Thermo swing insulation slashes energy bills dramatically

How Thermo Swing Insulation Works

The principle behind thermo swing insulation is relatively simple yet highly effective. PCMs embedded in the insulation material change phases—typically from solid to liquid and back—at specific temperatures. During the day, when temperatures rise, the material absorbs excess heat, preventing it from penetrating indoor spaces. At night, as temperatures drop, the stored heat is released, maintaining a comfortable indoor climate. This cyclical process reduces reliance on HVAC systems, which are major contributors to energy consumption in homes and commercial buildings.
