Acoustic Door Seals

Acoustic door seals are designed to minimise sound transmission through gaps around the door. By creating an effective seal between the door leaf and frame, they significantly improve sound insulation and privacy in environments where noise control is essential.

UNILOCK acoustic door seals are widely used in:

• Hotels and resorts

• Hospitals and healthcare facilities

• Offices and meeting rooms

• Educational buildings

• Cinemas and theatres

• Residential homes and apartments

• Data centres

• Recording studios

Combined with high-quality doors and professional installation, our acoustic sealing systems help improve the overall acoustic performance of a door assembly.

Automatic Drop Seals

Automatic drop seals provide an effective seal at the bottom of the door only when the door is closed. This intelligent mechanism reduces sound leakage while maintaining smooth door operation and eliminating unnecessary friction during opening and closing.

UNILOCK automatic drop seals are suitable for:

• Acoustic doors

• Fire-rated doors

• Smoke control doors

• Hotel guest rooms

• Executive offices

• Conference rooms

• Healthcare facilities

• Luxury residential projects

Available in various sizes and finishes, our automatic drop seals are designed for both new installations and retrofit applications.

Fire and Smoke Door Seals

Fire safety is a critical requirement in modern buildings. UNILOCK fire and smoke door seals are engineered to help maintain fire compartmentation and reduce the spread of smoke through door openings during a fire event.

Our sealing systems are suitable for use in commercial buildings, healthcare facilities, educational institutions, hospitality projects and residential developments where fire-rated door assemblies are required.
