Reinforced vinyl fiberglass
Review the four tear-resistant reinforced vinyl fiberglass insulation facings (below).
Why Reinforced Vinyl Fiberglass Is the Top Choice for Metal Buildings and Pole Barns
Industry professionals often recommend reinforced vinyl fiberglass insulation as the most durable and energy-efficient solution for metal buildings and pole barns. These high-performance fiberglass batts come with a tough, tear-resistant vinyl facing reinforced with polyester scrim.
This reinforced layer not only boosts durability but also acts as a built-in vapor barrier, helping to prevent moisture, condensation, corrosion, and mold—all of which can compromise your building’s performance over time.
While options like spray foam and rigid foam board are available, the most popular and practical choices remain reinforced vinyl fiberglass and reflective insulation for metal structures and pole barns.

“We can present YOU savings because we have the buying leverage and willingness to do so! – Owner John Barber
Imagine you’re in the market for fiberglass insulation. The traditional way to proceed is to approach different outlets and ask for a quote. Then, you patiently wait for all your quote requests to return, hoping at least one price will excite you.
But consider this: What if randomly requesting quotes from traditional outlets is the problem? What if the quotes that come back are higher than expected? What if the materials quoted are slightly different on each returned quote, making it difficult to compare them accurately? In such a scenario, what should one do?”
Now, could you consider choosing a different starting process? Instead of depending on traditional outlets to give you their quoted price, you calculate the wholesale delivered price online, verify a savings, and then purchase for a low flat brokerage fee.
With Factory Steel Overstock, you buy from an independent broker that has maintained an A+ BBB grade and 5-star rating since its inception. Think of it like this: Factory Steel Overstock helps you buy something for less than you can buy it on your own. You pay the certified supplier directly and pay FSO for the savings provided. It is a risk-free savings program. You pay nothing until you see the savings!
Why Don’t Traditional Companies Share Their Actual Cost?
Have you ever wondered why traditional fiberglass insulation outlets hesitate to reveal their wholesale price or let you buy online? Essentially, these sellers worry that if they disclose their wholesale price, the average buyer will request or demand a price reduction, threatening their profit margins.
Also, selling online reduces margins. It’s that simple! These sellers know the more ignorant the buyer is of the actual cost, the higher the probability of earning more from them. Moreover, offering retail prices ensures the seller a cushion for negotiations.
You’d like to know the wholesale fiberglass insulation price because…
- You want to be empowered!
- You don’t want to haggle!
- You want the assurance you are not overpaying!
Traditional companies don’t want you empowered. If they did, they would sell with full transparency!
Did You Know?
Most of the vapor barrier fiberglass insulation and metal buildings sold across the U.S. originate from just a few major manufacturers. These large corporations distribute their insulation products—including moisture barrier insulation—through layers of retail outlets, including subsidiaries, regional dealers, contractors, and general resellers.
Here’s the truth:
Even if you gather 20 quotes, chances are you’re reviewing the same exact material—just sold by different outlets, each tacking on their own markup. These traditional sellers have no real incentive to offer the lowest prices on vapor barrier insulation. Their profit is often tied to how high they can price the material.
Now, we’re not saying there’s anything wrong with these companies. But the reality is that their lack of price transparency is what makes customers feel like they need to keep shopping around.
That’s where Factory Steel Overstock (FSO) flips the script.
Instead of profiting more when you pay more, we operate on a cost-plus pricing model that ensures both seller and buyer benefit from genuinely low fiberglass insulation prices—especially on vinyl-faced and vapor barrier fiberglass insulation rolls.
Because FSO is an independent broker, we’re not limited to promoting a single brand or supplier. That independence allows us to leverage our network to access the lowest wholesale rates and pass those savings directly to you. And the best part? There’s no upfront cost. Before you even pay our listed brokerage fee, you’re able to see and confirm your net savings. It’s like having access to discounted insulation and steel buildings for sale every day.
How Our Program Works:
- You receive direct pricing on wholesale vapor barrier fiberglass insulation
- Pay a one-time brokerage fee—only after confirming savings
- Eliminate middleman markups from commission-based reps
- Enjoy full service—from order submission to delivery and beyond
- Experience our A+ BBB rating and 5-star customer reviews
Founded by a 39-year industry veteran, Factory Steel Overstock was built on a spiritually grounded mission: to create honest, mutually beneficial transactions between buyer and seller. That commitment to fairness is why nearly all new orders come from repeat clients, referrals, and organic search traffic—not ads or pushy sales tactics.
About 15 years ago, a friend suggested I use a car broker for my vehicle purchase. I went ahead despite my initial skepticism due to a $500 upfront fee. To my surprise, the broker presented the car with all the features I requested. The best part is that it saved me thousands of dollars! This inspired me to present an even better program: Reveal an actual wholesale cost that confirmed savings before expecting ANY fee payment!
The misconception that “you get what you pay for,” touted by retail sellers, leads the majority to believe that higher prices equate to better quality. This misconception drives people to stick to the outdated practice of seeking quotes from traditional retail sources, thinking the best deals are only there.
Many need to realize that traditional outlets inherently charge retail, as there’s no incentive for them to do otherwise. The more you pay, the more they make! The public, conditioned to accept retail practices, continues to pay retail fiberglass insulation prices without considering the obvious. They will always pay retail unless they buy from a source that is not financially motivated by increased profits.
Since Factory Steel Overstock posted the brokerage fees upfront, offering the lowest wholesale prices is in their best interest.
You have two choices: keep requesting quotes from traditional retail outlets or utilize Factory Steel Overstock’s buying leverage, expertise, and specialized knowledge.
“Easy process. Do your homework, know what you want when you call and you will save $$. I saved hundreds over other prices I got.” – Brad Lezzi 1/10/2024 (Fiberglass Insulation Order)
It is Different HERE
In an industry full of hidden fees, vague quotes, and confusing markups, we choose a different path—one guided by values. Factory Steel Overstock transparently list prices! While many companies conceal their pricing until they’ve got you on the phone, we believe in being upfront from the start. Why? Because we’re not just selling fiberglass vinyl-faced insulation, reflective insulation, or metal buildings, we’re building trust.
