Insulation Materials Business

Business Overview

Glass wool, made by flocculating glass into a cotton-like material, has high heat insulation performance. It also has excellent nonflammable and sound-absorbent qualities, and is used for a wide range of purposes in structures such as houses and other buildings, as well as in vessels and vehicles. Glass wool is a material that contributes to energy saving by improving the effectiveness of indoor heating and air conditioning, which it achieves by blocking the transfer of heat between indoor and outdoor settings and inhibiting the conveyance of outside heat and cold to indoor settings.
Nittobo Group company Paramount Glass Manufacturing Co., Ltd. is responsible for the development and sale of glass wool.

Development of New High-Performance Insulation Materials

Glass wool is a material that contributes to energy savings by improving the effectiveness of indoor heating and air conditioning, which it achieves by blocking the transfer of heat between indoor and outdoor settings and inhibiting the conveyance of outside heat and cold to indoor settings.
Japan’s Act on the Improvement of Energy Consumption Performance of Buildings (Building Energy Efficiency Act) was enacted in 2015 to enhance global warming countermeasures. There is now an increasing need for insulation materials with improved performance, with developments including it having become compulsory in 2022 for all new residential construction to conform to the highest conventional insulation grade by 2025, and the establishment of even higher thermal insulation ratings.
Paramount Glass Manufacturing Co., Ltd. is developing high-performance insulation materials to facilitate responses to these circumstances. While maintaining the inherent properties of glass wool, namely nonflammable, heat resistance, and high durability, they achieve insulation performance superior to that of other materials, and these materials will also be made compatible with the newly-established high thermal insulation ratings. High-performance insulation materials can be expected to improve heat insulation performance by approximately 30% compared with conventional glass wool.
