Door Seal

A slimline, mortised automatic drop seal. It features a high efficiency mechanism, which lifts the seal clear of the floor as soon as the door is opened by a few millimetres resulting in lower door operating forces. Requires no power connection. Self-levelling on uneven floors; seal height can be adjusted independently of fixing screws. Can be fitted to aluminum doors by door fabricators.

Door Bottom Seal is a weatherproofing and soundproofing solution designed to seal the gap at the bottom of wooden doors. Made from durable materials like rubber or silicone, it prevents drafts, dust, noise, and moisture from entering through the door gap. Ideal for improving energy efficiency and reducing sound transmission in offices, homes, or commercial spaces, it helps maintain temperature control and enhances privacy.
