Keystone Lintels is a leading manufacturer of steel lintels, founded in 1989. The short history of Keystone has been one of relentless expansion and continous innovation whilst redefining the meaning of service in the lintel industry.
Production facilities in Cookstown, Northern Ireland and Swadlincote, Derbyshire provide our customers with a reliable and efficient supply chain. Keystone Lintels offers a range of steel lintels, special lintels, sun lounge lintels and brick feature lintels.
Keystone Lintels has redefined lintel performance with Hi-therm+, the low cost solution to reduced carbon emissions and improved fabric efficiency.
The award winning Hi-therm+ lintel is up to 5 times more efficient than a standard steel lintel and is the only BBA Approved one piece lintel solution which achieves the appendix R value for steel lintels in Part L 2013.
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.
The Hi-therm+ 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.
