Astragal Seals for Double Door Applications

UNILOCK astragal seals are engineered to provide effective sealing between the meeting stiles of double doors, improving acoustic insulation, smoke containment and fire protection. Designed for commercial, residential and industrial applications, these sealing systems help minimise air leakage while maintaining smooth door operation.

Astragal seals play an essential role in creating a continuous seal where two door leaves meet. When properly installed, they help reduce sound transmission, improve environmental sealing and support the performance of fire-rated door assemblies.

Acoustic Performance

Even small gaps between double doors can significantly reduce acoustic performance. UNILOCK astragal seals minimise airborne sound leakage through the meeting stile, helping create quieter and more comfortable interior spaces.

Typical applications include:

• Hotels and Resorts

• Hospitals and Healthcare Facilities

• Commercial Offices

• Meeting Rooms

• Educational Buildings

• Residential Developments

• Apartments

• Data Centres

• Cinemas
