This acoustic perimeter seal is designed for door bottom gaps, providing a barrier against airborne sound, smoke and energy loss. The mechanical drop-seal system automatically lowers the inner sealing strip when the door closes and retracts it when opened, ensuring a tight seal without affecting the door’s appearance. The seal can be fully hidden in a door bottom groove for a clean finish.
The seal accommodates gaps from 0mm to 10mm, with standard lengths of 2100mm to 2500mm. Materials include silicone rubber or EPDM, both chosen for their durability and acoustic properties. The installation uses screws with a decorative strip to conceal fasteners, maintaining aesthetics. This design is typical for high-performance acoustic doors in commercial or industrial settings.
Primary applications include soundproof doors in recording studios, theatres, offices and healthcare facilities where noise leakage must be minimised. Buyers often pair these seals with acoustic door sets to achieve specified STC ratings. The product is supplied in linear metres, with custom lengths and materials available upon request.

Before ordering, confirm the seal’s compatibility with your door type (plain or rebated) and gap size. Request acoustic test data to ensure the seal meets your project’s STC or sound reduction targets. For fire-rated doors, verify compliance with local building codes and request relevant certifications.
Agree on Incoterms (e.g., FOB Ningbo) and packaging details, as seals are typically shipped in coils or straight lengths. For large orders, discuss palletisation and protection against kinking or deformation. Lead times for custom lengths or materials may exceed standard production, so plan accordingly.
Inspect a sample for material quality, dimensions and the automatic mechanism’s smooth operation. For quality control, check the seal’s hardness (typical 60-70 Shore A for EPDM, 50-60 for silicone) and verify the gap accommodation with a caliper. Request a certificate of conformity and material test reports for the rubber compound.
