  • The SWL (safe working load) is based on the total UDL (uniform distributed load) over maximum span using 150mm end bearings.
  • Standard lengths are available in increments of 150mm at lengths up to 3000mm, 300mm at lengths from 3000mm - 4800mm (including 4575 but excluding 4500mm).
  • CTF lintels should be suitably propped and secured with provided restraint clips and timber batten (not provided) during construction.

  • It is possible to reuse all of our lintels, providing that they are not damaged. Contact our technical team for more information

Features

Catnic standard duty timber frame lintel for 50-65mm cavity wall shown in situ
  • Built-in Damp Proof Course (DPC) Profile

    Many Catnic lintels offer a unique profile shape that combine with the unique Duplex Corrosion Protection or stainless steel to create an effective barrier that acts 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.

  • Duplex Corrosion Protection

    A coating of thermal setting polyester powder is then applied by an electrostatic process, further protecting the lintel.

Video Guides

When selecting a lintel, there are three factors that should be considered to ensure the correct specification: the type of wall construction, the dimensions of the structural opening and the total load on the lintel. In this video, we run you through the lintel selection process.

Once you have chosen the correct lintel for your project, it is crucial that the lintel be installed properly – if it is not, it could lead to serious issues for the building. In this video, we explain the installation considerations for cavity wall lintels.

Catnic’s Thermally Broken Lintel is the only lintel on the market to provide a complete thermal break between the inner and outer leafs. In this video, we outline the key benefits of Thermally Broken Lintels and explain the installation process.

Steel lintels, and specifically Catnic's thermally broken lintels, have a significant role to play in reducing thermal bridging and achieving carbon gains. They represent one of the simplest and most economical ways for building fabric to be designed and constructed to help achieve the carbon gains necessary to meet current and future building regulations.
