We are unable to recommend what type of lintel you require as load bearings from plans have to be calculated in order to obtain the correct duty required. This service is offered at no cost from Keystone’s technical department. A copy of your plans will be required. This will Guarantee that the correct lintel is specified so that failure will not occur.





Hi-Therm Lintels

Keystone leads the way with the development of a completely unique range of lintels to address the thermal requirements of new building regulations which require that lintels should be assessed for their effect on the thermal performance of a building.

Key Benefits:
  • Up to 5 times more thermally efficient than cavity wall lintels.
  • The significant reductions in thermal bridging due to the GRP component will assist in the building design process to achieve compliance with Part L and The Code for Sustainable Homes.
  • The use of Hi-Therm will make a significant contribution to a buildings performance in respect of the Fabric Energy Efficiency Standards (FEES).
  • Outperforms Stainless Steel on price and corrosion resistance.
  • Hi-Therm has achieved the 1 hour fire resistance test as carried out by Exova Warrington fire utilising the heating conditions of BS EN 1363-1 1999
