Lämpövuotomateriaalin

Lämpövuotomateriaali is a Finnish term that translates to "heat leak material" or "thermal leakage material" in English. It refers to any substance or material that allows heat to pass through it, facilitating heat transfer. In the context of building science and insulation, it often describes materials that are poor insulators, or conversely, the pathways through which heat can escape or enter a structure.

These materials are significant in discussions about energy efficiency, as minimizing heat leakage is crucial for maintaining comfortable indoor temperatures and reducing heating and cooling costs. Common examples of materials that contribute to heat leakage include gaps in insulation, poorly sealed windows and doors, or building components that have low thermal resistance. Understanding the properties of materials that promote or impede heat flow is essential for effective building design and retrofitting.

The concept is directly related to thermal conductivity, a measure of a material's ability to conduct heat. Materials with high thermal conductivity are considered good conductors of heat and thus act as heat leak materials, while materials with low thermal conductivity are good insulators and resist heat flow. Identifying and addressing areas where heat leaks occur is a primary goal in energy audits and the implementation of insulation strategies.
