About this door bottom seals & brush strips
Foam and rubber seals rely on being squeezed. If the gap varies along its length, a seal that is perfect at one end is too tight at the other. A brush strip handles this much better: the bristles bend as they brush against the surface, so they cope with gaps that run narrow to wide.
This Joaercs strip is 5 metres long, 9mm wide and 9mm thick, with a soft pile and a self-adhesive backing. It suits gaps of about 4mm to 8mm and is designed for doors, windows and patio doors. It is particularly useful on sliding windows and sliding doors, where a compressible seal would catch on the moving part.
Fit it to the frame, not the sash, with the bristles facing the moving surface. Clean and dry the frame, peel a short length of backing, press and move along. Colour is a matter of taste: this listing is white and the supplier also sells grey and black.

The complete guide
Sliding parts need a seal that does not grab. Brush bristles slide past each other without stiction.
Fit to the fixed part of the frame, with the brush pointing at the moving part. Keep the tracks clean.
Cut with sharp scissors and butt the ends tight. A tiny gap at the corner will leak, so press the strip into the corner.
