The most popular fiberglass vinyl facing choice is WMP-VR-R (plus), followed by WMP-50.
WMP-VR-R (Plus)
Superior Strength
Our WMP-VR-R has higher tensile strength than WMP-VR, WMP-10, and WMP-30, rated at 130-150 lbs. per inch. Its puncture resistance is 45-60 lbs per inch. It has a perm rating of approximately 0.02. This means it offers exceptional vapor barrier protection. The fire rating is Class A-1, and the metalized polyester back allows it to reflect radiant heat away from the structure. It is FSO’s #1 seller!
WMP-10
Adequate Strength
The WMP-10 features reinforced vinyl-faced fiberglass insulation, offering a puncture resistance of 25-35 lbs. per inch. It provides adequate moisture protection (0.09 perms); however, since WMP-VR-R (plus) is on sale and has a superior perm rating of 0.02 (for moisture protection) and tensile strength, it is currently the better purchase. There is additional information on WMP-10 on the order page.
WMP-30
Industrial Strength
The WMP-30 reinforced vinyl fiberglass insulation is the ideal insulation for high-humidity areas, with a perm rating of 0.2. It has superior moisture resistance, improved thermal performance, and greater durability, thanks to its superior puncture and tear resistance, as well as its tri-directional scrim, compared to the WMP-10.
WMP-50
Premium Strength
The WMP-50 reinforced vinyl fiberglass insulation provides even greater moisture resistance, superior thermal performance, and enhanced durability compared to the WMP-VR-R, WMP-10, and WMP-30. It is an ideal choice for high-abuse areas and exposed applications needing extra durability. It is FSO’s #2 insulation seller.
Fiberglass Insulation Blanket Roll Dimensions
Standard Length: 30′ – 100′.
Standard Width: 3′, 4′, 5′, and 6′
Cuts shorter than 30′ are an additional cost.


Tape and Banding for Vinyl faced Fiberglass Insulation
To maintain the insulation’s thermal efficiency, order patch and/or double-side tape and/or banding and screw (white or black).
Two-Sided
$35
Double-sided tape is normally purchased when the sheeting hasn’t been installed. It temporarily holds the insulation in place until the sheeting is installed.
3″ x 150′. Recommended one roll per 2,000 square feet.
Patch Tape
$35
Although the facings have superior puncture and tear resistance, patch tape is used to repair tears, seal gaps, joints, and seams, ensuring a continuous thermal barrier.
1/2″ x 60′. Recommended one roll per 15,000
Banding
$195
Banding is normally purchased when installing faced insulation in a retrofit application. It is used to prevent the insulation from sagging and shifting.
One roll of 500′ banding per 1,000 square foot of coverage.

An Actual Metal Building Purchase Reality
We don’t typically comment on the practices of other steel building suppliers. However, a recent experience shared by one of our insulation customers is essential enough that we feel compelled to pass it along.
The customer had already purchased a steel building from a well-known seller and came to us afterward for insulation. Naturally, we asked why he hadn’t purchased insulation—and other necessary components—from the original supplier. His response was eye-opening.
He said the seller’s initial offer included only the bare-bones building—no framed openings, walk doors, windows, or essential accessories such as closures. He was told these items would be more affordable if he waited for a project coordinator to follow up after the purchase.
When the coordinator did reach out, he presented a list of add-ons—many of which are critical for any steel structure—at prices that were, frankly, outrageous. In fact, the cost of these “extras” exceeded the original price of the building.
The customer found himself in a difficult position. Having already paid a deposit and lacking the experience to source these critical components on his own, he felt pressured to move forward and pay the seller’s inflated prices.
Fortunately, after reviewing the proposal with us, he discovered that even after forfeiting his deposit, he could still purchase the necessary materials through us and come out ahead, with a net savings overall.

What if a company were willing to share its actual wholesale cost with you? What if this firm also allowed you to suggest the added profit amount? What if this company had the integrity to let you know whether you were offering more than you needed to? What if their acceptance of your offer was based on whether your actions reduce or increase their operational costs? What if the company informed you of the steps required to earn the lowest profit amounts? Would this company be providing the perfect selling program?

On the contrary, its interest is in creating an authentic win-win scenario for both the seller and the buyer. The owner is a 40-year industry veteran and practicing Spiritual Practitioner who has witnessed firsthand the pervasive use of unfair selling tactics, including hidden fees, sales gimmicks, and vague quotes, particularly in the sale of metal buildings by commission salespeople. He felt compelled to level the playing field by providing the necessary tools to neutralize the advantages.
Anyone—not just contractors—can access authentic wholesale pricing on this website by using the Wholesale Calculators. With this crucial vinyl-facing insulation and metal building pricing tool, the public is protected from the gimmicks posed by nefarious commission salespeople and the unbalanced profit determinations by retail corporations.
