Standard Poly Backed Carpet Vs. Special Order Mass Backed Carpet

The only difference between the mass backed and the standard poly backed carpet is the addition of sound deadening backing material called "mass backing". Mass backing material, which is approximately 40 mil thick, is heat bonded to the back of the standard poly backed carpet. It's purpose is for additional sound deadening and heat shield. It does, of course, make the carpet's overall weight heavier due to the addition of the backing material. Each style carpet, whether you order the standard poly backed or special order mass backing, will wear as long as your factory original carpet did. The carpet itself on both products is identical in every way. Only the addition of the mass backing material differs between the two. The pile is approximately 1/4" deep. Included in each set is heavy 40 ounce jute padding for the floor pan areas. After installation, you cannot tell by looking whether you have the standard poly backed carpet or the special order mass backing on your carpet. If you are looking for additional sound deadener for your vehicle, then the special order mass backing is the product that you have been looking for. It saves time--you don't have to lay down sound deadener...then install your carpet, you can do it in one step. Mass backing is a product that we highly recommend, however, the standard poly backed carpet wears equally as long and is the identical carpet without the extra sound deadener! Some late model vehicles (1990-present model year) have mass backing. You should look on the back of your original carpet to determine if you do have the mass backing on your vehicle now. If you do, it is recommended that you replace the carpet with the mass backed carpet. Mass backing is a special order item available at an additional cost. Special orders do not take any longer to manufacture and ship than our standard poly backed carpet. Most carpets ship in 24-48 hours after your order is received. The majority of our customer's have their products in their hands in 7 days or less, of course, that is dependent upon where you are located in the US.
