Acoustic Seals | Acoustic Sealant

Acoustic Seals

Acoustic seals are designed to close the small gaps around a door where unwanted sound can pass from one room to another. Used as part of a suitable acoustic door assembly, they can help reduce sound transmission and create a more effective barrier against everyday noise.

Our range includes acoustic perimeter seals, drop seals, acoustic sealing products and solutions for the door bottom. Options are available for residential, commercial and other building applications where improved control of noise transmission is required.

Acoustic Perimeter Seals

An acoustic perimeter seal is fitted around the sides and head of a door to minimise gaps when the door is closed. By creating consistent contact between the door and frame, the seal helps restrict common paths through which airborne sound can travel.

For a more complete installation, perimeter products can be combined with a suitable door bottom seal to address gaps around different parts of the door.

Acoustic Drop Seals for Door Bottoms

Acoustic drop seals provide a practical way of sealing the gap beneath a door. A drop-down bottom seal is designed to lower when the door closes, creating a barrier across the door bottom, before retracting as the door opens.

This makes drop seals particularly useful where a permanent threshold could interfere with everyday access. Depending on the product and installation requirements, options may include surface-mounted or rebated designs.

Acoustic Door Seals for Noise Control

A well-planned acoustic door system needs attention to the gaps around the entire door leaf. Combining perimeter sealing with an appropriate door bottom seal can help provide more consistent acoustic sealing around the opening.

Acoustic Smoke and Fire Seal Options

Some products combine acoustic performance with additional smoke or fire-sealing functions. These acoustic smoke and fire seal products can be useful where a door assembly has more than one performance requirement.

Where fire performance is required, always select products appropriate for the specified door assembly and follow the relevant manufacturer's installation instructions. You can also explore our dedicated fire door seals for further options.

Acoustic Sealant

Acoustic sealant is a practical solution for sealing gaps, joints and potential sound-leakage points in walls, ceilings, floors and around suitable building components. Designed to support acoustic insulation, it helps reduce the passage of unwanted noise by creating a flexible, effective seal.

Choosing the Right Acoustic Seal

Before choosing an acoustic seal, check where the unwanted gap occurs, the door construction and the installation method required. Perimeter seals address gaps around the frame, while an acoustic drop or threshold-style solution is designed for the bottom of the door. For specialist applications, always check the individual product specifications to ensure the seal is suitable for the intended door and performance requirements.

FAQs About Acoustic Seals

What are acoustic seals used for?

Acoustic seals are used to close gaps around doors and other suitable openings that can allow sound to pass through. Correct sealing can help reduce unwanted noise transmission as part of a properly designed acoustic system.

Where should acoustic door seals be fitted?

Depending on the product, an acoustic seal may be fitted around the head and sides of the door frame or at the bottom of the door. Combining perimeter and bottom sealing can help address multiple sound leakage paths.

What is an acoustic drop seal?

An acoustic drop seal is a door-bottom sealing product that lowers towards the floor or threshold as the door closes. It helps create a barrier beneath the door while allowing the seal to retract when the door opens.

What is the difference between perimeter and drop seals?

An acoustic perimeter seal is generally used around the sides and top of the door, whereas a drop seal addresses the gap beneath it. They may be used together where a more complete acoustic sealing arrangement is required.

How do I choose the correct acoustic door seal?

Consider the location and size of the gap, door type, required acoustic performance and fitting method. For fire-rated or other performance-critical doors, choose compatible products according to the door manufacturer's requirements and relevant product documentation.
