Drop Down Seals or threshold seals are designed to work in conjunction with a perimeter seal and where practical a threshold plate. With acoustics, unlike fire and smoke sealing it is essential you seal the threshold of a door as sound will make its way through any crevice available. This automatic drop down seal is light weight with a self-levelling mechanism. This seal has passed a 100,000 cycle test with ease.
The acoustic door seal is adjustable to suit the gap size needed and will not only act as an acoustic barrier but also help keep out drafts and keep in energy!
