The S/K-90 WOL lintel is suitable for bearing standard loads for cavity walls with a cavity width between 90mm and 105mm. With an outer leaf width of 120mm, this lintel is suitable for outer wall blockwork or stonework with a maximum width of 150mm, a much wider profile than standard brickwork. The inner leaf has a width of 100mm, which is able to support blockwork of the same width.
This range of lintels is available in 150mm increments starting at 750mm up to 3600mm, this allows for standard load bearing over a wide variety of openings for applications such as windows or doors.
Please note: This range of lintels requires a 150mm end bearing at each end of the lintel. For example: if the opening is 1200mm in length, the required lintel will need an additional 300mm added to the length in order 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
