Perimeter Seals

Perimeter seals are a fundamental component of high-performance door systems, designed to provide a continuous barrier around the top and sides of a door frame. These seals are essential for improving acoustic insulation, energy efficiency, fire and smoke containment, and protection against dust, air, insects, and light infiltration. At John Barnes Group, we supply a comprehensive range of premium perimeter seals from trusted manufacturers such as Kilargo, Lorient, and Raven—brands known for delivering reliable, code-compliant solutions across commercial, institutional, and residential projects.

Whether you're specifying seals for a hospital, hotel, school, apartment block, or private residence, perimeter seals are a critical inclusion for achieving functional, safe, and comfortable building environments. Buy Perimeter Seals online today from the John Barnes online shop!

What Are Perimeter Seals?

Perimeter seals are installed along the head and jambs of a door frame to seal the gaps between the door leaf and the frame when the door is closed. They work in conjunction with door bottom seals, meeting stile seals, and threshold plates to form a complete sealing system.

Available in a wide variety of profiles, materials, and performance ratings, perimeter seals can be surface-mounted, semi-rebated, or fully concealed to suit the specific needs of the application.

Types of Perimeter Seals

Buy Surface-Mounted Seals online

Easily retrofitted to existing doors, these seals are applied directly to the face of the frame and are ideal for upgrade projects.

Use cases:

• Office fit-outs

• Schools and classrooms

• Residential renovations

Buy Rebated and Concealed Seals online

Installed within the door frame rebate, these seals are discreet and highly effective. Preferred for new builds and high-spec projects where aesthetics matter.

Use cases:

• Hotels and hospitality

• Health care facilities

• Luxury apartments

Buy Fire and Smoke Seals online

Designed to expand under heat and prevent the passage of smoke or flames through the door gaps. These seals are tested to AS1530.4 and AS1530.7 and are typically required in fire-rated door assemblies.

Use cases:

• Fire egress routes

• Inter-tenancy doors

• Server rooms and switchboards

Buy Acoustic Seals online

Seals designed to reduce airborne sound transmission, commonly used in doors requiring high RW ratings for acoustic privacy.

Use cases:

• Recording studios

• Boardrooms

• Multi-residential developments

Buy Combination Seals online

Products that offer multiple protective functions (e.g., fire, smoke, and acoustic), reducing the need for multiple separate components.

Use cases:

• Educational facilities

• Public buildings

• Government offices

Material Options and Performance

Silicone and Rubber Seals

Flexible and durable with excellent acoustic and smoke-blocking properties. Silicone retains performance in high-temperature environments, making it ideal for fire-rated doors.

Magnetic Seals

Offer high acoustic and air sealing performance, particularly effective in applications with precise door alignment and consistent closing force.

Brush Seals

Common for dust, insect, and light control. While less effective acoustically, they are suitable for utility spaces and non-critical doors.

PVC and EPDM

Durable synthetic rubbers used in a variety of compression seal profiles. Effective for thermal, acoustic, and general-purpose sealing.

Applications: Residential vs Commercial

Residential Applications

In homes and multi-residential buildings, perimeter seals support comfort and privacy:

• Acoustic isolation between rooms or apartments

• Energy efficiency through air and thermal control

• Enhanced comfort in bedrooms, home theatres, and study spaces

Commercial Applications

In public and commercial spaces, perimeter seals are a key requirement for safety and compliance:

• Fire-rated corridor and stairwell doors

• Offices and conference rooms with acoustic privacy requirements

• Retail and hospitality venues maintaining conditioned air

• Hospitals and laboratories requiring smoke and air containment
