Aquamac 21 Door Seal
Aquamac 21 is a black Q-Lon weather seal (Schlegel AQ21) that keeps doors sealing tight. Made from durable polyurethane foam, it pushes into a kerf groove in the door edge or frame and compresses gently as the door closes — cutting draughts, moisture, dust and noise without perishing over time.
It seals a gap of 4.0–7.5mm and trims easily to length. Each roll is 5.5 metres, enough for a standard single door, and the discreet black (RAL 9005) finish blends with most doors and frames.
- Black Q-Lon polyurethane-foam seal (RAL 9005)
- Kerf-fit — pushes into a ~3mm groove, no adhesive
- Seals a 4.0–7.5mm gap
- Reduces draughts, moisture, dust and noise
- 5.5m roll, trims to length
