Building Thermal Insulation Market Growth Driven by Green Certifications

The global building thermal insulation market was valued at USD 26.9 billion in 2024 and is projected to reach USD 37.8 billion by 2030, growing at a CAGR of 5.9% from 2025 to 2030. The market growth is primarily driven by increasing residential and commercial applications aimed at reducing overall energy costs and the rising awareness of energy conservation.

Favorable government regulations targeting energy efficiency continue to support market expansion. Building insulation minimizes reliance on heating, ventilation, and air conditioning (HVAC) systems, significantly lowering overall energy consumption.

Growing concerns about the environmental impact of insulation materials are encouraging manufacturers to develop eco-friendly and recyclable alternatives. The rising prices of plastic foam insulation materials are further prompting the shift toward green, biodegradable, and recyclable products, strengthening the threat of substitutes in the market.
