Ancon Cavity Wall Lintels

Application

  • Suitable for most domestic and commercial developments and framed structures.
  • Lintels should be firmly bedded in mortar with a minimum 150 mm end bearing onto a full brick or block. Consult Ancon when using limited bearing. The front and back of the lintel must be level before proceeding and a separate DPC incorporated if required.
  • 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 25 mm and blockwork should be built as close as possible to the upstand. Point loads should be applied at least 150 mm above lintel flanges.
  • Although the lintels have a drip edge on the external flange to shed moisture, the junction of the window head and lintel should be sealed with a suitable mastic, to prevent driving rain penetration. Weep vents should be provided above lintels at maximum 450 mm centres. Each opening should have at least two weep holes and stop ends are required to prevent moisture penetration.
  • Long spanning lintels will require propping during installation to limit deflections.

Description

A stainless steel lintel for cavity walls.


Features and benefits:

  • Perforations in the inner flange offer an integral plaster key.
  • SH lintels require a separate dpc, while SU and SUX lintels have a built in DPC.
  • Manufactured from Austenitic stainless steel and will not require any further corrosion protection.

Characteristics

-

Thermal conductivity

The thermal transmittance of the wall depends on the thermal characteristics of the individual components. Ancon Cavity Wall Lintels allow for continuity of construction down to window head level.

Insulation

Not required.

Required.

Where required, Cavity Wall Lintels are supplied insulated with high-density polystyrene, manufactured in accordance with BS 3837-1:2004 to be CFC-free with an ozone depletion potential (ODP) of zero.
