What is continuous insulation and why is it crucial in preventing thermal bridging?In a passive house design, thermal mass plays a crucial role in enhancing energy efficiency through its ability to store and release heat. The materials with high thermal mass, such as concrete, brick, or tile, can absorb heat during the day when the sunlight is at its peak and release it gradually when the temperature drops, thus helping to stabilize the indoor climate. This process reduces the need for additional heating or cooling systems, resulting in lower energy consumption and cost savings over time.

Continuous insulation involves applying insulation without any interruptions, ensuring there are no gaps or weak points where heat can escape, thus minimizing thermal bridging in the building envelope.Moreover, thermal mass assists in regulating the internal temperature of a passive house by acting as a buffer against external temperature fluctuations. By moderating the peak heat gains and losses, thermal mass reduces the demand for active heating or cooling, which in turn lessens the overall energy requirements of the building. This passive thermal regulation not only enhances comfort for occupants but also contributes to a sustainable and environmentally friendly living space.
