Udderly Quiet™ Acoustic Panel – 200 Series


The 200 Series — part of the Udderly Quiet™ family of products — is a general-purpose, modular soundproofing panel that offers flexibility and performance at an affordable price point. It’s one of our best-selling products, and an excellent choice for everything from recording studio and rehearsal space use to more general soundproofing applications.

200 Series panels feature a glass mineral wool core and fabric covering. Glass mineral wool offers excellent noise reduction and low weight, allowing for a variety of installation options. For additional protection, panel edges are dipped in a special resin hardener that increases their strength. As a result, 200 Series products are some of the most durable all-purpose acoustic panels on the market today.

Product Options

The popularity of our 200 Series all-purpose acoustic panels is due in part to the extensive customization options we offer. Panels are available in 1” or 2” thicknesses, with square, beveled, mitered or rounded edges, and in any of more than 1,000 fabric options. Standard sizes range up to 4’ by 10’, though large format panels are available by special request.

Installation Made Easy

200 Series panels can be installed with magnets, Z-clips or Velcro, or with a special adhesive to fix them in place permanently. We can help you determine the optimal number and best placement of 200 Series panels for any room.

Adhesive Panel Mounting Adhesive mounting is ideally suited for permanent applications requiring speed and ease of installation. This type of installation requires little to no layout time depending on various field conditions. Use this method if there is a potential for impact or other stresses. The adhesive method provides the strongest bond between panel and wall.


Z-clip Panel Mounting Z-clip mounting is ideal for applications where frequent panel removal & re-hanging is required. This type of installation demands careful planning and layout before the panels are placed on the wall. This type of mounting method will not support more weight than the panel itself. Panels mounted with Z-clips cannot be subjected to peel away stress as this may cause a failure of panel to Z-clip bond.

What exactly is the 200 Series Udderly Quiet™ Acoustic Panel?

The Udderly Quiet™ 200 series Acoustic Panel consists of an Acoustical Glass Mineral Wool core wrapped in an Acoustic Fabric. The edges of this Acoustic Panel are dipped in a resin hardener to protect the edges, add strength and increase the life of the Acoustic Panel.

What is an Acoustic Fabric and what are my options?

An Acoustic Fabric is a fabric that is considered acoustically transparent. All Acoustic Fabrics have whats called an “Open Weave” which allows sound to travel through the fabric material and into the sound absorbent core. There are 1000’s of Acoustic Fabric Options.

Do I have to use one of your fabrics or can I provide my own?

These are your panels! We will wrap them in whatever fabric you choose. All we ask is that you send us a 36 inch x 36 inch sample of fabric so we can test it out. We want to make sure the adhesive bonds the materials properly and also make sure the adhesive doesn’t “bleed” through the fabric and create spots on the face of the panel.

How Big can I get the 200 Series Acoustic Panels?

The largest we can construct a seamless 200 Series Acoustic Panel is up to 4 ft. x 10 ft. For Larger Acoustic Panels, check out the 250 Series and the 350 Series. Those models have Aluminum Frames which allows for larger panel construction.

What Shapes are available with the 200 Series Acoustic Panels?

These panels are totally customizable. We can make anything from rectangles to circles to free-form shapes. Some of our clients have provided patterns of modular designs. Check out our Udderly Quiet™ Acoustic Panels Gallery for some creative ways to use these Acoustic Panels.

What are the Most Economical sizes for Acoustic Panels?

Any Panel where one of the dimensions is 4 foot. 2 ft. x 4 ft., 4 ft. x 4 ft., 4 ft. x 5 ft., 4 ft x 8 ft. and 4 ft. x 10 ft. are the most popular and economical sizes for Acoustic Panels.

What Edge Profiles are available for the 200 Series Acoustic Panels?

We offer these panels with Square, Beveled, Mitred and Rounded edges. The Square and Beveled Profiles are by far the most popular.

How Many Acoustic Panels do I need?

We use Proprietary Acoustic Software and information from you about your space to answer this question. We use three main criteria to determine how much acoustic material is needed. First, we need to know the Dimensions (Length, Width and Height) of the Room or Space that is being treated. Typically, the larger the space the more Acoustic Panels are needed to drop the reverb time to a preferred level.

Second, we need to know the existing Wall, Ceiling and Floor construction materials. All Construction materials like Drywall, Concrete, Brick, Metal, Wood and Carpet have industry accepted inherent Acoustic Values that affect the acoustics of the space. We know these values and use them to help determine how much Acoustic Material is needed to get the desired results.

Third, we need to know How the Space is being used or the function of the space. The use of the space greatly affects the amount of absorption materials needed to achieve the desired results. Different spaces require different reverberation times. For example, A Recording Studio requires a much lower reverb time than an Office environment. A Restaurant requires a different reverb time than a Home Theater. We know the Industry accepted reverb times for a multitude of spaces and use these times when determining the amount of acoustic coverage.

I was little bit overwhelmed in figuring out how to get rid of the echo in our conference room. I called in to find out about what I needed to do. Drew was so helpful from the start when we established how much material I would need to when the panels arrived and we had installation questions. I looked around and found that the panels were a little bit more expensive through Soundproof Cow, but the help and service we had throughout was well worth the higher cost. I will immediately come back if there is ever a need for panels again.
I McCoy, NY

I saw panels cheaper than the ones I bought from Soundproof Cow, but after speaking with Jim and how helpful he was in figuring out what size panels would work in our area and walking me through from start to finish, I wouldn’t look anywhere else.
Jared Tolsen

Panels got the job done. My buddy is having the same issue in his office’s conference room so I gave him all the info on Soundproof Cow. Talked to him last night and said he called in, got an estimate, and is placing his order first thing tomorrow.
