Quiet Door™ Perimeter Seal

Quiet Door™ Perimeter Seals form a tight fit around a door to help you reduce sound transfer and enjoy greater peace and quiet. You can install these durable perimeter seals on existing doors with worn-out seals or new doors with cheap seals made of foam or vinyl.

Quiet Door™ Perimeter Seals offer long-lasting soundproofing capabilities for metal and wood doors, providing superior acoustic performance as they withstand various temperatures and resist tears. The seals can be readjusted to ensure a continual seal as the material wears. Simply loosen the mounting hardware and reestablish the snug fit.

These door perimeter seals offer exceptional performance due to their:

  • • Heavy-duty aluminum framing
  • • Durable silicone seals
  • • All stainless steel hardware

Quiet Door™ Perimeter Seals can also decrease airflow, allowing you to increase your door’s thermal performance and energy efficiency.

When you need to upgrade your door’s seal for better sound control, choose Quiet Door™ Perimeter Seal. Order your perimeter seal today!

Soundproofing seals and sweeps are tested with operational doors. Operational meaning they open and close like a door should. Then, a separate test is completed on a “static door”, a door that is non operational. The static door will have a higher Sound Transmission Class (STC) number due to the lack of air gaps. When a door is hung the soundproofing performance plummets because of the additional air spaces. Compare the static door rating to the operational door rating. The smaller the difference in STC rating, the better the perimeter seals and sweeps will reduce noise transfer.

All of our Quiet Door™ Soundproofing products were tested as assemblies and not single products. Our tests included perimeter seals, doors sweeps and thresholds. For help in choosing an assembly or single product for your situation, please give our friendly consultants a call at 1-866-949-9269.

Some pre-drilling is required.

The times I talked with you on the telephone and corresponded through email you have been very helpful and efficient. I would highly recommend Soundproofcow.com to anyone!

– S. Cimino, PA

I have emailed a lot of different manufactures and I have to say your customer service is head and shoulders above all of them. I emailed your company at about 9pm my time and when I woke up the next morning you had already answered my question and then the follow up was a few hours later. I am impressed. Thanks a lot for the quick turn around!

– E. Gustafson, NV

I just wanted to send a quick thank you for your rapid response and helpfulness. I very much appreciated it. You have been responsive in every way all through the process. It has been a pleasure doing business with you and your company.

– T. Alexander, CA

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.

– Mike
