Design Ideologies
Car Builders’ Stage 1 sound deadening material is a thin, flexible, easy to cut and mold sheet that combats problematic resonance and vibration. This is achieved by using a specially blended chemistry which is conducive to vibro-acoustic energy conversion. Put succinctly; that annoying noise becomes silent energy. Stage 1 uses a specialised damping process that involves restraining vibrations and noise by dissipating or using up the energy causing those vibrations. Via this process Stage 1 converts the movement of the vibrations into silent, low-grade thermal energy which is easily dissipated.
It’s In The Build
Car Builders’ Stage 1 sound deadening consists of a butyl rubber noise absorption layer combined with an aluminium top layer. Each box has 12 sheets, each sheet is 300 mm x 500 mm and 2.1 mm thick. Stage 1 is a butyl material meaning it does not require heating, does not smell and will not go brittle over time; all detractors of the old style tar or bitumen sound deadening materials. This butyl is a pressure sensitive compound, which is inherently sticky thus eliminating the risk of an adhesive layer failing.

A Little Background
Just to give a quick overview; sound deadening absorbs vibrations and adds mass to panels. This process will make your car or van quieter as it will reduce the resonance of the panels, removing that tinny sound thin sheet metal panels have. This will reduce echo and make the inside the vehicle a much more comfortable place.
Sadly sound deadening is generally a misunderstood material. Normally the first stage of treating noise is referred to as sound deadening. This stage only really treats vibration in panels. It was often a bitumen-based product but more commonly consists of a butyl rubber with an aluminium top layer. Cheaper sound dampening sheets consist of a lower grade butyl, which is not as durable or resistant as those used by high-end brands. Butyl sheets by themselves however, will not result in dampening droning or external noise that you may be more interested in treating. This will be treated more successfully with mass loaded vinyls. If you are aware of the type of sounds that are annoying, you will be able to treat them more successfully with targeted products. If you’re unsure shoot us an email.
Sound Deadening As A Term
This term is often confusing. In physics it means restraining of vibratory motion. This includes mechanical oscillations, noise and alternating electric currents by dissipation of energy. In a general sense to dampen means to make less strong or intense. There are five common elements to reducing sound; absorption, damping, decoupling, distance and adding mass. Automotive structures limit the thickness of materials that can be used, but combinations of dampers, barriers, and absorbers are used to reduce sound. Surface damping materials such as butyl-based sound deadening sheets are very effective at reducing structure-borne noise.
