PLANET FT Drop-Down Threshold Seal 950mm 48dB Sound Insulation Trimmable 70095

Product Overview

The PLANET FT drop-down threshold seal is designed for integration at the base of interior and specialized doors in commercial, institutional, and multi-unit residential buildings to provide enhanced acoustic and smoke containment. This model features a silicone automatic seal and can be trimmed from its full length of 950 mm down by up to 10 cm, supporting flexible installation across varying door widths.

The key differentiator of this model is its certified sound insulation capability up to 48 dB, which surpasses the typical performance of standard threshold seals. This high sound attenuation rating reduces procurement risk when specifying for environments with stringent noise control requirements, such as offices, hotels, and music studios. It is particularly suitable for acoustically rated assemblies requiring reliable drop-seal performance and adjustability for retrofit or new-build projects.
