Soundproof Steel Door DST-T3
A genuine soundproof door with 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 that includes 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 secured. It can also be equipped with a door check as an option and can be used as a specific fire protection 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 realized due to uneven flooring. *2 We believe that it meets the requirements for specific fire protection facilities, but opinions may vary depending on the administrative agency conducting the inspection, so please be sure to check with the administrative agency in your installation area in advance.
