WMP-VR-R
Normal Strength
The WMP-VR-R (plus) is priced on SALE!
It features a thinner vinyl layer, making it easier to roll, cut, and install for DIY projects.
It has very sturdy white polypropylene film reinforced with fiberglass/polyester scrim.
Featuring a tri-directional scrim.
Its tensile strength is 35 lbs per inch.
The Mullen Burst PSI is 100, making it far superior to the WMP-VR facing.
The metalized polyester back allows it to reflect radiant heat away from the structure.
The fire rating is Class A-1.Perm Rating is 0.09.
When you choose WMP-VR-R (plus) vinyl-faced insulation, you’re not just saving money; it meets Class 1 vapor barrier standards and has the structural integrity you can feel good about.
WMP-10
Enhanced Strength
Choose WMP-10 kraft facing insulation for standard steel buildings where insulation will be visible but not exposed to abuse. The fiberglass-reinforced vapor retarder facing features polypropylene/scrim/kraft (PSK) laminated material, offering basic durability and moisture control.
WMP-10 has a tensile strength of 40 lbs. per inch
Featuring a tri-directional scrim.
The fire rating is Class A-1.
Perm Rating 0.2
Select WMP-10 (0.2 perm) for projects needing a tighter vapor barrier than WMP-VR-R (plus).
WMP-10 is NOT ideal when the insulation is exposed to Sunlight / UV, which may degrade the kraft side over time.
Also, when the facing is going to be exposed in high-traffic / rough-use areas.
WMP-30
Industrial Strength
Select WMP-30 kraft-faced insulation if you want the same vapor barrier as WMP-10, but with slightly greater resistance to tears and punctures.
The WMP-30 has a tensile strength of 40 lbs per inch or more.
The Mullen Burst PSI is 70 lbs.
The fire rating is Class A-1.
Featuring a tri-directional scrim.
This insulation is often selected when the insulation may be exposed to wear and tear (retail stores, recreational centers, busy shops).
However, WMP-30 has a thicker facing; therefore, it is heavier and thicker. Which means rolls are stiffer and less flexible. This means it will be more challenging to manage in tight spaces, around curves, or for a single person.
WMP-50
Premium Strength
WMP-50 vinyl-faced insulation is the ideal choice for high-abuse areas and exposed applications that require extra durability.
WMP-50 has a tensile strength of 65 lbs per inch. The Mullen Burst PSI is 120 lbs.
The fire rating is Class A-1.
Perm Rating 0.2
The metalized polyester back allows it to reflect radiant heat away from the structure. It features a tri-directional scrim.
Select WMP-50 when you need a facing to withstand the abusive conditions often experienced in warehouses, factories, distribution centers, gymnasiums, recreational centers, sports facilities, and buildings with heavy equipment, such as tractors and forklifts.
Since it is thicker and stiffer, it is more difficult to install in tighter spaces.

A Higher Conscious Selling and Buying Program
Factory Steel Overstock (FSO) operates a non-dual selling program. In other words, it sees the customer and itself as ONE entity, not two or separate. Thus, it empowers the customer to determine the added profit rather than relying on traditional commission-based salespeople who often over-inflate margins for their own benefit. Most customers find selecting the profit amount akin to deciding the tip amount for a server or a pizza delivery person—basing it on the perceived value of the service. Many find this pricing control a welcome relief and enjoy compensating Factory Steel Overstock fairly.
With that said, if someone is combative or attempts to be deceptive, FSO reserves the right to refuse the order or ban the person from purchasing. FSO will not compromise the integrity of the program for a sale, regardless of the order size.
In appreciation of FSO’s transparency, since 2013, the public has rewarded it with 100% of its new business coming from referrals, repeat customers, and organic searches.

Do You Learn Your Building’s Square Footage?
All insulation types have their market niche, as well as pros and cons. Factory Steel Overstock could offer every insulaton type on this site; however, we have elected to offer what we consider the most cost-effective for metal buildings and pole barns.
Fiberglass Vinyl faced Insulation vs Spray Foam
COST:
One of the most expensive insulation options on the market is Spray foam. Unlike fiberglass, which is a popular DIY material due to its ease of installation, spray foam is far more labor-intensive and usually requires professional application. With a metal building, a layman simply rolls the vinyl-faced insulation over the purlins and girts, then pins it down while installing the sheeting material. Although Spray Foam may offer a higher per square foot thermal efficiency than fiberglass viny faced, one has to consider the additional initial investment required.
HEALTH FACTORS:
One must also consider that the chemicals used in spray foam can release toxic gases if not installed properly. That is not an issue with fiberglass vinyl-faced insulation. It is imperative that one verifies that the space being insulated is well-ventilated and that all safety measures are implemented during installation.
EXPANSION:
Fiberglass Vinyl-faced insulation is not going to expand; however, the nature of spray foam is to expand as it cures. This can sometimes lead to unwanted pressure on drywall and framing if not closely watched during installation.
Fiberglass Vinyl-faced Insulation vs Reflective
Effectiveness in Cold Climates
Reflective insulation is designed to reflect radiant heat away from your metal building or pole barn; therefore, it is an ideal insulation type in hot climates. Its primary purpose is to keep your structure cool; however, most locations require insulation to address climate conditions for all seasons. In other words, an insulation that also deals with winter temperatures. Reflective insulation has a limited ability to resist heat flow, which makes it less effective in cold climates. For this reason, fiberglass vinyl-faced insulation is a more practical choice.
Airspace Installation Requirements
Simply put, reflective insulation requires a gap to be effective, and there are situations where this may be a challenge during installation. This is not a requirement with Fiberglass Vinyl-faced insulation.
Although all insulation types have their market niche, pros and cons, fiberglass vinyl-faced insulation is the most preferred type for DIY projects. Questions, call 1-888-512-1116.
How Many Companies Sell Their Metal Buildings
We generally don’t comment on the practices of other metal building suppliers. However, a recent experience shared by one of our customers moved us enough that we felt compelled to pass it along.
The customer had already purchased a metal building from a well-known company 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 independently, 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 building through us and come out ahead, with a net savings overall.
The lesson learned: NEVER purchase a metal building without having all desired accessories included in the initial quote!

Reflective “Barrier” Insulation
“I have been a part of two orders and now working on my third…” Dave Muniz
Although fiberglass insulation is overall a better thermally efficient insulation product for locations with cold and hot climate conditions, reflective insulation can be an effective radiant barrier in exclusively hot climates. Factory Steel Overstock offers a radiant, vapor, and air barrier reflective insulation that is far superior to bubble insulation.
