Draught Excluders

For the Trade

Start with how much movement the opening sees and how hard the seal has to work. On a door that gets regular use, you usually want something that keeps contact without dragging, because the call-back is often a seal that’s too tight or too light for the gap. Brush draught excluders suit uneven thresholds and a bit of wear. Foam and rubber options work better when the face to seal is more consistent. Self adhesive draught excluders are quick to fit, but the bond and the surface prep matter more than people think. Pick the one that matches the opening, not just the cheapest strip on the shelf.

Popular Draught Excluder Formats

If the gap is even, self adhesive draught excluders are the quickest fit. They keep the job simple, but they need a sound surface. They are not the best choice for rough or tired frames.

Brush draught excluders suit doors that drag or gaps that vary. The bristles keep working without binding, though the seal is looser than a compressible strip.

Foam draught excluders are the low-cost option for steady, even gaps. U shaped draught excluders give you a neat push-on fit with less fuss, while window draught excluders are the separate pick for sashes rather than doors. If you are matching the rest of the job out of Ironmongery, that usually narrows it down fast.

Key Differences When Choosing

Material is usually the first call. Rubber draught excluders give a firmer seal and cope better on openings that get regular use, but they are less forgiving to fit than foam and feel stiffer on the job.

Foam draught excluders are cheaper and quicker to handle, though they tend to wear sooner on busy doors. Self adhesive draught excluders save time where the surface is clean and consistent, but once the backing is down you have little room to correct it.

For external openings, Outdoor Hardware is often bought at the same time. For sashes and other openings with moving parts, Window Furniture usually comes into the spec as well.

Next Decisions After Choosing

Once you’ve picked the seal, the next call is what sits around it. On a door job, that usually means checking the threshold, any panel or screen detail, and whether the frame finish needs tidying after the old strip comes off.

On windows, you’re often looking at the sash hardware and the condition of the surrounding finish at the same time. A worn edge or loose fitting can make a good seal look poor. If the opening’s already being worked on, sort the other bits now rather than come back for one small item.
