Nylon Brushstrip Draught Excluder 2m | Aluminium Door Brush Seal Strip UK

Vertical Brushstrip Draught Excluder — Aluminium Channel with Nylon Brush

Our Nylon Brushstrip Draught Excluder provides an effective, durable seal for gaps around doors, preventing draughts, dust, insects, and noise from passing through the gap between door and frame. The aluminium fixing channel gives the product structural rigidity while the nylon brush pile creates a flexible, compressible seal that accommodates slight door movement and misalignment.

Available in multiple brush pile depths (10mm, 12mm, 15mm) to suit different door gaps. Supplied in 2m lengths that can be cut to the required height. Suitable for interior and exterior doors in residential and commercial applications across the UK.

Selecting the Right Brush Depth

Measure the gap between your door and the door frame or threshold surface:

10mm brush: Gaps of approximately 7–10mm
12mm brush: Gaps of approximately 9–12mm
15mm brush: Gaps of approximately 12–17mm

The brush should contact the opposing surface with light compression — too much compression impedes door operation; too little contact reduces sealing effectiveness.

Applications

Residential entrance doors — Draught and heat loss prevention at exterior doors
Internal fire doors — Smoke and draught seal where intumescent strip is also fitted
Commercial offices and retail — Dust and insect control at service doors
Agricultural and industrial buildings — Pest and draught exclusion at large openings
Garage doors — Side-gap sealing where roller or sectional doors meet the frame

Frequently Asked Questions

How do I cut the brushstrip to length?

Cut using a fine-tooth hacksaw or tin snips. The aluminium channel cuts cleanly; tape the pile aside to avoid catching it in the cut. Deburr any sharp edges with a file before installation.

Can this be used as a bottom door seal?

This is a vertical (side and top frame) brushstrip. For bottom-of-door sealing, a door bottom seal or threshold strip is more appropriate — these are designed for horizontal installation against the floor surface.

Is this brushstrip suitable for exterior use?

Yes — the aluminium channel is corrosion-resistant and the nylon brush is weather-resistant. UV exposure will not significantly degrade nylon pile in the timeframes relevant to residential use.
