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.

Features / Benefits

Dual Car Soundproofing Function — RoadBlockR™ Damping Material reduces road noise and improves car audio system performance.

Ease of Installation — RoadBlockR™ Damping Material is easy to install with a “peel and place” application. Simply trim the pieces to fit, peel and place and hand roll to ensure good adhesion. No messy spray-on paints or adhesives are needed to install this product.

Value — RoadBlockR™ Damping Material is priced to be cost effective, when compared to similar products on the market. Car soundproofing does not have to be expensive to work!

Low Profile — RoadBlockR™ is only 0.078 inches thick, so it will fit in the tightest spaces. Sheets of RoadBlockR™ are easy to trim so custom shapes ca be created.

Packaging — RoadBlockR™ is packaged in 'stay-flat' boxes for product protection. No more creases or annoying folds to smooth out. Also, the Pressure Sensitive Adhesive protective backing stays in contact with the material so it will not dry and potentially compromise the application.

In-stock — We stock RoadBlockR™ Damping Material in large quantities. Most products are shipped the same day they are ordered and arrive at your project in one to three business days, depending on your location.

Not Just for car soundproofing — RoadBlockR™ Damping Material was originally created for applications that required extreme damping. This product will quiet any sheet metal application. Also used in the HVAC, heavy equipment and audio industries.

Why RoadBlockR™ ?

RoadBlockR™ was engineered for car soundproofing and sound dampening from the beginning, unlike some other products that are really repurposed asphalt roofing material. Originally designed for the automotive industry, RoadBlockR™ has incredible sound dampening and enhancement properties. This product will decrease road noise within the cab and improve car audio performance. RoadBlockR™ is a technologically advanced formulation that offers superior damping performance at a reduced weight over traditional mastic constrained layer and asphalt extensional dampers. It is a visco-elastic, extruded rubber based damping system with a 3 mil aluminum foil on one side designed to reduce structure-borne sound. Excellent damping performance is maintained from 10°F to 140°F. It is available in sheet or die cut form and comes standard with an aggressive PSA backing. Applications include auto floor pans and doors, metal trays, carts, major appliances and construction equipment.

Why Car Sound Dampening is Important

Dampening is one of the most effective things you can do to your car to improve audio performance and sound quality. By reducing or dampening sound vibration in the metal panels of your car, you can eliminate road noise transmission. By reducing sound transmission and loss out of your car you can keep road noise out and your tunes in!

    I have a mint '69 mustang, it's my baby. I loved driving it but it was so noisy it was almost unbearable. I'd heard so much about other products but I was able to find the RoadBlockR and it was much cheaper so I decided to go with that. I don't know how good some of the other advertised stuff is, but Roadblockr works great. I'm gonna do my wife's SUV here soon.
