MMT Acoustix® Door Seals

Soundproofing Door Seals

Sound leaks through gaps far more readily than through the door leaf itself. Three seals close the threshold and the frame: a metal bottom seal, a silicone bottom seal and an EPDM perimeter seal. Made by MMTPL at the Palwal plant, Haryana.

Soundproofing: the fix for every sound problem

3-layer soundproofing

  1. 1

    Layer 1: SoundBlanket® MLV

    The dense barrier that isolates sound and stops it passing through walls, ceilings and floors.

  2. 2

    Layer 2: BassBloc®

    High-density sound absorber over the MLV that controls low-frequency noise.

  3. 3

    Layer 3: Echsorbix®, SoundaXe® or WDWL®

    The final acoustic finish: Echsorbix® PET felt, SoundaXe® wooden acoustics or WDWL® wood wool panels.

Layer 2 can also be covered with gypsum or cement board before adding the final acoustic layer.

Different thickness in each layer will give different STC and NRC levels.

FAQs

Questions about door seals

Who manufactures these door seals in India?
MMTPL (Mahabir Multi Tech Private Limited) manufactures them at its Palwal plant in Haryana, India, and supplies them in India and 25+ export markets.
Why seal the threshold and perimeter?
Sound leaks through gaps far more readily than through the door leaf itself. A 1% open area in a partition can cut its effective performance by more than half, which is why sealing the perimeter and threshold usually does more than upgrading the door.
What gap can the metal bottom door seal close?
Up to 20 mm. The seal measures 900 x 35 x 35 mm and is trimmed to the door width on site.
What is the metal bottom door seal made of?
Carbon metal with a rubber insulation strip, finished in brown.
How is the metal bottom door seal fitted?
Screw mounted to the bottom of the door leaf.
What size door does the silicone door seal fit?
Standard doors up to 3 ft wide. The seal is 920 mm long and 15 mm wide.
What is the silicone door seal made of?
Silicone with a concealed metal spine, which keeps the seal straight while letting the silicone flex to an uneven floor.
How is the silicone door seal fitted?
Self-adhesive, onto a clean dry door bottom.
What is EPDM and why use it?
Ethylene propylene diene monomer rubber. It resists UV, ozone and temperature swings and keeps its elasticity for years, which matters on a seal that is compressed and released every time a door moves.
What size is the EPDM perimeter seal?
6 mm wide by 6 mm thick, in a D-profile, on a 6 m roll that splits into two separate seals.
How is the EPDM perimeter seal fitted?
Self-adhesive onto the door or window frame rebate.
