Professional Sealing Performance with the FS1/12 12mm Brush Draught Excluder 3M Length Aluminium Carrier
Tackling unwanted draughts, airborne dirt, and intrusive outside sound requires a reliable barrier that can withstand constant physical movement. The FS1/12 12mm Brush Draught Excluder 3M Length Aluminium Carrier delivers a hard wearing, practical sealing system suited to commercial properties, industrial units, and domestic workshops alike. By blending rigid structural support with dense, flexible bristles, this brush strip creates a long lasting defence along gaps where traditional solid seals often fail or bind.
Manufactured to rigorous standards, this 3 metre strip combines an extruded aluminium carrier with tightly packed Type 6 nylon filaments held securely inside an electro galvanised steel spine. Whether you need to seal the bottom edge of a warehouse pedestrian door, eliminate annoying rattles on a sliding partition, or prevent debris from entering sensitive machinery enclosures, this unit provides dependable performance across years of regular use.
At Doorfit, we understand that every entrance presents its own unique challenges, from uneven floor surfaces to extreme temperature swings. This profile has been engineered to handle these real world variations effortlessly, giving tradespeople and facilities managers a clean, professional finish that is straightforward to install and simple to trim to size.

Resilient Type 6 Nylon Bristles
The heart of this sealing strip lies in its dense cluster of extruded Type 6 nylon filaments. Nylon 6 is renowned throughout engineering and construction industries for its outstanding memory. Unlike cheaper synthetic fibres that bend permanently when compressed, these bristles spring back to their original vertical position every time a door opens or closes.
This resilience ensures a continuous barrier against outside airflow, dust ingress, and unwanted light leakage over a long operating life. Even when installed in high traffic corridors or exterior loading bay personnel doors, the bristles retain their shape without splaying out or tangling, maintaining consistent perimeter contact year after year.
Robust Metal Backing and Core
The individual nylon fibres are firmly locked into place using an electro galvanised steel core wire and protective steel channel. This multi layered mechanical lock prevents individual strands from pulling free under physical friction or continuous rubbing against threshold plates.
By treating the backing with an electro galvanised layer, the internal metal elements gain impressive defence against surface oxidation and corrosion. This protection remains vital when fitting the seal along external thresholds or in humid utility environments where moisture and condensation are commonly found.
Mill Finish Extruded Aluminium Carrier
Housing the brush strip is a sturdy 16mm deep extruded aluminium carrier supplied in a classic mill finish. The flat upright 180 degree mounting profile ensures the carrier sits flush against timber, steel, composite, or masonry surfaces. Its rigid backplate eliminates wavy distortions along the full 3 metre length, providing an attractive, professional border along the edge of your installation.
Mill finish aluminium offers natural corrosion resistance and blends smoothly with modern industrial fixtures. If your project demands a matching colour scheme, the untreated surface can also be prepped, primed, and painted to harmonise with bespoke joinery or brand aesthetics. The clean profile keeps screw fixings neat and ensures clear access during regular site maintenance.
The generous 3 metre carrier length provides ample material to tackle oversized openings without needing unsightly mid span joints. Whether you are outfitting large commercial double doors, expansive workshop sliders, or continuous perimeter partitions, a single uncut strip delivers seamless protection and tidy visuals.
Versatile Applications for Every Setting
While frequently chosen as a door draught excluder, this upright brush strip carrier 180 solves numerous everyday mechanical and architectural problems. Its fine, dense bristles conform effortlessly around textured or uneven surfaces where solid rubber gaskets would catch, bind, or leave substantial gaps.
- Thermal and Draught Exclusion Fitting the brush along the bottom and jambs of exterior doors significantly reduces cold air infiltration, supporting indoor temperature stability and easing heating loads.
- Dust and Light Sealing In cleanrooms, server suites, photography studios, and archives, the thick brush barrier blocks light seepage and catches airborne dust particles before they enter protected zones.
- Acoustic and Vibration Damping Mechanical vibrations often produce persistent rattling in loose fitting cabinet doors and sliding partitions. The continuous nylon brush absorbs vibrations and cushions contact points.
- Industrial Retainers and Guides Fitted along conveyor runs, manufacturing assembly stations, or machine enclosures, the flexible bristles act as soft touch guides that position delicate items without scratching them.
- Pest Deterrence By closing off perimeter gaps down to floor level, the tough nylon filaments deter crawling insects and pests from passing beneath storeroom doors.
Because the bristles slide smoothly across concrete, timber, linoleum, and industrial screed, door operation remains light and unhindered. This ensures you never have to force a door open or worry about dragging heavy rubber across premium flooring.
Engineered for Harsh Working Environments
Environmental extremes can quickly degrade inferior draught excluders. Low cost PVC strips often turn brittle in freezing winter weather and snap under light impact, while cheap rubber seals soften, warp, and stick when exposed to high ambient heat. The FS1/12 12mm Brush Draught Excluder 3M Length Aluminium Carrier has been engineered to operate smoothly across an expansive working temperature range from minus 40 degrees Celsius up to plus 100 degrees Celsius.
This extraordinary thermal tolerance means you can deploy the seal inside walk in cold stores, industrial freezer facilities, external loading docks, or warm boiler rooms without fear of structural deterioration. The Type 6 nylon fibres maintain their natural springiness in sub zero conditions, and the aluminium carrier will not buckle or deform under harsh afternoon sun.
Furthermore, the combination of aluminium, galvanised steel, and synthetic nylon provides reliable resistance against common industrial lubricants, light chemical splashes, and standard cleaning detergents. This robust build makes routine site hygiene maintenance quick and worry free.
Straightforward Installation and Sizing Guide
Achieving a perfect fit on your project is simple because this product can be cut to size using basic workshop tools. Follow these practical steps for a quick, neat result
- Measure the width of the door or frame opening accurately where the seal will sit.
- Slide the internal brush strip slightly out from the aluminium carrier channel.
- Cut the aluminium carrier to the required length using a standard fine tooth hacksaw.
- Cut the steel spine of the brush strip using heavy duty side cutters or a hacksaw. Squeeze the metal channel ends with pliers to clamp the outer bristles firmly in place.
- Slide the brush strip back inside the aluminium carrier until flush.
- Drill pilot fixing holes along the aluminium carrier face and secure the unit to your door or frame using suitable countersunk screws.
If you encounter minor high spots on uneven floors, the brush can be trimmed easily with sharp shears to contour around specific rises, guaranteeing smooth clearance without binding.
