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.

Company information
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.
