Step up to the next level in safety, strength, and performance. VB Armor is stronger than 30-pound felt, but it’s lighter and easier to handle, making your job easier. VB Armor includes all the features of VB Shield, from the cutting-edge SlipGuard walking surface to five times more coverage per roll than Type 30 felt.

Like VB Shield, it meets building codes for residential and commercial projects, it is completely inorganic and asphalt-free (meaning no rotting or molding), and it is treated to resist excessive degradation from normal UV exposure for up to six months. So when you need the next level in roofing underlayment, VB Armor delivers premium quality you can count on.
