Catnic standard duty thinjoint lintel for 90-105mm cavity wall
Standard Duty Steel Lintel

CTJ90

Description
Standard duty steel lintels for use in thin joint masonry cavity wall construction with 102mm outer leaf. Inner leaf support is achieved through a standard Catnic box lintel and propping during construction is eliminated thanks to a unique plastic fixings connection. The CTJ range closes the cavity and removes the need for an additional cavity closer. Fully insulated, with integral plaster key and built in DPC thanks to Catnic's signature black powder coating.

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.
