL kN 19:1 (up to 95% loading on the inner leaf)
