Insulation vs. Thermal Mass

Defining our terms: Insulation : A material with the property of slowing heat transfer. Conventional construction examples: fiberglass insulation batts, foam, cellulose. Natural examples: straw, sheep's wool, pumice. Thermal Mass : A material with the property of absorbing or releasing large quantities of energy when changing temperature.

Thermal mass needs to be combined with other passive design principles (for example, orientation, insulation , appropriate glazing) to be effective. High thermal mass can be incorporated in your floor (for example, concrete slab), walls (for example, feature brick wall or reverse brick veneer construction), or in additions (for example, water ...
Difference Between Thermal Insulation and Thermal Mass

Insulation and thermal mass are the terms related to thermal insulation for home. But people often get confused between both these terms thermal insulation and thermal mass .
Considering thermal mass in building design presents both environmental benefits, such as improving air quality and efficiency, and potential construction cost savings due to the need for reduced insulation and reduced energy usage over the building's life cycle.
