Catnic product: Thermally Broken Lintels

Project name: Lorton Park

Project type: Multiple housing development

Specifier: AKI Ltd – Property Management Company

Location: Weymouth

Lorton Park development has been designed and built with energy and water conservation in mind. With a particular importance placed on the selection and quality of the materials used, Catnic’s innovative TBL was specified for all 46 luxury properties.

BRE certified, the Catnic TBL range delivers industry leading linear thermal transmittance Psi values of 0.02 to 0.05 W/mK and safe working loads in line with Catnic’s existing Cavity wall lintels.

Chris Watts, Sales Manager at Jewson, worked with Mr Hidari on the product specification,

“After comparing different lintels on the market it became clear that Catnic TBL’s were best suited to the specific project requirements.

“Due to the medium density concrete blocks being used onsite, AKI Ltd needed a product that could meet its thermal performance requirements and easily achieve the build’s load requirements – the composite design of the TBL made it the perfect choice.”

The specifically designed flat top of Catnic’s Thermally Broken Lintel provides a simple, consistent junction with the cavity wall insulation. This removes the reliance on site workmanship, reducing the risk of a ‘performance gap’. There are also no brackets connecting the inner and outer leaf of the lintel and therefore there are no additional point thermal bridges that need to be considered

The large scale development project also benefited from Catnic Lintel Advance Scheduling System (CLASS). Through the fully comprehensive scheduling service, Catnic’s expert team created a concise document which detailed lintel descriptions, price, delivery time and a guaranteed structural accuracy.

“This has been a huge, complex project and we needed a product that could deliver on the specific structural and thermal requirements,” commented Mr Hidari. “As the only lintel on the market with a complete thermal break, it seemed like the ideal product. I was particularly impressed by the Catnic team who provided us with a full design and specification for the entire development.”
