Intumescent Fire Only Seals

Our Intumescent Fire Only Seals by SPARKA UK are available in packs of 5 and 50. These seals are ideal for environments where enhancing the fire resistance of the door assembly is essential. They expand in the event of a fire, sealing off gaps to prevent the passage of flames and hot gases, thereby increasing your door's fire rating.

Intumescent Fire & Smoke Seals

Also from SPARKA UK, the Intumescent Fire & Smoke Seals are available in similar pack sizes. These seals not only expand to prevent fire spread but also have a brush or fin component to restrict smoke movement. Perfect for areas where both fire and smoke protection are crucial.

Lorient Intumescent Strips

Our range from LPD DOORS includes the Lorient Intumescent Fire Strips and Bladed Dual Seals. Available in various sizes and colours, these strips are designed to fit into a rebate on the door or frame, offering a discreet yet effective fire and smoke sealing solution.

Fire Strip FD30

The Lorient Intumescent Fire Strip FD30 is specifically designed to enhance the fire resistance of door assemblies, meeting the 30-minute fire resistance criteria as standard.

Bladed Dual Seal FD30

The Lorient Intumescent Bladed Dual Seal FD30 offers the dual benefit of fire and smoke protection. Its unique design allows for a more efficient seal against both elements.

Pile (Black Brush) FD30

For scenarios demanding a softer touch and smoke seal, the Lorient Intumescent Pile with a Black Brush is the go-to option. Its soft bristles provide a seamless door operation while blocking smoke effectively.

Lorient Drop Seals

Provided by DEANTA, the Lorient Drop Seals come in various sizes to suit different door types. These are perfect for creating an acoustic barrier and sealing the gap between the door bottom and floor, additionally providing some level of smoke and fire resistance.

As experts in door sealing solutions, we recommend considering the specific use case—be it fire resistance, smoke sealing, or acoustic insulation—when selecting the appropriate door brush seal. Remember to check the compatibility with your door's fire rating and dimensions for optimal performance. Our team at Build4Less is always ready to assist you in making the perfect choice for your safety and comfort needs.

What is a Door Brush Seal?

A door brush seal is a strip fitted to the bottom of a door, featuring dense bristles or brush fibres that create a flexible seal against the floor. Unlike rigid seals, brush seals adapt to uneven surfaces, ensuring consistent protection without restricting door movement.

They are widely used in residential, commercial, and industrial applications where insulation, cleanliness, and pest control are important.

Benefits of Door Brush Seals

Improved Energy Efficiency

Door brush seals help block cold air from entering and warm air from escaping, reducing heat loss and lowering energy consumption.

Effective Dust & Insect Barrier

The dense bristles prevent dust, debris, and insects from entering your space, making them ideal for homes, offices, and warehouses.

Noise Reduction

They help minimise sound transfer between rooms or from outside, improving acoustic comfort.

Flexible & Durable Design

Brush seals adapt to uneven floors, making them suitable for a wide range of surfaces including tiles, wood, and concrete.

Easy Installation

Most door brush seals are quick to fit using screws or adhesive backing, making them suitable for DIY installation.

Applications of Door Brush Seals

Door brush seals are versatile and can be used across multiple settings:

• External doors to prevent draughts and weather ingress
• Internal doors for soundproofing and dust control
• Garage doors to block debris and pests
• Commercial and industrial doors for hygiene and insulation
• Workshop and warehouse doors to maintain clean environments

Choosing the Right Door Brush Seal

When selecting a door brush seal, consider the following factors:

• Gap Size: Measure the gap under your door to ensure proper coverage
• Door Type: Choose seals suitable for timber, uPVC, or metal doors
• Fixing Method: Screw-fixed for durability or adhesive for quick installation
• Bristle Length & Density: Thicker bristles offer better sealing performance
• Usage Area: External doors may require more robust, weather-resistant options

Installation Tips

• Measure the width of your door accurately before purchasing
• Trim the seal if required for a perfect fit
• Position the brush so it lightly touches the floor without dragging
• Ensure secure fixing for long-term durability
• Regularly check for wear and replace when necessary
