Hi-therm is the only BBA Approved one piece lintel solution which achieves the appendix R value for steel lintels in Part L 2013. Up to 5 times more thermally efficient than a standard steel cavity wall lintel therefore reducing thermal bridging & improving SAP calculations.
A low cost route to improve both CO2 reduction & Fabric Energy Efficiency standards in line with Part L Building Regulations.
Better buildability – offers the simplicity of a one piece, structurally superior top hat design creating stability during the building process, unlike a two part lintel solution. Hi-therm+ is manufactured with a wider range & longer lengths.
