Finger Jamb Seals

Finger jamb seals are specialised door sealing components designed to enhance safety, sealing performance, and compliance in door assemblies—particularly where finger-trap protection or fire and smoke containment is required. These seals are typically installed on the hinge side (or jamb side) of the door and provide a protective, compressive seal between the door and the frame. At John Barnes Group, we offer high-quality finger jamb seals from trusted industry manufacturers Kilargo and Lorient, both known for their innovation and strict compliance with Australian Standards.

Whether your project is a high-traffic commercial facility, educational environment, healthcare centre, or multi-residential building, finger jamb seals are a key detail in achieving safe, functional, and compliant openings. Buy Finger Jamb Seals online today from the John Barnes online shop!

 

What Are Finger Jamb Seals?

Finger jamb seals are designed to address two critical needs:

  1. Safety – Preventing fingers, particularly children's, from becoming trapped in the door hinge gap

  2. Sealing – Providing a barrier against smoke, fire, sound, and drafts through the hinge-side clearance

These seals compress as the door closes, maintaining contact with the door and frame while allowing smooth operation. They are often used in combination with other door seals—such as drop seals, perimeter seals, and meeting stile seals—to create a fully sealed and safe door assembly.

 

Types of Finger Jamb Seals

Buy Acoustic Finger Jamb Seals online

These seals support acoustic containment by closing off the hinge-side gap—a known weak point for sound transmission. Used in concert with acoustic drop seals and perimeter seals.

Use cases:

  • Recording studios

  • Conference rooms

  • Hospitality suites

Buy Safety Finger Guards online

Finger protection seals prevent injuries by covering the hinge gap. These flexible seals are ideal for spaces where children, elderly residents, or vulnerable users may be present.

Use cases:

  • Childcare centres

  • Aged care facilities

  • Hospitals and schools

Buy Combination Finger Jamb Seals online

Some products offer dual or triple-function performance: fire, smoke, and acoustic protection, as well as finger protection—all in a single, compact profile.

Use cases:

  • Commercial offices

  • Government buildings

  • Institutional projects

Australian Standards and Compliance

Finger jamb seals contribute to the performance of compliant door systems and are critical in certain regulated environments. Compliance considerations include:

  • AS1530.4: Fire resistance testing

  • AS1530.7: Smoke leakage

  • AS/NZS 1905.1: Fire door assemblies

  • AS1428.1: Design for Access and Mobility – seals must not impede operation of accessible doors

  • Building Code of Australia (BCA): Mandates fire and smoke containment in specified door assemblies

 

Material Considerations

Silicone Rubber

Offers superior durability, heat resistance, and flexibility. Common in fire-rated and acoustic-rated finger jamb seals.

EPDM and TPE

Thermally stable and cost-effective, these materials are used for non-rated or light-rated applications requiring finger protection.

Intumescent Materials

Essential for fire-rated doors, these expand under high heat to close off the hinge-side gap and prevent fire or smoke spread.

 

Applications: Residential vs Commercial

Residential Applications

In multi-residential or premium home applications, finger jamb seals improve comfort, privacy, and compliance:

  • Apartments: Inter-tenancy acoustic control

  • Home theatres: Sound isolation

  • Child-safe homes: Finger protection on nursery or bathroom doors

Commercial Applications

For commercial and public infrastructure, finger jamb seals serve critical safety and performance roles:

  • Schools and childcare: Finger guards to protect young users

  • Hospitals and healthcare: Fire and smoke containment

  • Offices and institutions: Acoustic and smoke protection

 

Selection Guidance

For Architects and Designers

  • Match the seal profile to the door system performance needs (acoustic/fire/safety)

  • Coordinate with other door seals for full perimeter protection

  • Select finishes and materials that align with the project’s aesthetic and operational requirements

For Builders and Installers

  • Confirm compatibility with fire-rated door assemblies

  • Ensure seals are installed at the correct position on the door jamb or frame

  • Choose adhesive or mechanical fixings based on site conditions

For Facility Managers and Residential Clients

  • Choose safety-rated options in settings with children or elderly residents

  • Replace worn or degraded seals to maintain compliance

  • Coordinate with door hardware (hinges, closers, latches) for unobstructed function

 

Installation Tips

  • Clean door and frame surfaces before installation

  • Use manufacturer-approved adhesives or screws

  • Check compression performance and door clearance after fitting

  • Combine with drop seals and perimeter seals for best results

 

Maintenance and Care

  • Regularly inspect for wear, damage, or detachment

  • Clean gently with non-abrasive cleaner and damp cloth

  • Replace any damaged or aged seals to maintain performance and compliance
