CFS/K-150 - Extra Heavy Duty Load Bearing Cavity Wall Lintel

CFS/K-150 - Extra Heavy Duty Load Bearing Cavity Wall Lintel

The CFS/K-150 lintel is intended for extremely heavy load bearing over gaps in cavity walls which have a cavity width between 150mm to 165mm. This lintel has an outer leaf width of 95mm and can support bricks with a maximum width of 102mm (95mm leaf width + 7mm overhang). The inner leaf has a width of 100mm and can support blocks of the same width.

These heavy-duty load bearing lintels are available in 150mm increments starting from 750mm up to 4800mm, allowing for load bearing over a wide variety of gap sizes.
Please note: The lintel width will need to include a 150mm minimum end bearing at each end of the lintel. For example: if the gap that needs to be bridged is 1800mm in length, then the lintel will need to have 300mm added to its length.

This range of heavy duty 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 bear the loads which are specified in the table 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 figures have been acquired through testing in accordance with the requirements of standards BS 5977 Part 2: 1983 and BS EN 845-2:2003
