Thermally Broken Lintels
Catnic’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.
- Industry leading linear thermal transmittance Psi values of 0.02 to 0.05 W/mK
- Safe working loads in line with Catnic’s existing Cavity wall lintels
- Manufactured from powder coated galvanised steel
- Options are available to suit cavities from 90 to 165mm, in standard, heavy and extra heavy duty performance categories
This unique design enables a complete thermal break between the inner and outer leaf of the cavity wall construction, results in outstanding thermal performance values of:
Psi value 0.02 to 0.05 W/mK
