EVOLUSION PROVIDE NSAI APPROVED THERMAL MODELLING AND BBA CERTIFIED U-VALUE CALCULATION SERVICES TO ROADSTONE

Evolusion Innovation provided Roadstone with specialist consulting services during the development and promotion of the Thermal Liteblock system. Our expert thermal modellers, who are approved by and registered with NSAI, have thermally modelled each critical junction detail as per the Acceptable Construction Details (ACDs) as listed in TGD L 2011 appendix D1, D2, D4 and D6 and have calculated the psi value for each junction.

We are currently actively assisting Roadstone in providing validated (y) factor calculations for customers using the Roadstone Thermal Liteblock system, with (y) factors as low as 0.03 possible. The benefits of these low (y) factors are evident in the improved DEAP results and the higher BERs achieved. By using the Roadstone Thermal Liteblock System you can comfortably comply with TGD Part L 2011 thermal bridging requirements

Roadstone's innovative
THERMAL LITEBLOCK SYSTEM demonstrates the importance of a Fabric First approach to thermal efficiency in buildings

Energy efficient design begins with a Fabric First Approach, whereby the buildings shape, orientation and thermal mass, with proper detailing, will save energy. The energy saving work is done by the building using high performance fabric rather than relying on mechanical renewable energy systems.

The Roadstone Thermal Liteblock, manufactured in Ireland using a special mix (thermal conductivity (Lambda λ) values of 0.33W/mK), provides a cost-effective solution to improve thermal bridging performance while critically allowing for traditional construction methods to be used. These robust and durable concrete blocks come in 7.5N/mm2 and 13N/mm2 compressive strengths, and there is a wide range of specials available. The reduction in thermal bridging that can be achieved allows designers more flexibility when generating a Part L compliant specification.
