RoadBlockR is a premium car soundproofing product. Serious car soundproofing requires serious soundproofing material. RoadBlockR™ was engineered to provide this benefit. Originally designed as an industrial sound damping material for applications that need extreme performance, it is well suited to the demanding car enthusiast. Whether you are trying to improve the quality of your car stereo or give your vehicle that “luxury car” feel, RoadBlockR is the ideal material. By reducing the sound that is transmitted by the surfaces of your car, you can reduce noise clutter. You hear more of the sound you want to hear and less of the road. RoadBlockR is specifically designed to substantially reduce the sound transmission of metal surfaces giving you a quiet space to enjoy your tunes. No more bass masked by the drone of the road or vocals crushed by an unruly exhaust.

Introducing RoadBlockR Auto Noise Control

The last thing you want to hear while you’re soaring down the highway cruising behind the wheel is a rattle, squeal or the thump of the tires against uneven asphalt. You need expert car sound deadening to keep those sounds from infiltrating the peace of the interior, but that’s usually not available on all but the most expensive autos. Cheaper alternatives are available, but they’re often hard to apply and run the risk of damaging your vehicle. Unless you’re an expert, DIY sound dampening material for cars can simply be too intimidating to risk — or, at least, that used to be true. Mooo-ve on over for the latest technology available from Soundproof Cow. Our RoadBlockR peel-and-stick car soundproofing seals out road noise so you can enjoy every minute you spend on the road. One of the main reasons our products stand out is the thorough the design and testing processes they go through. RoadBlockR is geared toward creating cabin comfort. Our focus is on the driver’s experience, and we only trust materials designed with drivers in mind to follow through on that promise.

Expect the Best From Soundproof Cow

Loyal customers know we only sell the best products for controlling noise and improving acoustics. If RoadBlockR wasn’t capable of controlling vehicle noise on and off the road, we simply wouldn’t promote it. Highway noise rates around 75 decibels, so your soundproofing solution has to be able to handle a hefty job. RoadBlockR is in our listings because it manages to be extremely effective without breaking the bank. In fact, RoadBlockR is used for heavy-duty applications when only the best sound dampening will do. Its low-profile design allows for maximum flexibility, and the design provides noise control even in high-temperature situations. As much as shoppers trust our products, they’ve also taken a shine to our policies. It helps that we have a reputation for standing behind our products. Every item we sell is covered by a 100% customer satisfaction guarantee. We start by selecting the highest quality materials, but rest assured, if there are any problems with your order, we’ll work with you until they’re solved.

The times I talked with you on the telephone and corresponded through email you have been very helpful and efficient. I would highly recommend to anyone!

– S. Cimino, PA

I have emailed a lot of different manufactures and I have to say your customer service is head and shoulders above all of them. I emailed your company at about 9pm my time and when I woke up the next morning you had already answered my question and then the follow up was a few hours later. I am impressed. Thanks a lot for the quick turn around!

– E. Gustafson, NV

I just wanted to send a quick thank you for your rapid response and helpfulness. I very much appreciated it. You have been responsive in every way all through the process. It has been a pleasure doing business with you and your company.

– T. Alexander, CA

I just wanted to let you know that in the end, sealing the air spaces on this door worked just fine and took care of the problem.

I really appreciate you taking so much time to share your expertise with me, and in particular recommending I try the simpler solution before investing in more expensive noise barriers. That is a big credit to you and your business.

– Mike
