Building Thermal Insulation Market Forecast to 2027 - Global Trends, Share Analysis, Leading Players, Business Opportunities Building thermal insulation is used to reduce the amount of energy required to heat or cool a house and minimize the amount of heat that escapes during the winter and limits the hot summer air to penetrate the house. Northbrook, IL -- ( SBWIRE ) -- 09|07|2022 -- The global building thermal insulation market will grow to USD 35.3 billion by 2027, at a CAGR of 4.7% from USD 28.0 billion in 2022. Building thermal insulation is used to reduce the amount of energy required to heat or cool a house and minimize the amount of heat that escapes during the winter and limits the hot summer air to penetrate the house. It is the most cost-effective measure in climates that have a wide range of annual average temperatures. The resistance to heat flow of insulation is measured or rated in terms of its thermal resistance or R-value. The higher the R-value, the higher will be heat resistance and better will be the insulation material. Insulation is mainly used in buildings having thin walls and timber constructions.
