Soundproof Steel Door DST-T3
A professional soundproof door with a sound insulation performance of T - 3 grade, even without a lower frame.
This is a genuine steel soundproof door that meets the JIS sound insulation performance T-3 grade, even with a three-sided frame without a bottom frame. Of course, it also meets the JIS sound insulation performance T-3 grade with a four-sided frame with a bottom frame. By adopting a double packing on the outer frame and incorporating a bottom device to enhance airtightness, the door's sound insulation performance is ensured. It can also be equipped with a door check as an option and can be used as a specific fire prevention facility according to the specified specifications. *1 This is the result of tests conducted by a testing organization and is not a guaranteed value for the installation site. Additionally, the sound insulation performance of the three-sided frame specification may not be fully demonstrated due to uneven flooring. *2 We believe that it meets the requirements for specific fire prevention facilities, but opinions may vary depending on the administrative agency conducting the inspection, so please be sure to confirm with the administrative agency in the installation area in advance.
