Thin Joint Lintels

Description

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. The 'C section' is used for the inner leaf whereas the insulated angle lintel is used for the cavity and outer leaf. The Thin Joint Lintel must be used in conjunction with lateral restraint clips. Allowance should be made for the movement of the entire structure due to settlement and shrinkage. The Thin Joint lintel is also recommended for thin mortar joint construction where joints are between 2–6 mm. This is particularly common when aerated blockwork is used. Thin Joint lintels are manufactured from pre-galvanized mild steel to BS EN 10346: 2009 DX51D plus Z600, or grade Z275 to BS 5977-2: 1983 (BS EN 845-2: 2003). There is a minimum galvanized zinc coating of 600 g/m² on both sides. If stainless steel lintels are required, IG utilize stainless steel grade 1.4307 to BS EN 10088-2. Thin Joint Lintels are insulated with expanded polystyrene and conform to BS 13163: 2008.

Technical characteristics:

For Uniformly Distributed Load (UDL) figures, height and thickness of lintel ranges, consult manufacturers literature for details.

Thermal performance:

The Thin Joint lintel performs very well thermally as a thermal break has been created between the inner and outer leaf. As the Thin Joint lintel can be classified as two separate lintels there is no continuous steelwork from the outer to the inner leaf.
