Udderly Quiet™ Acoustic Panel – 300 Series


Looking for an impact-resistant acoustic panel that’s suitable for use in high-traffic areas? Look no further than the Udderly Quiet™ 300 Series. Taking the flexibility and superior soundproofing characteristics of our bestselling 200 Series, we’ve added a special impact-resistant layer for additional protection against dents and bumps.

Applications and Design Options

300 Series impact-resistant acoustic panels are a great choice for gyms, hallways and other areas where accidents are common. They mount firmly to any flat surface using Z-clips or our PL® Construction Adhesive. Like all our Udderly Quiet™ acoustic panels, they’re available in a practically limitless number of colors to meet any specific design or branding requirements your facility has.

We also give you the option of choosing square, beveled or rounded edges to give your panels a unique look.

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 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 300 Series Acoustic Panels?

The largest we can construct a seamless 300 Series Acoustic Panel is up to 4 ft. x 10 ft. For Larger Acoustic Panels, check out the 350 Series. Those models have Aluminum Frames which allows for larger panel construction.

What Shapes are available with the 300 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 300 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 Proprietory 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 just got some panels for the connecting hall way between the offices of my partner and me. There is always people talking in the hallway and it gets a little bit noisy. I’m kind of klutz when I’m walking so I tend to walk into things. With it being a fiberglass the standard panel would not be durable enough for my lumbering down the hall. For that reason we went with the 300 Soft Sound because it had a layer of impact resistance. It seems to be working pretty well. Just yesterday I was sending an email on my phone and smacked right into it. The panel held up fine and it was easy to find a color to match the paint we had used in the hallway.

As someone working in a museum it is very easy to say that sometimes people aren’t really paying attention to what they’re doing and where they’re walking. We have a great room where the sound was terrible and needed to put some soundproof paneling throughout to knock down some sound. We were a bit hesitant at first because we didn’t have the space to put them up high enough that people wouldn’t possibly bump against them. Saw the Impact Resistant panels and thought they would be perfect. I was right I’m proud to say. The noise is no longer an issue and I saw firsthand someone bump against it pretty hard without any damage to the panels. This turned out to be a great investment.
