Installation Step-by-Step Instructions


Quiet Door™ Perimeter Seals reduce sound transfer through doors by forming a tight fit around the perimeter of new doors with cheap seals, or existing doors, with old worn-out seals. These seals can be used on wood and metal doors. Quiet Door™ Perimeter Seals are made of heavy duty aluminum framing, long lasting silicone or neoprene seals and include all stainless steel hardware. The soundproofing capability of the Quiet Door™ Perimeter Seals last due to the seal quality. Silicone is durable, long lasting seal material and has superior acoustic performance. Silicone seals remain flexible in a variety of temperatures and resist tears better than the less durable, widely available vinyl and foam seals. Quiet Door™ Perimeter Seals can be adjusted to keep fit snug. As the seal material wears, loosen the mounting screws and reestablish the fit against the door. Our Quiet Door™ Perimeter Seals will decrease air flow, increasing the thermal performance of any door.

Acoustic Data

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.

Cautions and Limitations

The Quiet Door™ line of perimeter seals and sweeps can be used on almost any door to reduce sound transfer and they can be used on almost any door type. Some older doors may not have enough mounting area. Please double check all measurements and dimensions.

For doors with overhead closers, install seals before the closer. Seals installed at head will require the closer body be installed 1/4” lower on the door.

The Quiet Door™ line of perimeter seals and sweeps may need to be trimmed to fit. When trimming our Adjustable or Automatic products, care should be taken to not cut internal mechanisms that could impact the functionality of the product.

Some pre-drilling is required.

Quiet Door Install

I can’t complain when things are cheap and work really well. I would use this again in an instant.

I wasn’t looking to spend a whole lot of money for my apartment door, so I saw you guys had two types of seals, the adjustable one and the one that I bought. What a good bargain, it works great.
