The thermal conductivity of FP copolymer insulation materials is the industry's highest standard at 0.019 W/(m·K). All registered products eligible for insulation renovation subsidies under the Mirai Eco Housing 2026 project have been updated to insulation category F in the announcement of the fourth batch of model numbers on June 30, 2026. Subsidy amounts are 44,000 yen/m³ for exterior walls, 44,000 yen/m³ for roofs and ceilings, and 62,000 yen/m³ for floors. Please utilize Replus boards, which allow for easy insulation renovation from the interior side without damaging the structure. Applications for renovation subsidies (including reservations) will begin on June 30.
