Insulation Board "Ractee"
High-performance urethane insulation board born from the "voices" of the field.
"Ractee" is a polyurethane insulation board that excels in workability, water resistance, and thermal insulation performance, developed based on the opinions of those who implement it on-site. It adopts non-woven fabric (moisture-permeable waterproof sheet), which is now used in most residential exterior walls, as a protective material for insulation. This enhances the water resistance of the already water-resistant polyurethane insulation material. 【Features】 ■ Non-fluorinated polyurethane ■ The shape of the board's side makes it easy to push in ■ Equipped with fins (edges) to prevent slippage over the long term ■ Water-resistant insulation material with non-woven fabric and rigid polyurethane independent bubbles ■ Smooth flow from installation to mounting ■ Product lineup that meets higher insulation grades for each region ■ Insulation thickness of 80mm for walls that meet the specifications of the guidance standards for regions 1 and 2 will be released in April 2025 *For more details, please refer to the PDF document or feel free to contact us.

The Mirai Eco Housing 2026 project has been established as a successor to the Child-Rearing Green Project.
As a successor project to the Child-Rearing Green Business, subsidies for the construction of energy-efficient homes and support for energy-efficient home renovations have been announced. The Housing Energy Efficiency 2026 Campaign, a collaboration among three ministries, has strengthened support for housing energy efficiency with a supplementary budget of 378 billion yen for fiscal year 2025. Construction that begins on or after November 28, 2025, will be eligible, and a key change to note is that the condition for starting new construction is now based on the commencement of foundation work. The total budget for new construction and the subsidy amount per unit have also been reduced. In the Future Eco Housing 2026 project, which only targets renovations, eligible homes are limited to those that do not meet the energy efficiency standards set in 1999 prior to renovation. Please refer to the related materials summarizing the information available until December 17, 2025.

Request to publish the product specification table containing the product number, insulation thickness, and thermal resistance values in the shipping notice, and to keep the shipping notice on file.
As of April 2025, compliance with energy-saving standards for buildings has become mandatory. Accordingly, compliance with energy-saving standards will be added to the items for completion inspection. During the inspection, you may be asked to present shipping documents from the time of delivery to confirm the specifications and installation status of the insulation materials, so please keep them safe until the inspection is completed. For the insulation thickness and thermal resistance values corresponding to our company's insulation product model numbers, please refer to the attached product specification sheet.

Our thoughts on home building have not changed over time. We aim to provide a living environment where families can live healthily and happily. The polyurethane insulation panels, which are made with a wooden frame and injected as a single molded unit with minimal aging, ensure insulation and suppress the occurrence of condensation, which is the enemy of homes, thereby creating a comfortable living environment for two or three generations. "To be a home worthy of protecting life." Under this strong belief, we strive to be a leading company in comprehensive insulation manufacturing, starting with polyurethane insulation panels, and contribute to "building homes with high asset value" that become family assets and effective social capital.
