Where to use a Catnic CH150/100 lintel
The CH150/100 is designed for heavy duty masonry cavity-wall construction with a 150–165mm cavity. It supports specified masonry, timber floor and roof loads where the selected lintel's rated capacity is sufficient.
Its open-back profile allows masonry to be built continuously on both leaves and is suitable for fair-faced inner leaf masonry.
Choosing the correct CH150/100 length
Catnic's published loading figures use nominal 150mm end bearings at each end. As a general starting point, add 300mm to the clear structural opening width to allow for these bearings.
For example, a 1200mm structural opening would normally require a 1500mm lintel, with 150mm bearing at each end. The selected lintel must also have sufficient safe working load for the construction above.
Installation and concrete floor support
Check the cavity width, masonry leaf dimensions and supporting wall construction before installation. Follow Catnic's current guidance for end bearings, temporary propping and restraint.
When using Catnic CH and CX open-back lintels with concrete floors, build the blockwork tightly against the inner vertical face of the lintel. A mortar joint at the top of the blockwork helps distribute floor-unit loads evenly over the inner flange.
