IG Lintel L1/S 100 1200mm

The IG L1/S 100 1200mm is a practical standard-duty lintel for smaller openings in cavity wall construction. It is designed for cavity widths from 90–105mm and works with a 102mm outer leaf and 100mm inner leaf, making it a useful choice for everyday residential building, extension and refurbishment work.

For the 1200mm length, IG lists a height of 87mm and a steel thickness of 1.6mm. Published total UDL figures are 12kN at a 3:1 load ratio and 10kN at 19:1.

Use this lintel where the project specification calls for the L1/S 100 standard-load profile.

Installation should follow IG guidance and the project design, including the correct end bearing, DPC and masonry detailing.
