The S/K-90 WIL standard load bearing cavity wall lintel has been designed to bear loads for cavity walls with a width between 90mm to 105mm. This lintel has a 125mm wide inner leaf which is suitable for blockwork with a maximum width of 150mm. The outer leaf of the lintel is 95mm wide which will be suitable for standard brickwork.
The S/K-90 WIL range of lintels are available in 150mm increments starting at 750mm up to 4200mm, which allows for load bearing over a wide range of opening lengths for various applications such as for doors or windows.
Please note: To install the lintel correctly, a 150mm end bearing is required at each end of the lintel. For example if the length of the opening that needs to be bridged is 1200mm, then the lintel length will require an additional 300mm added to its length to accommodate the end bearings.
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 this lintel to support the specified loads below, the lintel will need to be installed correctly.
The figures also take into account the different loading types which are common in traditional cavity wall construction. These lintels have been tested as a composite unit with surrounding masonry and have been built in accordance with BS EN 1996-2:2006. 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)
Should you require a wide inner leaf lintel which can bear a heavier load, we also provide the HD/K-90 WIL heavy duty load bearing cavity wall lintel.
