Description
Professional Draught and Environmental Protection with the FS5/80 Seal
Large perimeter openings beneath industrial shutters, warehouse loading bays, and commercial entrance doors are often a primary source of building heat loss. When exterior doors sit unevenly above concrete slabs or wear grooves into hard surfaces over time, standard rubber sweeps can quickly tear, split, or buckle under friction. This leaves wide voids that let cold air rush inside, increasing internal heating demands and driving up energy expenditure across commercial facilities. In addition to thermal losses, unsealed floor thresholds permit swirling exterior debris, road dust, surface water splash, and insect pests to penetrate internal storage bays and sensitive processing environments.
The FS5/80 80mm Brush Draught Excluder 3M Length Aluminium Carrier resolves these persistent structural problems through an adaptable, heavy-duty physical barrier. Featuring a deep 80mm bristle projection housed inside a sturdy 33mm extruded mill finish aluminium carrier, this sealing system bridges substantial gaps where traditional weather seals fail. The flexible bristles contour seamlessly across uneven screeds, rough flagstones, and threshold plates without jamming door movements or causing motor drag on automated sliding gates. By maintaining contact across irregular surfaces, the brush barrier buffers high winds, deadens mechanical rattling, and protects indoor working conditions throughout the year.
Designed for dependable service in demanding settings, every component of the FS5/80 assembly is built to withstand rigorous physical wear and wide temperature variations. Dense filament packing prevents draughts while allowing the bristles to deflect smoothly during door operation, returning upright every time thanks to the excellent mechanical memory of Type 6 nylon. Whether you are outfitting a busy distribution hub, upgrading plant rooms, or improving weather protection around agricultural workshops, this complete three-metre unit provides a resilient, low-maintenance sealing solution that installs cleanly onto almost any flat door face.
Key Performance Advantages
Deep Floor Gap Bridging
The generous 80mm brush projection effortlessly spans oversized thresholds and ground clearance issues where conventional threshold plates fall short, blocking high-velocity winds without impeding door travel.
Resilient Nylon Memory
Manufactured from high-grade Type 6 nylon filaments, the bristles absorb repeated mechanical compression and recover their upright shape without splaying, breaking, or taking on permanent structural bends.
Rigid Aluminium Carrier
A heavy-duty 33mm extruded mill finish aluminium profile holds the steel-spined brush securely in place, resisting impact flex and providing a stable mounting surface along the full three-metre length.
All-Weather Capability
Featuring an operating thermal range from minus 40 degrees Celsius up to plus 100 degrees Celsius, the seal remains fully flexible through freezing winter frosts and intense direct summer heat.
Installation and Sizing Guide
Step 1. Measure and Align
Measure the overall door leaf or frame width carefully. Position the aluminium carrier along the base to ensure the 80mm bristles lightly sweep the highest floor point across the entire door opening arc.
Step 2. Cut Carrier Profile
Slide the inner steel brush core out of the carrier casing. Mark your finished length and trim the aluminium housing cleanly using a standard metal hacksaw, smoothing away any rough cut edges.
Step 3. Trim Brush Insert
Trim the nylon filaments with heavy shears and cut the electro-galvanised steel backing with wire cutters. Crimp the cut metal end lightly to lock the internal wire core before sliding it back into place.
Step 4. Fasten to Substrate
Drill fixing holes through the aluminium flange at regular intervals. Affix the assembled strip firmly to timber, steel, or masonry door leaves using appropriate counter-sunk screws or self-tapping fixings.

Frequently Asked Questions
Can this brush strip be shortened to suit narrower doors?
Yes, both the aluminium profile and the brush insert can be cut to fit your exact door width. You can easily cut the mill finish aluminium carrier using an ordinary hacksaw. For the brush insert, trim the bristles with heavy scissors or side cutters, and cut the electro-galvanised steel backing channel with wire cutters. We suggest gently pinching the cut steel ends with pliers to keep the core wire firmly in place.
What makes Type 6 nylon filaments superior to cheaper polypropylene brushes?
Type 6 nylon offers superior flexural recovery and durability compared to standard plastic fibres. When subjected to continuous friction, dragging over rough surfaces, or temporary crushing, nylon filaments spring back straight without breaking or bending out of shape. They also remain pliable in freezing weather, whereas cheaper polypropylene fibres often turn brittle and snap off when temperatures drop.
Does the brush strip help with noise and rattling doors?
Yes, installing this seal helps dampen vibrations significantly. In addition to stopping cold air and light infiltration, the high-density nylon bristles cushion heavy doors and shutter curtains against their frames and guides. This reduces mechanical rattling during gusty winds and provides a useful layer of perimeter acoustic deadening for commercial premises.
Can the FS5/80 be fitted to sliding doors and roller shutters?
It certainly can. The upright 180-degree carrier design works brilliantly along the bottom rail of roller shutter curtains, the base of sectional overhead panels, and the vertical leading edges of large commercial sliding gates. Because the bristles bend smoothly without excessive friction, they do not stall automated operators or scratch expensive floor coatings.
