Thermal bridging occurs when a wall, for example, is interrupted by other materials such as a stud-and track system. Built-up systems have external layers that are attached through fixings. This creates thermal bridge, letting heat travel through the insulation, which reduces energy efficiency. Built-up solutions can end up with an R value that is less than half of the product’s declared R value due to thermal bridging, compromising their ability to comply with the new NCC requirements.
Because Kingspan Insulated Panels systems are all-in-one, there is no thermal bridging. To achieve the same R values and HVAC/energy performance in a built-up system would require a significantly thicker wall compared with Kingspan insulated panels. This means Kingspan offers the best and simplest solution to meet R value requirements in the new NCC.
