S/K-150 WIL - Standard Load Cavity Wall Lintel - Wide Inner Leaf

S/K-150 WIL - Standard Load Cavity Wall Lintel - Wide Inner Leaf

This wide inner leaf lintel, S/K-150 WIL is suitable for cavity widths between 150mm and 165mm. The S/K-150 standard load lintel has a 95mm outer leaf and a 125mm inner leaf. With its wider inner leaf, this lintel is ideal for supporting blockwork or stonework which may have a wider profile than standard brickwork. The S/K-150 can support blocks or stonework on its inner leaf with a maximum overhang of 25mm for a maximum width of 150mm

Available in 150mm increments starting from 750mm up to 3600mm, allowing for load support over a wide variety of gap sizes for applications such as for windows or for doors.
Please note: The width of the lintel will need to allow for a 150mm minimum end bearing at each end of the lintel. For example if the gap is 1800mm then an additional 300mm is required on the length of the lintel.

This range of standard load bearing lintels has been made 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 that have been listed 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)
