Reduce carbon emissions and deliver energy efficiency without compromising on design.

What are  Supatherm thermally broken steel lintels? 

In the bid to meet with building regulations, the most obvious energy efficiency solution is to add additional insulation or triple glazing. But did you know you can achieve significant fabric savings simply through your choice of lintel?

Supatherm lintels  are thermally broken lintels that can improve the Dwelling Fabric Energy Efficiency (DFEE) by up to 3% and the overall Dwelling Emission rate (DER) by over 1%* (Based on a typical detached, semi-detached or terraced property)

Due to its unique production and assembly system, Supatherm provides an effective solution without impacting on complex designs such as apex windows or arches. 

What are the benefits of Supatherm thermally broken lintels? 

When more significant fabric savings are needed, our Supatherm range of lintels can reduce heat loss by up to 80% when compared with a standard cavity wall lintel. Based on a typical detached, semi-detached, or terraced property, Supatherm lintels can improve the Dwelling Fabric Energy Efficiency (DFEE) by up to 3%, and the overall Dwelling Emission Rate (DER) by over 1%.

Why choose Supatherm? 

• Up to 80% reduction in heat loss compared with standard cavity wall lintels
• High levels of insulation achieve a far superior PSI value.
• Hot-Dip Galvanized coating to EN1461 as standard
• Options to suit all types of masonry and wall construction 
• All parts and assemblies CE marked to BS EN 845-2
• To suit cavity widths from 90 to 150mm 
• Lengths available from 750 to 3900mm 
• Standard duty, heavy duty and extra heavy duty versions are available 
• Avoids propping associated with single leaf lintels
