Sun Fukusukeya Strengthens Supply of Next-Generation SD Insulation Panels Amid Middle East-Driven Material Shortages

Sun Fukusukeya Co., Ltd. of Yachiyo, Chiba Prefecture, led by Representative Director Mitsuo Itakura, announced that from May 2026 it will further strengthen the supply system for its next-generation insulation panel, SD Panel, which is made using offcuts. The move responds to tightening insulation material supply caused by escalating tensions in the Middle East and is intended to help builders and construction companies address procurement challenges. Instability in the Middle East is directly linked to fluctuations in crude oil prices, driving up manufacturing costs and disrupting supply chains for foam plastic insulation materials that rely mainly on petroleum as a raw material. Major domestic insulation manufacturers in Japan have announced successive price increases and order restrictions for some products, while construction sites are increasingly reporting difficulty securing materials and delivery delays. Such conditions may not only raise construction costs but also delay housing supply plans and make quality control harder to maintain. SD Panel offers a solution to these market challenges. The product is manufactured by recycling 100% of insulation material offcuts that would otherwise be discarded, greatly reducing dependence on petrochemical products. This production process enables stable raw material procurement that is less vulnerable to international conditions. The main benefits of SD Panel include stable supply that is resilient to geopolitical risk. Its main raw material is insulation offcuts generated within Japan, allowing continued stable production and supply without being affected by overseas petroleum import conditions or changes in international affairs. It also offers economic advantages that help absorb rising costs. By effectively using offcuts, raw material costs can be significantly reduced, allowing the product to maintain competitive pricing even amid rising insulation prices. Compared with general insulation panels, it is expected to reduce costs by around 30%, strongly supporting builders facing severe material price increases. In addition, SD Panel maintains high insulation performance. Recycled materials are compressed and processed using proprietary technology to retain the insulation performance required for new construction and renovation. In a thermal transmittance test conducted by the Central Laboratory of the Japan Testing Center for Construction Materials, the product recorded a value of 0.38 and complies with the revised Building Standards Act and new insulation standards scheduled to take effect in April 2025. Representative Director Mitsuo Itakura stated that through the strengthened supply system for SD Panel, Sun Fukusukeya will help the construction industry overcome difficult conditions and contribute to the creation of safe and comfortable homes. The company encourages use of SD Panel in construction projects pursuing both sustainability and economic rationality. The product name is SD Panel. It is a next-generation panel made by recycling 100% of insulation offcuts generated in Japan, combining stable supply independent of petroleum raw materials with high insulation performance. Its applications include interior and exterior insulation for homes and buildings, as well as new construction and renovation work. It complies with the 2025 revised Building Standards Act and new insulation standards, with a thermal transmittance value of 0.38.
