Quiet Door™ Automatic Door Sweep

Quiet Door™ Automatic Door Sweeps reduce noise transfer through doors by forming a tight fit against the threshold of a door. This product can be installed on new doors with cheap vinyl sweeps, or to existing doors with old, worn-out sweeps. Our automatic sweeps can be installed on wood and metal doors. Quiet Door™ Automatic Sweeps are made of heavy duty aluminum, long lasting silicone seals and include all stainless steel hardware. Silicone seals remain flexible in a variety of temperatures and resist tears better then the less durable, widely available vinyl and foam seals. Quiet Door™ Automatic Door Sweeps are automatic, meaning, that as the door closes the seal is pushed snuggly to the threshold. As the seal materials age, the spring action pushes the seal snuggly to the threshold to reestablish a like new fit. Our automatic door sweeps will decrease air flow, increasing the thermal performance of any door.

Tight Fitting Automatic Door Sweeps With Acoustic Tested Quality

When you close your door, you expect the entrance to your room to be snuggly and efficiently shut. Unfortunately, this is not always the case, as many doors leave openings even when closed entirely. Our line of automatic soundproof door sweeps provides a form-fitting tight seal against the threshold of your door, ensuring no noise gets in while guaranteeing sound from within is kept from getting out.

Quiet Door™ sweeps are automatic as well, which means they perform their job without any effort required on your end. Simply shut the door, and your automatic soundproof door sweep seal will take care of the rest!

The Soundproofing Quality Your Room Deserves

Our line of soundproof materials is engineered with endurance, strength, and high performance to guarantee our customers receive the noise and reverberation reduction they need. Tell us about your room, and we’ll help you find the right products crafted for you.

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.

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
