Reinforced Facing Accessory Types
Reinforced facings are available for a wide variety of uses and budgets. From light duty to heavy duty applications, there is a reinforced facing product to meet your needs.
WMP-VR has polypropylene on the front side and natural kraft paper on the back side. This is the lowest priced reinforced facing available, and it is the industry standard used in typical metal buildings that only require standard duty insulation. It is 0.09 perm and has a bursting strength of 60 psi.
WMP-VR-RPLUS is polypropylene faced and metallized polyester backed. It is the most commonly used type of reinforced facing. The metallized polyester backing provides additional strength and water resistance. It has a permeance of 0.02 perm and a bursting strength of 100 psi. It is used in metal buildings that do not require heavy facing.
WMP-10 has polypropylene on the front side and white kraft paper on the back side. It is slightly heavier than WMP-VR so it can stand up to light to moderate traffic. The white kraft paper provides a better water vapor barrier (0.02 perm) and a little more resistance to impact (65 psi bursting strength).
Similar to WMP-10, WMP-30 has a polypropylene front and white kraft paper back but adds additional thickness and strength. It is better suited for heavier duty jobs and in areas with moderate to heavy traffic. While it has the same vapor barrier strength as WMP-10 (0.02 perm), WMP-30 is superior in terms of bursting strength (70 psi).
WMP-50 has polypropylene on the front side and metallized polyester on the back side. It is twice as heavy and strong as WMP-VR-R, making it a good choice for metal buildings when the walls are exposed to heavy traffic and abuse. It is a premium heavy duty product with a permeance of 0.02 perm and bursting strength of 120 psi.
WMP-UV HD has a polypropylene front and metallized polyester back but adds additional UV resistance. It is also twice as heavy and strong as WMP-VR-R. It matches WMP-50 in terms of permeance and bursting strength. It is particularly well-suited to building applications with large amounts of sunlight.
R-3035 HD is a different type of reinforced facing. It is made with heavy duty foil, scrim and kraft paper. It has a permeance of 0.02 perm and a bursting strength of 60 psi. This makes it a good vapor barrier for moisture control, but a better choice in areas that are not susceptible to damage like rips, tears and holes.
