Acoustic Sliders - Seals

Lotus’ seal systems eliminate acoustic ‘mouse holes’ inherent in sliding door systems for maximum acoustic performance.

Two seal combinations that suit different site circumstances and acoustic requirements are available, as shown below. The full perimeter of the opening is acoustically sealed at the top and bottom rail as well as the receiving and trailing jambs.
