Thermal Bridging and Accredited Construction Details
"Thermal bridging occurs when a conductive building component, such as a steel lintel, spans the gap between the inside and outside of a building, bypassing the insulation.
Thermal Bridging leads to thermal losses from the building increasing CO2 emissions from the building. Condensation can form on the internal wall where there is a thermal bridge leading to damage to the internal decoration.
Accredited Construction Details (ACDs) and Enhanced Construction Details (ECDs) have been introduced to tackle the problem, setting out requirements for reducing thermal bridging in new buildings."
The Cavalok solution:
Cavity closers are the definitive solution to thermal bridging at openings in cavity walls. They are critical to achieving the requirements of the ACDs and ECDs and are stipulated in the regulations.
Closers need to have a thermal conductivity better than 0.45 m2k/W and all Cavalok cavity closers exceed this requirement, thanks to their integral insulating foam. The cavity closer creates a thermal break, which improves the insulation performance and reduces the CO² emissions of a building. What’s more, cavity closers prevent condensation from forming on internal walls.
Compliance with the ACDs allows a defined value to be used in the SAP assesment of carbon emissions from the dwelling. Complying to the superior ECDs promoted by the Energy Saving Trust allows an improve value to be entered. Both of these values give better carbon emission results than if no work was done to improve the thermal bridge.
