ResoNix Sound Solutions Frequently Asked Questions

Frequently Asked Questions

When will my order ship?

       Most orders ship within 24 hours of the order being placed, excluding weekends. If you haven’t gotten an update since placing your order after 48 hours, the product you ordered may be on backorder. Product stock information is always available on each product page. Some people do tend to miss this when ordering though. If a product is on backorder at the time of your order, it will be shipped to you the moment we have it back in stock.

Do I get tracking information with my order?

       Normally, yes! Our system automatically sends tracking information. If you do not receive tracking info, please let us know asap. Sometimes we need to update our system and we can always send you the tracking info manually. 

       The unfortunate truth is that sometimes we experience issues with our website and our shipping software communicating, so sometimes tracking will not be received. If you did not receive tracking and you would like it, just shoot us an email and I can send it over.

Do you offer returns or exchanges?

       Yes we do! The only thing we require is that the product is not defiled in any way, and isn’t missing pieces. Meaning, if you order a box of 20 Mega CLD Squares, you must return the full box, or none of it will be returned. What we can do in some cases is offer it for sale as b-stock to those in our ResoNix Customer Support Group on Facebook, but it will not be a traditional return. Just shoot us an email, fill out our contact form, or give us a call and we can help you out. 

       For domestic orders in the continental US we will cover return shipping as well.

Your CLD Rectangles come with more square feet of product, but costs less than some of your other CLD products. Why?

       This is one of those questions that can be answered by reading the descriptions of each product. The ResoNix CLD Rectangles are a thinner version of  CLD that we offer. It is meant to compete in a price bracket that is typical of more commonly known products, but with ResoNix quality Butyl and Aluminum. The ResoNix CLD Rectanges are 45-mil thick butyl with a 3-mil aluminum constraining layer, while the ResoNix CLD Squares have 100-mil thick butyl and a 4-mil thick aluminum constraining layer. The ResoNix Super Pro Mega Max CLD Squares have a 100-mil thick butyl layer and a 12-mil thick aluminum constraining layer. Personally, if you can swing the barrier to entry price tag, the ResoNix CLD Squares are a better price-to-performance value than our ResoNix CLD Rectangles, which is why we didn’t stock them for a few years. But some people don’t need the very best for some projects, so they are back by popular demand. 

       PS. Mil is not short for millimeter. Mil is a unit of measurement that is one-thousandth of an inch. 

What products should I use and what method of installation should I use to treat my car doors, trunk, floor, etc?

       While every application is different, we do have a guide available showing you how WE treat our own and our in-person customer’s doors, and this is what we recommend for the very best performance. If you don’t need to go this far or you have a specific application, or if you just need clarification, feel free to reach out to us.

       Please note, we also have our Reference Information & Guide page which is FULL of information regarding automotive sound treatment. This article will answer pretty much any question you may have about treating a vehicle.

Should I use ResoNix Fiber Mat or ResoNix Barrier?

       First, BOTH can be used together, as they work differently and have different end results. you do not have to select one or the other. But, this isn’t an easy one to answer for everyone at once. Not because they are similar in performance, but because each customer’s situation is different. Different budgets, different vehicles, different levels and frequencies of noise, different sources of noise, different goals, and more. Not only that, but these two different products work differently and are effective for different reasons as well. I suggest reading our Reference Information & Guide page to become familiar with Sound Absorbers and Noise Barriers to understand the difference and figure out what is right for you. If you still need help, you can always reach out to us and we can guide you.  

Should I use ResoNix Fiber Mat 25 or Fiber Mat 45

       Well, that depends. The 25 & 45 in the names are the thickness of each in millimeters. As explained in our Reference Information & Guide page in the sound absorbers section, the thicker absorber of equal material will be better in performance, especially the lower in frequency you go. There isn’t a good chance I can tell you what to use in your situation as I have not worked on a majority of cars out there. Generalizing, I’d say about 60% of cars out there can fit Fiber Mat 45 in the door panels, most can fit Fiber Mat 45 in between the roof and headliner, most can fit Fiber Mat 45 in the wheel liners, and most can only fit Fiber Mat 25 under the carpet. The rest is going to be up to you to investigate the level of clearance you have in your own vehicle. 

When using ResoNix Guardian or ResoNix Lockout, do I need to use a Constrained Layer Damper with it?

       Yes. ResoNix Guardian handles 3 things. Sound absorption, noise blocking, and thermal insulation, while it’s little brother, ResoNix Lockout handles sound absorption and thermal insulation. What it does not handle is resonance control. That is what CLD, such as ResoNix Squares is for. They should be used in conjunction as a sound treatment system.
