Market of Thermal Insulation Materials for Housing in Japan: Key Research Findings 2019

Yano Research Institute (the President, Takashi Mizukoshi) has conducted a survey on the domestic market of thermal insulation materials for housing (seven categories) and has found out the shipment volume and value, the trend by category, the trend of the market players, and future outlook.


Market Overview

The domestic market size of thermal insulation materials for housing in FY2018 was estimated as 380,577 tons in volume, an increase by 1.2% from the previous fiscal year, while the market size in value was estimated as 187,600 million yen, a rise by 3.6% from the previous fiscal year.

Frequent revisions to the energy saving standards led not only house suppliers but also the clients (general users) to be conscious of energy-saving houses taking shape. As major house suppliers (or major housing builders) started conforming to “thermal insulation grade 4”, and as the demand for thermal insulation materials expanded such as in ZEH (Net Zero Energy House), the opportunity of and the volume of these materials used per house have increased. Such a favorable environment has expanded the market for FY2018.

Noteworthy Topics

No Confusion Occurred by Postponement of Making New Detached Homes to be Mandatory to Meet Energy-Conservation Standards by 2020

Obligation of newly-built detached houses to conform to the save-energy standard by 2020, which was regarded to boost the market, has been postponed. So far, the market of thermal insulation materials for housing has not shown major confusion.

As the demand for thermally-insulated detached homes is increasing, major house suppliers and housing builders have begun having their houses autonomously meet “thermal insulation grade 4”. Because local and small-and-mid-size builders have followed suit, the demand for residential thermal insulation materials keeps increasing.

In addition, as stipulated in the amendment to the energy conservation act for buildings effective in May 2019, establishment of a system to make architects mandatory to explain the propriety of meeting the energy-saving standards to their clients is expected to increase the awareness as well as the understanding toward the necessity of thermal insulation for housing.

Future Outlook

The domestic market size of thermal insulation materials for housing in FY2019 is likely to increase by 2.7% from the previous fiscal year to attain 390,900 tons in volume, and the market size in value to rise by 4.7% to achieve 196,430 million yen.

Out of the entire thermal insulation materials, 80 to 90% of them is for newly built houses. However, current growth of the thermal insulation materials market is not necessarily proportional to the number of new housing starts. While the number of new housing starts may decrease from the long-term point view, the thermal insulation materials market is expected to expand further because of the favorable the market environment represented by high demand for the houses to be thermally insulated.

Research Outline
