IG L1/TJ 50 Thin Joint Lintel
For 50-65mm cavity, Manufactured length in 150mm increments
For standard loading conditions in 50mm wide thin joint cavity wall construction. To achieve loading figures lintels must be built in as shown with firmly butted perpendicular joints. The L1 /TJ lintel range can be supplied to suit wider cavities e.g. specify L1/TJ 70, L1/TJ 90. Lintels may be propped to facilitate speed of construction.
Designed for fast-track construction the thin joint lintel can be used as two separate lintels when the contractor chooses to build and complete the inner leaf of the building prior to starting the outer leaf.
