Sealing Door from noise and weather

How To Stop Noise Getting Past Doors

Door Seals of Australia have a range of automatic door bottom seals created to block what is often the largest gap around a door – the gap between the door and the floor. Filling the gap when the door is closed, automatic seals keep out dust and insects and protect from air, water, smoke, wind, light and noise to guarantee comfort and safety in living spaces.

Door Bottom Seal

The seal operates by a plunger compressing against the door frame when the door is fully closed, which activates an internal seal profile to project downwards by up to 14mm. The plunger releases upon the door opening to retract the seal completely, hidden from view.

These DSA seals have been designed to be the most compact available and do not require the fitting of endplates when fully recessed in the door bottom. Installation can be either surface mounted, semi-recessed of fully recessed. DSA have a range of accessories to make the door bottom seal fully airtight with an acoustic rating up to 51dB for the seal. Lengths are available up to 1800mm – which is ideal for wider doors being more commonly specified.

If you specify the inclusion of DSA perimeter and automatic door bottom seals for your next project, this system can make doors fully airtight to resist noise whether they be single and double door situations.
