Lintel specification to satisfy Part L requirements

Replacing traditional steel lintels with Catnic Thermally Broken Lintel, the heat loss through the window head detail can be reduced by up to 96%.

On a typical 4 bedroom house with 1200 square feet, the heat loss through a standard lintel can account for about 6%* of the overall heat loss through the fabric of the house. Using a Catnic Thermally broken Lintel reduces this to 0.25% making it effectively insignificant.

*based on a default lintel psi value of 0.5 W/mK

This 30 minute webinar guides specifiers through sustainability of steel, lintel design, performance, applications and correct installation, whilst outlining the latest thermal considerations and enhancements to satisfy Part L requirements
