Description
Professional Draught and Environmental Protection with the FS4/26 Brush Strip
Uncontrolled gaps beneath doors, around industrial gates, and along automated entrance systems can cause continuous problems for property owners and facilities teams. Large clearance margins allow cold air to rush inside, pushing heating systems to their limits and running up expensive winter energy costs. At the same time, wide perimeter gaps invite windblown dust, road debris, rain spray, light infiltration, and unwanted pests. Without a resilient physical seal in place, high traffic doors also tend to vibrate, chatter in their tracks, and rattle whenever outdoor wind conditions change.
The FS4/26 26mm Brush Draught Excluder 3M Length Aluminium Carrier provides an adaptable, heavy duty solution for residential, commercial, and light industrial entryways. Built with an extruded mill finish aluminium carrier and an electro galvanised steel spine, this high specification brush strip system bridges difficult gaps of up to 26mm. It deflects exterior air currents, buffers mechanical movement, and keeps work areas clean, quiet, and comfortable throughout the year.
Whether you manage a busy warehouse loading bay, maintain commercial retail units, or want to draughtproof large bespoke timber doors, this generous 3 metre profile gives you complete coverage in a single piece. The system provides immediate protection across expansive thresholds and can be tailored quickly on site to fit non standard openings.
Core Engineering and Performance Features
High Resilience Type 6 Nylon Filaments
The core of this draught excluder features dense type 6 nylon bristles that are specifically engineered for excellent mechanical recovery. Unlike low quality polypropylene filaments that crush flat, snap, or become permanently distorted under everyday friction, nylon bristles bend smoothly against moving thresholds and immediately bounce back to their upright stance. This outstanding memory ensures that your seal stays thick and uninterrupted for years, even across uneven floorboards, brushed concrete, or tiled surfaces.
Wide Operating Temperature Range
External entrance hardware must cope with demanding weather shifts without cracking or losing flexibility. The nylon filaments in this assembly remain stable across an impressive working temperature range from -40 degrees Celsius right up to +100 degrees Celsius. This broad tolerance means the seal will not become brittle in freezing winter conditions, nor will it soften or splay out during direct summer heat exposure, giving you dependable draught protection in any climate.
Rigid Mill Finish Aluminium Carrier
The upright 180 degree mill finish aluminium carrier provides a stiff, reliable foundation that holds the entire assembly true along its full 3 metre length. The carrier profile has a depth of 29mm, giving you ample flat surface area for clean fixing into timber, steel, or composite frames. The clean metallic finish looks smart in industrial and commercial environments, or it can be degreased and painted on site to match existing woodwork and surround finishes.
Electro Galvanised Steel Core Assembly
Bristle density and longevity depend entirely on the strength of the internal spine. The FS4/26 utilizes an electro galvanised steel core wire and metal backing channel to clamp the folded nylon filaments securely under pressure. This galvanised steel construction offers great resistance to atmospheric moisture and corrosion, keeping the bristle density uniform and preventing individual strands from shedding during rigorous operational movement.
Installation and Customisation Pipeline
Stage 1: Dimension Measurement and Gap Assessment
Accurately measure the door or aperture width along with the vertical floor clearance. Ensure the 26mm bristle projection comfortably spans the gap with a light sweep against the floor, rather than heavily compressing flat, to maximise seal efficiency and bristle life.
Stage 2: Carrier Trimming and Core Separation
Slide the galvanised brush core out of the aluminium holder before cutting. Measure and trim the aluminium carrier with a fine tooth hacksaw. Cut the internal metal backing strip separately using heavy duty wire cutters or a cutting disc, leaving a clean end profile.
Stage 3: End Crimping and Bristle Maintenance
Lightly squeeze or crimp both ends of the galvanised steel core channel with pliers to lock the edge bristles permanently in place. Reinsert the brush assembly into the aluminium housing, ensuring both components line up neatly with no loose filaments.
Stage 4: Structural Fastening and Final Alignment
Pre drill pilot holes through the 29mm aluminium carrier face at even intervals. Position the strip straight against the bottom or vertical edge of your door, insert your chosen fixings, and check the sweep movement to ensure smooth operation across the doorway.
Versatile Applications for Commercial and Domestic Properties
The upright 180 degree profile configuration of the FS4/26 26mm Brush Draught Excluder 3M Length Aluminium Carrier makes it one of the most flexible sealing strips available on the market. Unlike angled brush profiles that are restricted to specific jamb positions, an upright carrier fastens flush to flat surfaces, opening up a wide variety of installation scenarios across industrial properties, storage facilities, workshops, and family homes.
- Industrial Roller Shutters and Sectional Doors: Seals irregular ground contact points, preventing leaves, wet weather, and outside dirt from blowing into clean storage areas.
- Sliding Gates and Security Enclosures: Acts as a durable, non-scratching guide that cushions travel and reduces tracking rattle under high wind loads.
- Revolving and Automated Entrance Doors: Provides a soft perimeter barrier that seals against drafts without catching or loading down drive motors.
- Retail Loading Bays and Service Doors: Bridges wide gaps beneath heavily used personnel and supply doors to maintain stable internal temperatures.
- Acoustic and Light Reduction: Blocks light spill around darkrooms, photographic studios, and machinery housings while dampening airborne sound transfer.
- Rodent and Pest Exclusion: Closes off threshold gaps that mice, crawling insects, and other pests commonly use to enter buildings.
