The NOR810dB+ is our premium acoustic drop seal, achieving incredible sound reduction of up to 48dB. It has a light weight mechanism which is self levelling to combat sloped floors easily.
Routed into the bottom of a door, the seal is unobtrusive and functions automatically when the door is closed via a side 'activator' that contacts against the door frame. This helps the seal to cause less friction with the floor. It has passed a 500,000 cycle test with ease.
The NOR810dB+ acoustic door seal is adjustable to suit the gap size needed from 1mm up to 13mm and will not only act as an acoustic barrier but also help keep out drafts and keep in energy.
Screen colour may differ from actual product colour. All technical information is given as guidance only. Due to the technical nature of our products they are designed to be installed by a professional.
The NOR810 automatic drop seal will extend to a maximum of 15mm.
14mm wide by 35mm deep.
The black actuator button also acts as an adjusting rod, simply pull the button away from the unit and twist it a full 180degree;. Anti-clockwise to lengthen and clockwise to shorten, repeat until desired drop level is reached.
