Acoustic Door Seals

I need to achieve the highest acoustic rating possible on a standard door, can you help?  

Our recommended acoustic seals will certainly help you get the best acoustic performance possible from the door assembly you have - but it's important to remember that no sealing system will improve the acoustic performance of the door leaf itself. Every door leaf will have a maximum acoustic performance, which will have been determined by testing the door construction with all the gaps around the edges filled (caulked). Many combinations of our seals have been proven to maintain a door leaf's acoustic performance to the same level as if the gaps were filled, and that's the best acoustic performance you will be able to achieve.

Some of our recommended solutions are as follows - please click on the links to product page links for more information:

  • For fire rated doors, our DS or Finesse™ combined acoustic, smoke and fire seals - the complete solution in one seal. Both the DS and Finesse™ have been proven to achieve an acoustic performance of 31dB Rw on a standard architectural solid door core, when tested in conjunction with a Lorient LAS8001 automatic threshold seal.
  • For non-fire rated doors, we would always recommend our Batwing® acoustic and smoke seal. It has also achieved 31dB Rw on a standard architectural solid door core, when tested in conjunction with a Lorient LAS8001 automatic threshold seal.

Do remember it is essential to fit a threshold seal to complete the system. You may find it helpful to read our FAQ on threshold sealing.

To find out more about our recommended acoustic solutions, please refer to our Acoustic Sealing Systems manual, available to download from this website. This also contains more information about how doors are tested, and the acoustic performance of various types of standard door construction.

We also offer a CPD seminar, entitled “Performance Door Design: The Basics of Sound Reduction”. Please visit our CPD Seminars page for more information.
