Lintels

Cavity Wall Lintels

Cavity wall lintels are suitable for most domestic and commercial developments and framed structures. Perforations in the inner flange offer an integral plaster key.

SH lintels require a separate dpc, while SU and SUX lintels act as a built-in dpc meaning any water penetrating into the cavity automatically transfers across the sloping face of the lintel and is disposed of externally.

When installing cavity wall lintels the inner and outer leaves should be raised together to avoid twisting the lintel; blocks should continue for the full length of the inner flange. Masonry should have a maximum overhang of 25mm and blockwork should be built as close as possible to the upstand. Point loads should be applied at least 150mm above lintel flanges.

For further information and load tables please download the Masonry Support Systems and Lintels brochure from this page or contact our Technical Services Team with your requirements.

Corrosion Resistance

All Ancon Lintels are manufactured from Austenitic stainless steel and will not require any further corrosion protection.

Thermal Performance

The thermal transmittance, i.e. ‘U’ value, of any wall construction depends on the thermal characteristics of the individual components being used. The design of Ancon cavity wall lintels is such that it allows for continuity of construction down to window head level.

Where required, cavity wall lintels are supplied insulated with CFC-free, high density polystyrene manufactured in accordance with BS 3837 : Part 1 : 2004 to be CFC-free with an ozone depletion potential of zero.
