Driver: Growing construction of green budlings
There is a global increase in the construction of green buildings due to volatile and high energy prices, concerns about environmental impact, and the health and comfort of occupants. Green building rating systems, such as the Building Research Establishment Environment Assessment Methodology (BREEAM) in the UK, Leadership in Energy and Environmental Design (LEED) in the US and Canada, Deutsche Gesellschaft für Nachhaltiges Bauen (DGNB) in Germany, and the Comprehensive Assessment System for Building Environmental Efficiency (CASBEE) in Japan, are driving this growth.
Restraint: Fluctuation in prices of plastic foam
There is a lack of awareness among consumers and building professionals about building thermal insulation materials. The most significant gap between regulations and recommended energy performance is found in Southern Europe. A major initiative is needed to raise awareness and bring building regulations in line with the findings of Ecofys VII (Ecofys is an innovative and creative company, creating smart, effective, and practically sustainable solutions across renewable energy, energy, and carbon efficiency).
Opportunity: High energy requirement
The energy cost is rising due to high demand in Europe and North America. Building thermal insulation is used to mitigate the high energy requirement, as buildings account for 40% of total energy consumption. The significant factors that increase the use of building thermal insulation are the scarcity of energy, the high cost of energy, and increasing pressure to reduce global warming caused by the use of fossil fuels. Europe and North America depend on imported energy due to their increased consumption. Currently, technology and awareness have significantly reduced energy consumption in buildings through better insulation while improving comfort levels. These factors have led different countries to place energy very high on the political agenda.
Challenge: Lack of awareness about building thermal insulation
There is limited awareness among consumers and building professionals about building thermal insulation materials. The most significant gap between regulations and recommended energy performance is in Southern Europe. A major initiative is needed to raise awareness and align building regulations with the findings of Ecofys VII (Ecofys is an innovative and creative company, creating smart, effective, and practically sustainable solutions across renewable energy, energy, and carbon efficiency).

MARKET SEGMENTS
Source: Secondary Research, Interviews with Experts, MarketsandMarkets Analysis
Building Thermal Insulation Market, By Material Type
Plastic foam held the largest share of value among material types in the global building thermal insulation market in 2025. This is primarily because it offers an optimal combination of high thermal performance, lightweight construction, cost-effectiveness, moisture resistance, and ease of installation. Its widespread use across residential, commercial, and industrial buildings, particularly in roofs, walls, and foundations, has made it the largest insulation material category in many countries.
Building Thermal Insulation Market, By Building Type
In 2025, the residential building segment held the largest share of the building thermal insulation market. This is due to housing making up the biggest part of the global building stock and ongoing new construction. Additionally, homeowners and governments are increasingly focusing on energy efficiency, reducing utility costs, and enhancing indoor comfort. Residential buildings need insulation for walls, roofs, and floors, which continues to drive the demand for thermal insulation materials.
Building Thermal Insulation Market, By Application
The market share of wall insulation was largest in 2025. This is because walls constitute the largest surface area of a building envelope and are responsible for a significant share of heat transfer between indoor and outdoor environments. Insulating walls substantially reduce heating and cooling energy consumption, improve occupant comfort, and help buildings comply with increasingly stringent energy-efficiency regulations.
REGION
Europe accounted for the largest share of the global building thermal insulation market in 2025
Europe led the global building thermal insulation market in 2025 due to strict building codes and the development of green energy buildings. This leadership is attributed to industrial expansion, growth in the construction industry, and favorable government policies supporting insulation-related activities. The presence of leading manufacturers and large production plants also contributed to this market dominance.

Market Definition
According to the Climate Technology Centre and Network (CTCN), building thermal insulation is an important technology that reduces energy consumption in buildings by preventing heat gain or loss. It is used to reduce the amount of power required to heat or cool homes and to minimize heat loss in winter and hot-air penetration in summer. Building insulation tends to be the most cost-effective measure in climates with wide temperature ranges. The impact of additional insulation is significant in buildings with thin walls or timber construction. The insulation’s resistance to heat flow is measured or rated by its thermal resistance, or R-value. The higher the R-value, the greater the heat resistance and the less the heat flow.
