Effective door sealing for comfort and energy efficiency

Doors without seals allow drafts, cold, and noise to enter living and working spaces. The gap between the door leaf and the floor becomes an entry point for undesired influences and drives up heating costs. The problem is exacerbated with exterior doors: driving rain penetrates, sound insulation is lacking, and energy efficiency suffers. Traditional solutions such as thresholds provide sealing, but prevent barrier-free access.

Planet drop-down seals from ASSA ABLOY (Schweiz) AG provide a remedy: they automatically seal the door gap when the door closes and combine energy efficiency with sound insulation – without structural barriers. The drop-down seals are suitable for new buildings and renovations – from wooden, metal, and PVC doors to glazed doors. For exterior doors, Planet X3 and zero thresholds offer threshold-free construction at the main entrance – the most important entrance for accessible buildings.
