Standard duty load IG Lintel L1/S50 Cavity Wall Lintel for use in cavity widths within walls up to 275mm wide.

The L1/S50 is designed for use in constructions with a 100-115mm inner leaf, 50-65mm cavity, and 100-105mm outer leaf. The L1/S50 top-hat profile offers robust internal and outer leaf support for wall cavities in masonry construction projects. A thermal break plate enhances thermal performance by eliminating heat transfer from external to inner leaf and vice versa.

The L1/S50 Lintel should have end bearings of at least 150mm for optimal support. Lintels can be propped to facilitate the speed of construction, and other standard best practices should be used.
