GPT explains (level =C2; CEFR aligned): Thermal capacity: the fabric’s latent “heat wallet” In building physics, thermal (heat) capacity is the ability of a material to absorb, store and later release sensible heat without undergoing a phase change. Quantitatively it equals the product of density (ρ) and specific heat capacity (cₚ), giving the number of joules required to raise one cubic metre of the substance by one kelvin. High-capacity elements—brick, concrete, rammed earth, even water tanks—act as thermal flywheels, damping indoor temperature swings and shaving peak heating-cooling loads. Crucially, this trait is distinct from thermal conductivity (how fast heat moves through a body) and from thermal resistance (its insulating power); a wall can be both slow to conduct heat and practically unable to store it if its mass is low. Thus “the ability to store heat” is the precise descriptor, whereas “transfer” or “impede transfer” belong to different parameters altogether.
