Keystone’s stellar industry innovation has been showcased by the release of an advanced version of its award-winning Hi-therm Lintel: Hi-therm+.
Keystone Group National Technical & Specification Manager Richard Kinloch has spoken about how the new version maintains all the benefits of the original, but with new features added, therefore widening its appeal.
Hi-therm has scooped multiple awards for its innovation, having made significant impact on the energy efficiency of new homes. This upgraded design offers even better practicality to builders, making its benefits open to even more projects.
“The need to address thermal bridging is becoming a mainstream requirement and is boosting the need for advanced thermally efficient lintels,” said Richard.
“Our R&D team has continued in its quest for perfection and the new re-designed Hi-therm+ Lintel helps meet the growing demand onsite for compliance with Part L 2013 regulations.
“The innovative design of the Hi-therm+ Lintel, while still utilising a rigid polymer thermal insulator as an effective thermal break, now incorporates a steel inner and external leaf. The product is as thermally efficient as the original but is now similar to a standard steel lintel for simplified installation.”
Hi-therm is a patented innovation based around introducing a polymer element into a steel lintel. This creates a powerful thermal break, dramatically reducing thermal bridging through the junction with beneficial cost and performance outcomes.
Richard referred to the benefits of the new design: “Buildability lies at the heart of Hi-therm’s success because what the builder wants is a high performance lintel that can be handled and built on site in exactly the same way as standard lintels.
“Split lintels and other non-structural thermal breaks are not comparable in terms of buildablity and do not offer the simplicity of the Hi-therm lintel. Hi-therm+ takes practicality to a higher level again, so it will be even easier to handle on site than before.
“This is an increasingly important benefit and addresses the challenge of maintaining good detailing when skill levels are under pressure and introducing specialist techniques can be problematic.”
