On the first day, Sanwa Holdings <5929> announced that its subsidiary, Sanwa Shutter Industry, will release a door for use in halls, which is suitable for specific fireproof equipment and has a sound insulation grade of T-3.

Doors for halls, such as those for theaters and concert halls, require not only design, but also high sound insulation performance and fireproof performance to prevent spreading of fire during fires. In addition, a wide opening is necessary to ensure that many people can evacuate safely and smoothly. This time, the company added a hall door suitable for specific fireproof equipment to the lineup of high-performance soundproof doors "Soundproof Guard".

The newly released "Soundproof Guard" hall door is a high-performance soundproof door that ensures both safety and functionality by incorporating an original new mechanism called the "Dual Open System" (patent pending) which allows the door to be opened from either the left or right side and is suitable for specific fireproof equipment. In addition, it guarantees a sound insulation grade of T-3.

The company aims to provide safety, security, and comfort, and will continue to provide products from the customer's perspective, based on its mission to contribute to society.

The sales target for the first year after launch is 0.1 billion yen.
