Frequently Asked Questions
What is the Difference Between Black & Silver Backing?
Performance wise? None! Both the black and silver backing HushMat Ultra sound deadener perform the same. We typically keep black in stock.
Who Else Uses HushMat?
HushMat is the only SAE approved sound deadening material and has been used on virutally every new car built in the United States, Canada or Mexico in the last 20 years.
The SAE (Society of Automotive Enginners) is the standard approval used within the automotive industry to qualify products and suppliers.
Where Can I Use HushMat Ultra?
HushMat Ultra is designed to be used on any metal, vehicle surface. Because of it's adhesion guarantee, the same product can be used on the floor, doors, firewall,
cargo area, or even the roof!
How Much Does HushMat Ultra Weigh?
HushMat Ultra weighs approxmiately .50 lb per sq. ft. It is not quite .50 lbs/sq. ft, but just under it as this is considered the optimal sound deadening weight for vehicles as determined
by the SAE.
Should I add Silencer Megabond?
Silencer Megabond is a great addition to the Ultra material and is designed to block frequencies from 1000Hz to 4000Hz while also blocking up to 60% of thermal transfer when combined with
HushMat Ultra. We recommend using both together for the ultimate sound and thermal damping, but Silencer Megabond is not required!
