In a joint residential building in Yokohama, the installation of solar panels requires domestic waterproof sheets to be replaced every 12 to 13 years, so our product, which offers long-term durability, was used for the installation. The foundations for the additional solar panels were also perfectly constructed using Novotan molded fittings.
