Steel Lintels

Thermally Broken Lintels

Thermally Broken LintelsCatnic’s latest innovation is the biggest shake up in steel lintel design for a generation. An elegant, simplistic design derived from extensive research and rigorous development testing, offering a sophisticated, practical solution to the latest changes in Building Regulations. TBL is a patent pending range providing the most thermally efficient steel lintel solution on the market

Utilising steel strength combined with the thermal insulating properties of a high-density, fire retardant core, it’s design provides the thermal performance of separate lintels, whilst offering users the same stable installation benefits of a traditional cavity wall lintel, delivering industry leading linear thermal transmittance Psi values of 0.02 to 0.05 W/mK and safe working loads in line with Catnic’s existing Cavity wall lintels.
