Growth in the building thermal insulation industry has been observed due to rising demand for energy-efficient buildings and the prevalence of stringent building codes in developed nations. Moreover, rising construction activity, accompanied by a growing focus on decarbonization, is another factor driving market demand. The need to reduce energy consumption and improve occupants’ comfort is also driving the building thermal insulation market. The rise in manufacturing and infrastructure activities in developing economies further supports market growth.

By material type, the glass wool segment accounted for the second-largest market share of the building thermal insulation market.

By material type, the glass wool segment accounted for the second-largest market share in building thermal insulation. It offers an optimal balance of thermal insulation, fire resistance, acoustic performance, and ease of installation. Glass wool is the preferred choice for applications where fire safety and sound insulation are equally important, particularly in residential and commercial buildings.

By building type, the non-residential segment accounted for the second-largest market share.

Non-residential buildings held the second-largest share of the building thermal insulation market in 2025 by value. This is mainly because commercial, institutional, and industrial buildings require high-performance insulation to meet stringent building codes, reduce operating costs, and satisfy fire-safety and acoustic requirements. Non-residential buildings consume a substantial volume of insulation because they have large floor areas and complex building structures, with insulation requirements that vary.

By application, the roof insulation segment accounted for a substantial market share.

Roof insulation accounted for a substantial share of the building thermal insulation market in 2025. The roof is one of the most critical parts of the building envelope for controlling heat gain or loss. It provides substantial energy savings, improves indoor comfort, and is one of the most cost-effective energy measures that can be taken in both retrofit projects and new construction.
