ResoNix Lite – CLD Rectangles – Lightweight Sound Deadening Material

9 Pieces – 36 Square Feet


Please note, our ResoNix CLD Rectangles Sound Deadening Material does NOT have the same performance level as our ResoNix CLD Squares Sound Deadening Material. The Rectangles are a thinner product that competes closer in performance and price with other well known brands products on the sound deadener market. See specs below.

ResoNix CLD Rectangles is a lightweight sound deadening material product (constrained layer damper) comprised of butyl rubber and aluminum. It adheres to panels of the car to lower structure-borne vibration and resonance for a lower noise floor and a better foundation to build a sound system off of. ResoNix CLD Rectangles sound deadener is our more price-friendly CLD product that competes in a similar price and performance range as other products on the market. Its focus is on applications that need lightweight sound deadening material, and applications that are budget-restricted.


Our ResoNix CLD Rectangles sound deadening can be used to treat resonance and vibration in many different applications. It is most commonly used on the following…

Door Skins – Door Panels – Trunk Lids – Hatches – Rear Decks – Rear Deck Cover Panels – Roof Skins – Wheel Wells – Wheel Liners – and More!

We get emails regarding this often. The problem is, every application and situation is different. Every panel is different, every car is different, and everyone’s end goals are different. With our Reference Information & Guide section, and our ResoNix Sound Deadener Buyers Guide, we try to give you as much information as possible in order to help you make the most informed decision possible. But to make it very quick and simple, in our shop, we almost never do less than 60% coverage on panels that require treatment. This includes door skins and panels, rear decks, roofs, quarter panels, trunks, interior plastic trim, and more. In cases where we are just trying to achieve the best end result possible, we aim for nearly 100% coverage. We figure if we are doing it, we may as well do it once and do it right. 


An excerpt from our sound deadening Reference Information & Guide page. 

A Constrained Layer Damper works by using a viscoelastic layer (the butyl) and a constraining layer (the aluminum) to convert mechanical energy (the vibration of a panel) into heat via the viscoelastic properties of butyl while the constraining layer helps the panel keep its shape and resist deformation.  The primary way that CLD achieves this is through shear forces in the butyl layer caused by being constrained between the panel and the constraining layer while the panel is vibrating (bending). When the panel flexes and deforms, the viscoelastic layer naturally resists and wants to “snap” back into place. See Figure 1. (Click to expand)

Figure 1.

ResoNix CLD Squares should be used where you want to cut down on any structure-borne vibration and resonance. Long, flat, and thin panels, like outer door skins, door panels, quarter panels, and roof skins are the biggest offenders. Reducing structure-borne vibration helps lower the overall noise floor of the vehicle while also lowering the resonance caused by sound systems to an acceptable level.  This can result in a faster decay of bass and midbass frequencies.  Slow decay in these frequencies can cause “muddy” sounding bass response or can make it seem like repeated fast bass notes are blending together.  See figure 2. (Click to expand)

Figure 2.

ResoNix CLD Squares are the best choice for all applications where you want to attack structure-borne vibration to reduce undesirable resonance and vibrations. We chose a butyl compound specifically designed for vibration damping and paired it to an aluminum layer thickness that is as stiff as possible, without risking weakening the adhesive bond on contoured panels.

Our detailed how-to guides on how to get the most out of our products can be found in our Reference Information & Guide section. In the meantime, please properly clean the surface of all dirt, grease, and oils before application, and use a roller to properly adhere the CLD Squares to your panel. No heat is necessary.
