Fire & Sound Proofing

Fire & Acoustic Seals for Complete Door Protection

Effective fire and acoustic seals play a critical role in stopping the spread of flames, smoke and sound through door gaps. When correctly installed, fire door seals expand under high temperatures to seal the clearance between the door leaf and frame, helping maintain the integrity of FD30 and FD60 fire doors. Many fire and smoke seals for doors also include brush or fin elements to prevent cold smoke leakage before heat activation occurs.

Fire Door Seal Strip Solutions

A fire door seal strip is typically rebated into the edge of a timber fire door or frame. These strips contain intumescent material that expands when exposed to heat, sealing gaps and slowing fire progression. Selecting the correct size and rating is essential to ensure compliance. Fire acoustic seals combine intumescent protection with smoke and sound control, offering dual performance without compromising appearance. This makes them ideal for apartment blocks, offices, schools and healthcare settings where both safety and acoustic control are required.

Drop Down Fire Door Seals & Threshold Protection

Drop down fire door seals are installed along the bottom edge of the door and automatically lower when the door closes. A fire door drop seal creates a tight seal against the floor, preventing smoke movement and improving acoustic insulation. These solutions are particularly effective where floor gaps are present and where a traditional threshold is not suitable. When paired with perimeter fire door seals, they form a complete barrier system that enhances both fire resistance and noise reduction.

Acoustic Smoke Seal & Sound Proofing Products

In addition to fire performance, many buildings require enhanced sound control. An acoustic smoke seal helps limit airborne noise while also restricting smoke leakage. Smoke & acoustic seals are commonly used in flats, hotels and meeting rooms to improve privacy and comfort. By combining fire proofing products with specialist sound proofing products, you achieve comprehensive protection that supports regulatory compliance and everyday functionality.

Whether you require individual fire door seals or a complete system of fire and acoustic seals, selecting tested and compatible components ensures optimal performance and long term reliability.

Frequently Asked Questions

What is the purpose of a fire door seal?

A fire door seal is designed to expand when exposed to high temperatures, closing the gap between the door and frame to slow the spread of fire and smoke. Fire and smoke seals for doors also restrict cold smoke movement before heat activation, helping maintain fire door integrity and improve overall building safety.

Are drop down fire door seals necessary?

Drop down fire door seals are important where there is a gap at the bottom of the door. A fire door drop seal automatically lowers to seal this gap when the door closes, helping prevent smoke spread and improving acoustic performance without the need for a fixed threshold.

Can fire and acoustic seals improve sound insulation?

Yes, fire and acoustic seals are designed to provide both fire resistance and noise reduction. Smoke & acoustic seals and acoustic smoke seal options help limit airborne sound transfer while maintaining certified fire performance, making them suitable for residential and commercial buildings requiring dual protection.
