What term describes insulation used to reduce heat loss?

• A. Acoustic Insulation
• B. Thermal Insulation
• C. Density
• D. Vapour Barrier

Answer: (B)

Thermal insulation reduces heat transfer between spaces, helping to keep indoors warm in winter and cool in summer. It works by presenting high resistance to heat flow, using materials with low thermal conductivity and sufficient thickness, and sometimes air gaps or reflective layers to limit conduction, convection, and radiation. The term for insulation designed to reduce heat loss is thermal insulation. Acoustic insulation focuses on blocking sound, density is a material property that can affect performance but isn’t itself the term for heat loss, and a vapour barrier controls moisture diffusion rather than heat transfer.
