New Sound Deadening

We will be bringing these in shortly.

Ground Zero decided to expand the line up of damping material with three additional items: GZDF 1600-SA, GZDM 1850-ML and GZDM 3700-AB.

The GZDF 1600-SA is self-adhesive and based on viscous polyurethane foam for vibration and maximum sound absorption and heat proofing. The gift box includes 8pcs of 15mm / 0.59” thick sheets. That's a total 1,60m² / 17.22 ft².


The GZDM 1850-ML damping mat is a 4,5 mm / 0.18” thick, self-adhesive, flexible and elastic vibro-damping material. It´s a multilayer combination of aluminium butyl and a flexible damping foam for excellent sound absorbing. The gift box includes 20 panels which makes in total 1,84m² / 19.80 ft²


The GZDM 3700-AB is a classical aluminium-butyl damping mat. It comes in a big gift box of 40pcs 1.7mm / 0.07” thick panels which is in total 3,68m² / 39.61ft².

Wow...that's some cool stuff. Are the first two water-resistant?

I would assume so, but I will shoot a email off to them to verify.

The acoustic foam panels look very solid, and the prices are reasonable as well.

The prices should be really good. Taking the AB product for example. Its 1.7mm thick and 40sq ft cost $140, if we compare that to Second Skin Damplifier which is 1mm thick, we are $5 more for 40sq ft. If we compare it to the Damplifier Pro, that is 2mm thick and costs $203 for 36.5sq ft.

I need to compare its retail prices towards some of the other brands, but I think it will be priced just fine for whatever it is being compared to.

I would also be interested to know if the SA is water resistant. That would be amazing for my door panels.

Are you guys going to do an MLV?

Lastly, what temperature ranges are the products tested to?

Thanks.

The multi layer is, the SA is not. The SA is meant for in between the panels on the interior of the car.

I have not heard anything about a MLV product. I do not know any specifics on the temperature ranges, but I do not think you will have a problem with any of the adhesives on our products.

Thanks, Scott.

I understand why you may not want to publish temperature numbers, but please do if you can.

And please let us know when you find out about water retention and the SA product.

Its not a matter of not wanting to, I just do not have that data. I will see if I can obtain it. But this is not their first go at sound deadening. We have other products that are manufactured in Germany, they carry the made in Germany price tag though. The products are sold all across the globe. They use GZ sound deadening in places much hotter than most of the US with no problems.

The SA product is not made to be in wet/moist areas like inside of the door cavity. It is made to be on the interior of the car between panels. The ML will be fine in the door cavity.

Gotcha. I don't mean to be difficult, I am interested in the SA product and want to understand how I might be able to use it in my build.

Thanks.

I installed some of the GZDM-3700-AB today, and must say that I was very impressed with it. Very sticky, very flexible and is very effective.

Glad to hear :) We have a good bit of all 3 products coming in at the end of this month.

Scott, did the SA product come in?

Thanks.

Looks like my shipment should be hitting the warehouse on Tuesday, we will have plenty of all 3 different ones.

I have plenty on order. Looking forward to using all 3. The Charger will get it's fair share.

SA is in stock now, along with the ML and AB, we have had it for a few weeks now. Dealers and users have really been liking it all.

Scott, is one of the goals of the SA material to negate the need for MLV? Did Ground Zero do any comparisons between the SA and MLV for sound blocking capability? Thanks for any parameters and results you can provide.

I would not say it negates mlv. It has some sound absorbtion properties, but it is really good for putting between the door card and inner metal door or any other panel, to help stop vibrations. It is not a water resistant product due to not being a closed cell product. So do not use it inside the door cavity. The ML can work in there.
