Insulation Material
Target Scope
Insulation material (limited to those that use extruded polystyrene foam, rigid polyurethane foam, glass fiber (including glass wool; the same applies hereinafter), slag wool or rock wool), except the following:
1) vacuum insulation material,
2) insulation material using rigid polyurethane foam that have no face material,
3) air-blast type insulation material using rigid polyurethane foam,
4) blow-in type insulation material using glass fiber, slag wool or rock wool, or
5) insulation material using glass fiber that have a density of 24 kg/m3 or more.
Heat Loss Prevention Performance
Heat loss prevention performance shall be thermal conductivity (W/(m・K)) found by the measurement method stipulated in JIS A 9521 (2017).
Categories & Target Standard Values
In the target fiscal year and each subsequent fiscal year, for each category, the weighted average value obtained by weighting heat loss prevention performance with dimension shipped shall not be above the target standard value.
| Category | Category name | [Target standard value] Standard heat loss prevention performance | |
|---|---|---|---|
| Base material | Type | ||
| Extruded polystyrene foam | ― | Extruded polystyrene foam insulation material | 0.03232 |
| Glass fiber | ― | Glass wool insulation material | 0.04156 |
| Slag wool or rock wool | ― | Rock wool insulation material | 0.03781 |
| Rigid polyurethane foam | Type 2 | Rigid urethane foam insulation material – type 2 | 0.02216 |
| Type 3 | Rigid urethane foam insulation material – type 3 | 0.02289 | |

Target Fiscal Year
[Extruded polystyrene foam, glass fiber, slag wool or rock wool-based insulation material]
●FY2022 and each subsequent fiscal year
[Rigid polyurethane foam-based insulation material]
●FY2026 and each subsequent fiscal year
Performance Improvement
●For extruded polystyrene foam insulation material, heat loss prevention performance is expected to be improved by 6.19% compared with the FY2012 level in the target fiscal year (FY2022).
●For glass wool insulation material, heat loss prevention performance is expected to be improved by 6.04% compared with the FY2012 level in the target fiscal year (FY2022).
●For rock wool insulation material, heat loss prevention performance is expected to be improved by 0.50% compared with the FY2012 level in the target fiscal year (FY2022).
●For rigid urethane foam insulation material, heat loss prevention performance of those falling into Type 2 category is expected to be improved by 3.40% and heat loss prevention performance of those falling into Type 3 category is expected to be improved by 4.23% compared with the FY2016 level in the target fiscal year (FY2026).
