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.
Hi-therm+ is a 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.
Hi-therm+ offers a cost effective solution to lowering carbon emissions within SAP, offering significant savings compared to other popular alternatives.
For example in a comparative case study for a house type, using Hi-therm would incur less than 20% of the cost of increasing the cavity width by 50mm for the same saving in Co². These Co² savings are important within SAP because they give flexibility for compliance in situations where other built details are not meeting the standards in Appendix R.

Maintenance free – No maintenance required unlike other sustainable technologies.
Split lintels – in some cases split lintels may be offered as a means of enhancing thermal performance however they are in no way comparable in terms of efficiency or buildability to the Hi-therm sustainability lintel.
- Hi-therm closes the cavity.
- The single component design simplifies installation.
- The one piece design assists stability between the internal and external leaves and creates stability during the build process.
- Hi-therm+ gives cost certainty with no additional costs.
- A cavity closer must be supplied and fitted.
- Requires two separate lintels with double the handling and installation labour.
- Individual lintels will require propping and additional wall ties will be required to overcome the lack of inherent stability in a split lintel solution.

Specifying Hi-therm significantly reduced thermal bridging on all house types.
“When the government unveiled its changes to Part L 2013 building regulations Barratts analysed a range of sustainable solutions in order to comply with the mandatory minimum fabric performance standard (Target Fabric Energy Efficiency, TFEE). The Hi-therm lintel has proved to offer a cost effective option as part of a suite of specification upgrades.”
